In today’s episode, I discuss the inner workings of generative AI models like ChatGPT, Anthropic’s Claude, and Google’s Gemini. You’ll gain a behind-the-scenes look at how these models process your prompts, starting with tokenization and progressing through embeddings. You’ll learn why the order and detail in your prompts are crucial for getting the best results from these powerful tools. Stay tuned to improve your AI prompt strategies and learn how these models transform your words into actionable outputs.
Mind Readings: How Generative AI Models Work Inside, Part 1
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
This week, we’re going to get into the blood and guts of generative AI, in particular, large language models like the kinds of power, chat GPT, Anthropic’s Claude, Google Gemini, etc. Over in the Content Marketing Institute Slack, Joel Barker had asked if the short video that I had posted of how a Transformers model works could be something that has a bit of a voiceover to explain what’s happening. So first, we’re going to play through the entire video itself, so you can see what’s happening. This is by B.B. Croft. This is an illustration of what happens in a generative AI model. So, I’m just going to go through, and you can read the explanation along the side. However, the explanation is very, very technical, so let’s just watch and see what happens.
From the moment that you put a prompt in—in this case, a very simple prompt—that prompt then gets tokenized. The tokens are then vectorized and then embedded, and you create the input embeddings. Then it goes to the query key value caches to get dot products, and then this continues on down through the multilayer perceptrons, through the attention mechanism. These are the transformers that are doing their mathematics on it. Then you get to a layer norm, the logits, the logit soft max, and eventually you get the next token in the sequence. Then this happens over and over again.
Now, if you know mathematics, you know lineal algebra and calculus and stuff, it’s pretty clear what’s going on here. If you don’t know those things, it’s not at all clear what’s going on here. So what we want to do is take this apart as a series of what’s going on inside a model, and we’re going to do this probably in multiple parts because the explanation is going to get lengthy. More importantly, what do we learn from it? What does it teach us about how to use AI better? Because it’s cool to understand the architecture. It’s more useful to understand why these things matter so that we can develop better strategies for working with AI.
So let’s get started. We’re going to go back to the top of our model here, and we’re going to start with the prompt. So, when you put a prompt in, the first thing that happens in a generative AI system is the prompt is tokenized. What that means is it is transformed from letters or parts of words or words into numbers because generative AI and all AI is incapable of working with text. These are mathematical tools, statistical tools. As a result, math is the only thing they understand.
So when we type in a prompt into chat GPT, the first thing it does is it has to turn it into math. It has to turn it to numbers, and then those numbers can be processed. Let’s use an analogy. We’ll use the analogy of a newspaper, a very peculiar newspaper. There’s an editor in chief, there’s a writer’s room, and there’s an editor’s room. Ultimately, there’s sort of a typesetting room, and what comes out at the end of the day is the newspaper, right? So that’s going to be our analogical framework for this series.
The prompt is kind of like the editor-in-chief bursting into the writer’s room and says, “Hey, everybody, we got a new assignment, and it’s a big one.” So, we’re going to break up this assignment into little pieces. The editor takes the pieces of the assignment, hands it out to all the writers, and every writer’s got, like, three words to work with on this story. That’s the first step. That’s that tokenization step, where you take the assignment and you break it up into little pieces.
Then what happens is in the next step, right, the embeddings. So the assignment’s been broken up in little pieces. Every writer has to look at the words, or the pieces of words. Maybe they got, like, two words on a sticky. They have to figure out, “How does this relate to other words that I know about?” That’s the token embedding. Then they also have to say, “How does this word relate to other words that we’ve been given in this assignment, in the order in which they appear?”
Because language is not really random, right? You don’t say, “I pledge leads to the flag backwards.” That makes no sense. The sentences make sense. There’s a logical flow of words. Those rules we call grammar. When a model is taking apart our prompt, it’s like all those writers taking apart the assignment but remembering in what order the pieces of the assignment were given, right? If the editor comes in and says, “We’re doing a story on corruption at the docks down in Long Beach, and I need someone to go down and investigate the dockmaster. I need somebody to go to a shipping yard. I need someone to go to container yard,” the sequence of things that the editor-in-chief is giving orders to, we’ve got to remember that, because maybe the sequence matters.
In this fictional case, what if talking to the dockmaster is not a good idea because you need to talk to the shipping receivers first for this fictional story that we’re working on? So that’s the first step: the assignment comes in, gets broken up into pieces, and then assigned to writers. The writers have to figure out what their little piece of the story is, what they know about it, and how it relates to the other pieces.
Those two things are sort of multiplied together inside the model to create what’s called an input embedding, which is almost like a master project plan, if you will, of who’s doing what, in what order, and then it proceeds on. So we’re going to stop there, because this already is a lot.
What do we take from this portion? Just from here, just from this portion, we see that what goes in our prompt has to implicitly have things like knowledge, right? The more relevant knowledge we provide, the more of those writers know what the assignment even is. More detail. A good creative brief has more detail. The order in which the words appear matters. So if we are providing structure and order in our prompts, there’s a good chance that will help improve the performance.
So that’s going to be the end of part one. In part two, we’re going to dig on further as to what happens next in the writer’s room, which is going to be really, really messy. So stay tuned for that.

What’s On My Mind: The Future of Work in an AI World
This week, let’s talk a bit about the future, inspired by several things. First, my friend and colleague Constantine von Hoffman asked what I thought the next 6-12 months look like for AI.
Spoiler: no idea. But we’ll come back to this question in a bit.
Third, this week I started using aider and cline in my software development work, and am properly blown away by both and what they enable.
So, let’s talk about the future.
Caveat lector: the future, by definition, is not set. With the world as unpredictable as it is, by the time I press send on this newsletter, it could very well all be wrong.
Part 1: The Future of Work
We’ll start with the World Economic Forum report. Screenshots and tidbits of it have been floating around on LinkedIn, but let’s dig really into the meat of it. With documents like this, I strongly suggest loading it into a tool like NotebookLM and then asking questions of it. You’ll get credible answers drawn from the document itself.
Here are a few of the specifics:
“Technology is predicted to be the most divergent driver of labour-market change, with broadening digital access expected to both create and displace more jobs than any other macrotrend (19 million and 9 million, respectively). Meanwhile, trends in AI and information processing technology are expected to create 11 million jobs, while simultaneously displacing 9 million others, more than any other technology trend. Robotics and autonomous systems are expected to be the largest net job displacer, with a net decline of 5 million jobs.”
Also from the report:
Today, 47% of tasks are human only
30% are human/machine hybrid
22% are machine only
By 2030, according to their survey:
– 33% of tasks will be human only, a 29.8% decline
– 33% will be human/machine hybrid, a 10% increase
– 34% will be machine only, a 54% increase
And who’s exposed to the greatest risks, in terms of machine substitution by generative AI?
Skills involving reading, writing, and mathematics
Marketing and media
Systems thinking
Multilingualism
Programming
(plus AI itself, as agentic AI consumes more of AI overall)
That wasn’t the only paper that caught my eye over the last couple of weeks. The National University of Singapore published a study on how AI is impacting the freelance market.
The short version of that paper is that when AI isn’t fluent and skilled in a domain, freelancers using AI see big boosts in earnings, up to 65%. Once AI becomes fluent and skillful in a domain – like language translation – freelancer earnings fall by 30%.
Back to the WEF report, one of the whoppers in it was this:
“On average, workers can expect that two-fifths (39%) of their existing skill sets will be transformed or become outdated over the 2025-2030 period. Extrapolating from the predictions shared by Future of Jobs Survey respondents, on current trends over the 2025 to 2030 period job creation and destruction due to structural labour-market transformation will amount to 22% of today’s total jobs.”
Now, let’s talk about this a bit. I’m decidedly pessimistic about the report’s conclusion that we’ll see a 7% net increase in jobs. Why? Because in a free market civilization where net profit is the tangible, measurable goal of most corporations and for-profit entities, the goal is to increase profits while reducing costs.
I do think the estimates for how much work AI will consume ring true; both NUS and the WEF report estimate that AI will consume about 30% of work, which makes sense. But I don’t think labor numbers are right, for one simple reason: tasks are unevenly distributed.
Let’s take the average marketing agency. Companies are inherently pyramid shaped for the most part. There’s very few people at the top, and a whole lot of people at the bottom. At the bottom you have roles like analyst, coordinator, specialist, and other related titles, the junior staff. These folks do the grunt work for the most part.
Preparing and scheduling meetings, assembling reports, taking notes, collecting data, writing first drafts of marketing documents…
You can tell by just that short list of very common tasks that those are all tasks today’s AI tools can do fluently. Meeting note-taking is so automated now that entire companies will deliver AI summaries, to do lists, takeaways, and transcripts of pretty much any meeting audio. Google just rolled this out natively in Google Workspace.
What happens when the bottom level of the pyramid can be done by machine? The next level up – the account managers, account supervisors, account executives become the operators of the machines that are handling the lowest level tasks. And over time, as AI becomes more fluent in more tasks, the number of people you need at each level diminishes.
We used to say, “AI won’t take your job. Someone skilled with AI will.” That’s somewhat true, but not entirely. There are plenty of jobs, especially at the lowest levels of an organization, where all the tasks that comprise that job can be consumed by AI.
But you might say, “Chris, someone still has to operate AI! We can’t get rid of everyone.” No, we can’t. That’s impractical, and as a number of companies found out recently, firing everyone and hoping AI can do everything is not a winning strategy.
Not recently, anyway.
But that’s going to be less and less true over time. Which brings me to part 2.
Part 2: The Future of Tasks
I’ve been creating software with generative AI for well over a year now, ever since GPT-4 conclusively proved it could write at least moderately fluent code. Most of the time, it would write code that was 90% of the way there, but as software developers know, code that is 90% working is code that is 0% working, because code has to be syntactically correct to run. Computer languages are unforgiving; misplace a semi-colon and your entire app might not run.
But that was then. Over the past week, I’ve been playing around with two different AI coders – aider and cline. Both are free and open source, though both require you to provide them access to an AI model of some kind, like Claude, GPT-4o, Deepseek V3, Gemini, Qwen Coder, and other models. I’ve been using Deepseek V3 because it’s comparable to other state of the art models at ridiculously low cost.
When you use a tool like cline or aider, you don’t write the code. You give instructions, prompts, and it writes the code. But it does so within an environment where… it just runs. It’s an example of what the future of AI looks like, tools that run semi-autonomously or even autonomously.
I have a short 1-minute video that’s a time lapse of Cline and Deepseek building an MVP – minimum viable product – inside VSCodium, a coding tool. As you watch it, you see it writing, then editing, then proofreading its code with me only occasionally pushing buttons or giving clarifying instructions.
Tools like Replit do this entirely autonomously now. No human needs to babysit them. You give them the instructions, and they figure it out. It may take a bunch of tries, but it gets there eventually.
How eventually, and how much does it cost? The setup I was using cost me 25 minutes of babysitting time and a whopping 6 cents of compute costs using Deepseek V3.
Now give that some thought. A high value task like building an app – granted, a very simple one – would in the past have taken hours, perhaps days, of a developer’s time at $100 an hour minimum for on-shore developers. Offshore developers cost less, but still cost a good amount of money.
AI accomplished the same task in less time than a lunch break and for less than the tip you’d pay on a soft drink order at a restaurant.
When you watch it code and debug, you’re struck with just how capable these tools are. I provided the idea. I provided the requirements. I provided clarifying answers to questions it had.
That’s it. It provided the skills.
There’s a reason hiring demand for software developers has been near pandemic-level lows for the last year with no sign of recovery, at least according to data from Indeed.com. The job of a software developer isn’t putting fingers on keyboards much any more. The job is now ideating and providing high level guidance – being the expert during pair programming, while AI is the junior programmer.
Can you imagine that same kind of work being done by AI in, say, a corporate strategy document? Going back and forth, making edits and refinements, asking clarifying questions, but doing all the labor itself?
This is why I’m pessimistic about the World Economic Forum’s report in terms of jobs created. I think they’re wildly overstating the number of jobs AI will create. Yes, we will need more expert engineers to solve very difficult problems, but the pathways to becoming one of those expert engineers will be smaller and narrower as AI does more.
It’s also worth reminding that I am not a software developer by training or trade. It’s not a core skill set of mine. I’m a technical person, yes, but not a hardcore developer. So what you see in the demo is a person with an idea and good vocabulary to know what to ask for, but not a coder, doing the job of a junior coder.
In certain circumstances, AI absolutely will take your job. And the list and scope of those circumstances is going to increase over time. Today, for the average user, there is no need to use a human translator to translate one language to another. Generative AI is so fluent and capable at it that it will get the job done for anything that isn’t critical. (critical meaning a faux pas would start a war or something) That profession is experiencing less demand and will need fewer people.
Software development as a profession is going to change radically. Marketing is going to change radically.
How soon?
That brings me to part 3.
Part 3: The Future Is Already Here
Constantine von Hoffman’s question about what the next 6-12 months holds for AI is, frankly, a giant question mark. There’s no way to know. We do know that huge models like Llama 4 are roughly midway through their training now, and probably will be released in the coming months. We know OpenAI is beginning testing on o3, their advanced reasoning model.
We know, thanks to agentic frameworks and reasoning models that prompt engineering is changing radically. The gap between someone incompetent with AI – “write me a blog post about marketing!” and highly skilled at AI is closing, fast, thanks in part due to reasoning models that automatically try to infer what your intentions are.
And we know there are significant architecture changes on the horizon as all the infrastructure around AI models changes and matures, from Google’s proposed Titan architecture to agentic RAG (document and knowledge retrieval, handled by AI autonomously).
The most mind-blowing technical capabilities of generative AI exist today, right now. They have, by and large, not been put to use yet. That’s what the next 6-12 months really holds – taking the capabilties we have today, and turning them into practical use cases.
A not so simple use case? Imagine adding a world-class trial lawyer to your bench when it’s your day in court. Your human lawyer is sitting with you there, and Gemini is listening, watching, and providing realtime feedback to your lawyer about what it’s seeing, what it’s thinking, and with Gemini’s grounding in search, even providing suggested strategies and tactics.
Imagine that same capability at your next quarterly board meeting. You sit at the table with the rest of the C-Suite as everyone delivers their updates and plans for the year. Gemini, primed and loaded with the world’s best corporate strategy knowledge, acts like a consultant. It listens to everything and provides you real-time feedback like suggestions, approaches, and cautions.
Imagine you’re at the doctor’s office. You’ve pre-loaded a secured Gemini instance with your existing healthcare data, and as your doctor reviews your records, Gemini does the same. It prompts you and the doctor to consider other possibilities – maybe that weird tingling sensation in your foot isn’t your imagination after all, and then a rank-ordered list of questions for you and your doctor to explore.
These scenarios may seem futuristic, but the technology to implement them is in market today. It’s not theoretical. It’s not sci-fi. It’s available to you right now, here, today.
Our job is to build it, to harness those powers.
In the next 6-12 months, the arms race among the big vendors will rage on, but for the rest of us, the race to use AI to create value is where the action really is.
Part 4: Your Next Steps to the Future
So all this is great. What do we do with it? What are the practical takeaways?
If you’re concerned about job loss, the time to learn AI is now. No matter what you’re currently doing with it, you could be doing more. I could be doing more. There’s so much possibility. So the first place you start is with a task and skills audit – for yourself, for your team, for your company. Shameless plug, my company, Trust Insights, does this. My business partner Katie is the absolute best at helping organizations understand their capabilities and deficits.
Second, once you’ve done your audit and you know where your weak spots are, you practice. You roll up your sleeves, dust off your keyboard, and sit down with the AI model of your choice to see how you could use AI to implement tasks within your weak areas and blind spots. Maybe you’re comfortable doing writing with generative AI, but not doing strategy and planning. Maybe you’re comfortable writing ad copy but not creating code. Whatever the blind spots are, use AI to mitigate them.
Third, you focus on the three MOST BESTS that I talk about in my keynotes. Whoever has the most best ideas, data, and brand will win in the AI era. You need to build your ideation muscles to figure out what’s possible and what’s profitable in your industry that AI can build for you.
You need to find all your data, public and private, put it into formats AI can recognize, and then start extracting real value from that data.
And finally, you need a strong brand, because in the era when we don’t need to ask search engines or social media for answers, the only way you’ll ever get recommended is if AI knows who you are. That comes from having a big, bold brand that shows up in training data and then in AI models.
If you do this, if you follow this process, you’ll be better positioned than 99% of your peers who have no idea what’s coming for them. The prospects for AI-resistant people are very, very dim. The prospects for AI-forward people are very, very bright. As a technology, it amplifies what’s already there. To paraphrase from the Captain America movie, it takes the good and makes it better, and it takes the bad and makes it worse.
If you’re good at what you do, it will make you better.

AI Use Case Walkthrough: Building Marketing Software Part 4
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Welcome back. This is where the rubber meets the road. We are at part four in our series on how to use generative AI to generate software. This is the AI use case walkthrough. In part one, we defined the requirements. I’ll go ahead and bring up my screen here. We did the requirements in part one. Let’s see if I can, it looks like it’s having issues here. Hang on for just a second, and there we go. So we worked on our requirements, this long, long list of functional and domain requirements for our software package, of all the things that it should do.
We’re making a game, a Wordle-style game. In part two, we worked out the best practices guide to tell the generative AI model how to be a good coder, to write the software, and you can see this is an extensive amount of information. In part three, we built the map of all the files that we were going to need AI to write code for. Now, I want to say this because I think this is important. At any point in this journey so far, you could stop and say, now I want to hand this off to an expert.
You could say after part one, after the requirements are done, you know what, this looks like a lot more work than I was expecting it to be. Hey, developer that I found on Upwork or Fiverr or wherever it is, you go to get developers, maybe it’s my friend’s at Global Source where I do some advising as a board member, hey, developer, here’s the requirements, here’s what we want to build. Can you build this? At the end of part two, you might say, hey, here’s the best practices guide that we think you should be using.
At the end of part three, you can say, here’s the architecture that we think this app should be at, and at any point along this journey, if you don’t want a code, or in this case, copy-paste code, you don’t have to. You can let someone else take over. I’m going through this process, A, because I just wanted to build this app, but B, to illustrate that, generative AI is very capable of doing this entire process, soup to nuts. That does not mean you have to do it. It just means that it can do it, but everything that you’ve seen so far are valuable things that you might want to add to your toolbox where you can say like, yeah, I would like to spec out the requirements for a tool or a service.
You could even use it to evaluate existing tools and services and say, hey, what are our requirements for a good SEO tool or for a good social media monitoring tool and follow the exact same process? So all of this is decomposable. You could take portions of it and use it in other contexts, and again, at any point, you can say, you know what, this is getting overwhelming, I want to stop, I want to have an expert takeover. I am going to live dangerously and not do that. Instead, I’m going to say, let’s get started.
So what I’m going to do, I’ve already taken the map and I’ve turned into all the necessary files. These are all empty files. There is not a single thing in this. There’s nothing in here. I’m going to bring up my VS Codium coding environment, and I got my list of empty files, and now one by one, we’re going to have generative AI write the code. So I’m going to start with saying, great, let’s get started writing the code to ensure completeness and adherence to the best practices and requirements, where should we start, and again, I’m asking it its advice, but where should I start?
Start with the server side, puzzle data handling endpoint. Why start here? It’s the data foundation, specific steps in order, server utilities, JS for a new server puzzles, JS. Okay, so I think this is that, I think that’s a great place to start. I am going to give it some additional directions, and the directions I’m going to give it is from my coding. What I’m going to say is, here’s a critically important instruction. As we improve code, always produce the complete code.
I say, we have no developers. We don’t have anybody who can work on this. It’s just me copying and pasting things, and so I’m giving it these instructions to say, I need you to do this this way. So with that, let’s go ahead and it says, start with the server. I’m going to go back into my project map, let’s expand out the window, and it says, start with server utilities. All right, great. Let’s start by having you produce server utils.js.
Now, again, we don’t want to have it just spit out the code. That is, generally speaking, that’s not how you want to have AI write code. You want to have it follow the same chain of thought that we did for building the requirements, for building the project map. Here is how to approach this task. First, state the functionality of the file and the requirements for it. Tell me what’s in it. Second, talk through how you will implement the functionality.
Third, explain your choices out loud of why you chose the implementation that you did in the second step. Fourth, produce the code in full. Always add a comment at the beginning and the end of the code with the files full path in the project. Let’s see, adhering to best practices and the requirements. So all we’re doing here, chain of thought, we’re giving it a manual chain of thought process. So we’re not saying, hey, just make the code. Let’s see what happens. We’re saying, no, no, tell me your plan.
What’s your plan? What are you going to do? How are you going to do this, and it’s going to say we’re going to create the server utilities JS file. This server will contain server-side function, utility functions. Its primary responsibility is to handle the logic related to puzzles, loading puzzles, and so on and so forth. Second, we’re going to use the FS system, the JSON, parse, so on and so forth. Why do I choose these things? Fourth, here’s the code. This is how you get great results out of AI.
Not by just saying make the thing, because that’s very naive, but tell me how you’re going to make the thing. I said in the previous episode, we were essentially kind of reusing an old saw from public speaking. In public speaking, there’s this old expression, tell them what you’re going to tell them, tell them, and then tell them what you told them, and that’s a fairly naive public speaking framework. There are better frameworks, Thames and Webster’s Red Thread is a great framework for that. However, for AI, that’s a great framework.
Tell me what you’re going to do. Tell me as though you did it. Tell me what you did and why and then do the thing, and that’s exactly what that process does. So here we have the server utilities. JS. I’m going to go to my disk and I’m going to open up server utilities. JS. I’m going to make sure that it will actually want all, all JS files to open VS Codium, and now I paste, and that’s it. So we’re going to do a little time-lapse here of me doing this because no one wants to watch this.
So let’s start the show. Okay, after quite some time of copy-pasting, which is all we’re doing here, copy-pasting, we have a completed folder of all of the code. So here’s all the code, and we can see, I, other than the favicon, there’s nothing here that’s zero bytes. So this is the first draft of the code. It is by no means done. I can already tell there are things missing from here. However, what we want to do is we want to have this thing evaluate what’s missing and sort of patch the holes.
So what we’re going to do is we’re going to have it do exactly that. I’m going to have it remember the requirements. So what I’m going to copy paste is this in here. I’m going to say, next, let’s review the requirements, and I’ll paste in our requirements, and then at the end of this, we’re going to give it some instructions, and the instructions we’re going to tell it are that we’re going to be evaluating this code to see if the code will actually work. I’m going to say our goal is to reach MVP, minimum viable product.
You’re going to evaluate in three steps, what it does well, what it does poorly, and what things, if any, are blocking MVP status. After you perform these steps, you’ll then integrate the changes. So our next step is to load in our code base, which I’m, what I did is I have a little utility that just takes all the text files in a directory and sews them together into one big file. We have the code base is not, this is not large. This is about, what, 4,000 words.
I don’t know how many lines of code it is, but it’s not many. So let’s see what it comes up with. Yep, several features are either incomplete or just placeholders, leaderboard logic, user authentication, database interaction, hints logic, game statistics, no input validation, styling, missing puzzle data. I knew there that piece was missing. What are the priorities, and here is a list of the priorities and how to fix them, high, medium, and low priority. So the next step to fix this is we would want to, we don’t want to have it try and fix each individual issue because many of these issues will span across files.
We’re going to borrow a page from Agile, and we’re going to say, we’re going to do vertical slicing instead. So using the MVP blockers, tell me what files are affected, and so it’s going to now review our MVP blockers and tell me exactly which files are problematic here. So high priority, here’s the server file, and here’s all the things that are missing in it for utilities or API and so on and so forth. So it’s going to spit out a long list of this stuff. What we’re going to do next is for repairing, we’re going to fix these things one step at a time, but first, we need the complete list of everything that’s wrong.
Okay, let’s go ahead and copy this. I’m going to copy this into our document here, and I’m going to say we’re going to, let’s start repairs. So let’s get repairs and upgrades underway. Let’s start with, I’m going to put a delimiter there and just going to chop out that first issue. Boom, that’s our, our first MVP blocker. Now we’re going to remind it, we’re going to remind it that we don’t have coders, so let’s not, we’re going to reuse that prompt, and we’re going to reuse a similar prompt as what we used to build the code which is, hey, tell me what you’re going to do, tell me how you’re going to do it, and then make sure you didn’t delete anything because one of the things that generative AI does when you’re asking it to code is it’ll fix something, and it’ll break something else, which is really stupid, but that’s the nature of the way the language models work.
So instead, you say, tell me what’s already in that file so that we don’t break anything. You’re going to now fix these issues. It’ll write the code, and then we force it to check it against original checklist. Did you, did you lose anything along the way? There we see now in the validation side. We remove the JSON-related code, migrate the get puzzle to use SQL Lite. Next available puzzle logic. No omitted code. Good. Update the get used for a ready. So now we can go back to our data file and patch that in.
So if you look, we went from that 65 lines of code for these utilities to about 95 lines of code. So we know that it identified a good number of things that were just not right. We’re going to move on to number two, and I’m going to, we’ll start the time lapse to go through this list because this is just a lot of copying and pasting, and no one needs to watch that for in real time. Okay, after extensive repairs, we’re ready to repeat this process. So remember, this is something that you want to do iteratively, want to have it review the code base and, and try to get us to MVP.
So the exact same things that we just did in what you can do in, in AI Studio that you can’t do in other forms of, um, AI, which is really nice is you can have it, uh, you can have it, you can remove stuff from the chat. So if I were to go through and delete all of the pieces that we’ve just done because they’re, they’re now incorporated, I could then reuse that earlier prompt. So I’m going to go ahead and delete all the older repairs that we’ve done, and you can see the token count on the window decreasing as we remove these pieces because this isn’t relevant anymore, right?
We’ve made the changes to the code. So let’s chop out all the old stuff, and now I’m going to remove the old tree and the old code. Right, there’s our requirements. Now we add in the new version of all this. Let’s make sure we have it up to date. Drop it in, and just to reinforce what we want to do, I’m going to copy and paste the prompt again. Okay, we’ve got our issues, and now, as before, we would specify our vertical slicing to have it tell us what files need to be patched and the changes need to make them.
Obviously, we’re not going to spend time watching this process. Again, you go through iterations of this, continuing to find and debug and clean. Now, at this point, once you’ve done this process and you’ve removed the MVP blockers, you’ve resolved it, you are essentially have an app that is ready to deploy. So in the last part, we’re going to talk about how to, how you bring this into production, how you, how you make this go long live, and what you might want to do with that.
But this is how you use generative AI to make software. There’s a few little odd things here and there that are unique to how I do stuff, and I should, I should be very clear. I am not a good coder. I am not a coder professionally full-time. I’m a data scientist. I’m an AI person. I am not a hardcore coder. So if you are a coder and you’re watching this and going, oh, no, that’s a, how you do it. Yeah, it’s probably not how you do it.
We tried as best as we could to accommodate that in part two, building the knowledge base about what best practices are for this kind of coding, with the understanding that, yeah, this is, this is how a non-technical person would use generative AI to create software. So that’s going to do for this episode. Thanks for tuning in. Talk to you on the next one. If you enjoyed this video, please hit the like button.

AI Use Case Walkthrough: Building Marketing Software Part 3
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Welcome back to our five-part series on using generative AI. This is an AI use case walkthrough to create software, to write software for us. As you will recall from parts one and two, we’re building a game. We’re building a Wordle-style game in languages that I don’t know how to code in. I don’t know how to code in these languages. I do know how to code generally, but we’re trying to do this with something I’ve never done before so that you can see the process for bringing something to life that is different than yet another ChatGPT-made blog post.
So in part three, we’re going to frame out the app, and what we’re going to do is we’re going to start by going into our Google, our AI. I’m using Google Gemini. Again, you can use ChatGPT or Claude. I recommend for the non-technical marketer who wants to do this kind of software building, use Claude. It’s by the best choice. I’m using Gemini within AI Studio. It’s my personal preference. As you recall, at the end of part two, we built that huge best practices guide for how to write code. This was all copy-paste, nothing, no actual coding has occurred.
In part one, we built the requirements. So I’m going to put in the requirements and ask the model to summarize it. Here’s why you do this. You put in the requirements and ask the model to summarize because it, A, it loads all the requirements into its knowledge, and B, it reinforces the most important parts. So I’m going to start by saying, today we’re going to get started framing out my app. Here are the requirements. Do not code yet. Read the requirements and summarize them at a high level. Now, I’ve pasted in my huge requirements document and I’m going to add the role statement.
Technically, probably I don’t need to because between the system instructions and the, and, and, and all of the, the, the requirements document, there’s enough information that it will invoke intelligently what you’re supposed to do. However, we’ll add it in for best practices just to stick to the Trust Insights RAPPL framework: role, action, prime, prompt, evaluate, learn. So the role is you’re an expert Node.js and React.js coder who specializes in web-based game development. That’s our role. The action, we’re going to get started on this, here the requirements.
This whole section and what’s in the system instructions, this is part of priming. So we’re going to prime the model. You can see by putting in the requirements document and the system instructions, we’re already at 12,000 tokens, which is 8,000 words. So we have super primed this model to do this specific task. You would never, ever do this by just saying, hey, let’s write an app. It would be, it would go terribly, but by having all the information in parts one and two in place, we’re going to get great results off the bat.
It says, let’s break down the requirements for the emoji puzzle game. High-level summary based on it. All right, now I’m going to say, let’s go ahead and start framing out the file structure for this app, and then as a developer, we want to keep this as lightweight as possible, as skinny, as few files as necessary, while still adhering to best practices. Here’s how to approach the task of framing out the app. First, I think for this, what I want to do is I want to have it using some really good in-depth chain of thought.
I want to think through its steps, not just giving me the answer. I want to evaluate itself and think about that stuff. So I’m going to say, evaluate my instructions and explain aloud what the intent is and what the task is. Second, from all the information I’ve provided and your own background knowledge of Node, React, SQLite, and HTML5, CSS, and general programming, best practices, select and list out loud the specific knowledge you’ll need to accomplish this task. This is more chain of thought, getting it to think aloud.
Third, explain your approach to solving this task of mapping out the architecture of our app. What are you going to do? Why did you make the choices you made? How will you build the architecture map? Fourth, build the complete, comprehensive, final architecture map for our game. So this is a form of structured chain of thought, where we’re saying, tell me what the task is, tell me how you’re going to think about the task, tell me what you’re going to do, then do the thing. You may have seen on LinkedIn recently.
I talked about the old public speaker saw, tell them what you’re going to tell them, tell it to them, tell them what you told them. That cliche from public speaking, we’re kind of doing the same thing with AI, and unlike public speaking, this actually works really well with AI, by saying, tell me what you’re going to do, tell me as though you’re doing it, tell me what you did, and then do the thing. So here we have, ooh, this is going to be a big, beefy one. So we got understanding the intent and the task, which is saying that we’re going to skeletal file structure.
Here’s the relevant knowledge. Here’s I’m going to do the task, why these choices, separation of concerns, React best practices, Node.js organization, lightweight and scalable. Here is the app and we have a client and we have a server, and so this is going to be the app. That’s a lot of code. That is going to be a lot of code. So we’re going to be spending some time on this. Did you know that this is going to be this complex? I didn’t think that making a Wordle-style game would be this complex. I’m going to ask about this.
Is this as skinny and efficient as possible? It seems quite large. Explain why. It says you’re right to question the structure. It follows best practices. It might appear a bit large for a project that aims to be as skinny and as efficient as possible. Here’s why it looks that way. Best practices and conventions for React and Node practices, maintenance, scalability, anticipation of growth, clear separation of concerns. How you could potentially slim it down. We can defer the context, simplify server models.
Here’s a revised more compact file structure. See, this looks a little bit better to me. This is much more of the kind things, this potential for less organization, slightly reduced scalability. I’m okay with this. So I’m going to take this whole thing here and I’m going to go into my prompt library, and I am going to save this. So this is going to be our project map. Now we’re going to say is, great, for our revised project map, add comments to each line on the map explaining what that file’s core functionality is.
So we want to, well, it won’t just want a list of files. We want the list of files plus what is supposed to do. Again, the more verbose an AI model is the better it’s going to perform, the more focused it will be, the fewer mistakes it’s going to make. So you can see here on screen, it is now spitting out a very nice map with explanations of what each thing does. So this is going to go right in our documentation as our project map. So this is part three, framing out the app. If you think about this, we’re going to need to code this.
We’re going to need to code this in part four, but by having the requirements, by having the best practices, by having the map, we are in a position where we can start to actually build this app and make it work and hopefully work very, very quickly. So that’s going to do it for this episode in this whole process of building out our own software using generative AI. I think it’s important to point out the final product is not going to be AI. The final product is going to be a classical piece of software. What makes this cool for generative AI is this gives us capabilities that we otherwise might not have.
I can’t code, and I don’t know how to code in JavaScript. I don’t know React. I don’t know Node. I can copy and paste like crazy. I don’t know these things, and yet this puts those skills within reach for me as long as I know what to ask for and how to direct essentially the intern, the coding intern is to what I want the coding intern to do. So, that’s episode three in the series. Stay tuned for part four where we start building this sucker. If you enjoyed this video, please hit the like button.

AI Use Case Walkthrough: Building Marketing Software Part 2
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
This is part two in our series of an AI use case walkthrough, building software for the non-technical person like the marketer. In part one, we did the requirements gathering for our app to walk through all the considerations that we would need to build this app. As a reminder, we’re building kind of a fun puzzle game. So in part two, we’re going to pick up where we left off with library construction. I’m using Google’s Gemini in AI Studio, but again, you’re free to use the AI tool of your choice, ChatGPT.
I would say for the average non-technical marketer, your best tool of choice would probably be Anthropic’s Claude because it’s really good at coding. If you’re going to be building a big app, then probably you’re going to use Google Gemini because it has the largest working memory. Today, we’re going to start building the library construction, and what we’re specifically talking about here is building the best practices documents, the knowledge blocks like we saw in part one for the code. This is important because we want to specify what are really good best practices for writing this kind of software, and then when we start writing it, the AI model will have those guidelines to follow, things like error tracking and logging and stuff like that.
To do this, we’re going to use the Trust Insights RAPPL framework: role, action, prime, prompt, evaluate, and learn, as we did in the previous steps. So let’s go ahead and go into, I’m going to pick up where we left off. We’ve already done the requirements gathering. What I want to say, do next is I need to know what kind of best practices library to work with. So far in this app, we are already almost 18,000 tokens, which is what, about 14,000 words in. I’m going to start by saying, what are the best technologies, libraries, frameworks, and languages best suited to meet our requirements for developing this app?
As you recall from the previous one, I’m going to save those requirements as markdown. When you do this and you save it in your prompt library, you can see that you get a really, really nice extensive list of this. This is what the thing is going to do. The author here is going to be Gemini and Trust Insights. Boy, do you think it’s October 26, 2023? It is not. This is January 12, 2025. That tells you where the knowledge cutoff of this thing is. All right. So this is my, in my prompt library now, I’ve stored the requirements for this app. Now I’m going to ask it, what technologies are the best fit for this?
We’re going to ask this question, get the answer, answers and then build out the best practices library. Client-side HTML5, CSS, JavaScript, framework React for the user interface, Emoji Picker for React, UI components, Material. Let’s see, server-side Node.js for this minimal service, I component, framework Express.js, SQLite for the database, and JSON for the puzzles, and NPM or Yarn for managing project dependencies, Webpack or Parcel, hosting, Vercel, AWS, Netlify. I’m just going to stick out on my website. Analytics, GA4. Testing, React Testing Library.
So these are all the potential technologies. It says the stack summary, React and so on and so forth. Say, great, we are going to standardize on the React Node approach given the choices. Show me now the revised tech stack. We’re going to use React, Node, SQLite. So that is front-end, back-end, and database. So now we get a much more focused list of all the things that we’re going to be doing. Now our next step is to start building out our best practices for these languages.
We’re going to start by saying, next, let’s do the role. You are an expert JavaScript developer skilled in Node, React, and web-based application development. Today, we’re going to isolate best practices for coding in React and Node and Node. What do you know about general best practices for creating robust, high-performance, high-speed, resource-efficient code in React and Node specific to web-based entertainment applications? So really what I’m doing here is I am just parroting back what the tool set or are a tool choices of saying, hey, what do you think, what are the best practices here?
What we’re going to be doing is we’re going to distill this down as we did in part one of taking all these ideas and things that typically go wrong and expert tips and tricks for both React and Node into a guide, into a knowledge block. So it’s spitting out that now. So I’m going to say, what are common mistakes in React and Node for web-based games that less skilled developers often make? I’m going to wait on this because I want to take this section here, and I’m going to put this in my comprehensive best practices guide instead of having it summarized because I don’t want to lose any of this valuable information.
I’m going to just copy and paste all three chunks. Note that we’re not coding. There’s zero coding happening here. This is literally just copying and pasting, but we’re asking questions to have the model spit out its known best practices for these languages. If I wanted you, I could take maybe the documentation from the React website or the Node.js website and actually feed that in as training data for this as well. That would be a way to get at even more great ideas. So I’m going to put in the React best practices and the Node best practices, and now I’m going to ask that second follow-up question.
We’re going to let it talk, and then we’re going to, while it’s talking, we’re going to write the third prompt which is, what are some expert tips and tricks in React and Node for web-based games, tricks of the trade, uncommon knowledge and approaches that we have not discussed yet? Okay, so it’s coming up with our our things to avoid guide. All right. So it has spit out the things to avoid guide. I’m now going to copy that, put that in my prompt library. You’ll see here, I’m going to just put some headings in to make this a little easier to see.
So there’s our best practices for in general. Here are our mistakes to avoid, and then we’re going to have React and Node game development, expert tips and tricks. Let’s see how we’re doing over here. Still coming up with things. All right. Our tips and tricks are done. So now we’re going to copy that, go to my prompt library, paste that right in, trim out a little bit of the the fluffy narrative. What do we have? We have a gigantic set of best practices for this exact application. Now, here’s the question, what do you do with this?
Well, what we do with this is we use this as system instructions. So in Claude, you could use system instructions. In ChatGPT, you can use it as system instructions, and of course in Gemini, you can do the same thing. I’m going to create a new prompt now, and I’m going to take that big, huge document that I just did, and I’m going to put the entire thing in. That is about 5,000 words of best practices, but what we’ve done is we’ve preloaded our AI to now be an expert coder in this whole setup.
So what we’ve done in part two here is we have taken our, we’ve used generative AI to take our overall requirements and then build from those requirements our instructions for telling this model how it’s going to code, how it should code, the things that it should not do. So this is part two. Next, in part three, we’re going to start framing out the application to understand just how complicated this is going to get. In part four, we’re going to start building it, and then in part five, we’re going to talk about deploying it.

AI Use Case Walkthrough: Building Marketing Software Part 1
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In this five-part series, we’re going to be talking about a very specific AI use case for generative AI, using the latest and greatest models in an application that AI is really good at. That application—and bear with me marketers, I know because there’s a lot of folks who are marketing folks—the application is coding. We’re going to write some code using generative AI. Now, you might say, okay, wait, wait, wait, I’m a marketer. I’m out. I don’t code. I don’t write code. You kind of do, and more important, you may want to. Here’s why. What does generative AI really let us do? It lets us make stuff. It lets us make a lot of stuff. We can make blog posts and newsletters and e-books. At a certain point, we’ve got way more stuff than we have time to consume.
So, of course, what’s the solution? What do people do? They use AI to summarize the stuff. Oh, here’s another long email, hit summarize. Here’s this, hit summarize. What was all that effort for to make stuff that no one reads? How do you get around this? How do we capture people’s attention? The answer is to make things that defy summarization, things, obviously interactive things to some degree like video, but more importantly, things that are engaging, that are that are interactive, true interactive, like software. There are so many software languages and tools and capabilities, and AI is really, really good at writing computer language.
Here’s why, unlike verbal language or written language, computer programming languages are very, very unforgiving. They’re very absolute. If you indent wrong or miss a semicolon or something, the software just doesn’t run. There’s running and not running software. You could have a blog post with maybe some inaccuracies or whatever, but the end user can read the blog post and go, okay, I understand what we’re trying to do there. Software does not work that way. Software either is correct or incorrect, and AI models have consumed so much of it that they’re really good at constructing it.
So in this five-part series, we’re going to go through how a marketer, you and me, might want to build an application, a piece of software to maybe do our own jobs better or to provide some form of interactive content for our audience that they might like, they might want to spend time with, they might want to give attention to, whereas yet another blog post that no one reads isn’t the best use of our time. We’re going to cover five things: requirements gathering, library construction, framing out our app, building the app with generative AI, and then deploying the app. Today is part one, requirements gathering. Requirements gathering is just saying, what do we want this thing to do, and what is it going to be needed to make it happen. Requirements gathering really is, it’s asking ourselves all the questions.
What language should we use? How are we going to use this thing? What kind of vision do we have for this? The most important part of this process is the part that you can’t do with AI, and that is what’s the idea? What is it that you might find fun? What is it that you might find entertaining or interesting that you’d want to build? AI can certainly help you brainstorm, but it can’t just give you the idea. You can’t say, I want an interactive app that people will like. That’s super vague. I’ve had in my mind this idea of a game kind of like Wordle, but where the clues, it’s kind of like a crossword puzzle too, where you have to guess the answer, but using emoji.
I thought that would be a good example of how we would do this. So let’s go ahead and start part one, requirements gathering. I’m going to use Google’s AI Studio. You can use, I would say, for the average marketer building a small app, the best tool to use would be Anthropic’s Claude. I’m using AI Studio because I have a feeling this thing’s going to get kind of unwieldy, and it could potentially get beyond what Claude’s context window, it’s what it’s active memory could actually hold. So I’m going to use Google’s Gemini, and I’m going to use the latest version of the model in AI Studio.
The first part we’re going to start is we’re going to use the Trust Insights RAPPL framework: Role, Action, Prime, Prompt, Evaluate, Learn. We’re going to use this in multiple iterations throughout this process. So the first part is we need to do requirements gathering. I’m going to say you are an award-winning software developer who specializes in interactive online experiences such as web-based games and amusements. Today we’re going to build the requirements for an idea I have for a game. First, what do you know about the best practices for requirements gathering?
We’re going to let the model talk. This is the role, action, and prime step of the first part of the prime step with the RAPPL framework. What we’re going to try and do here is we want the model to essentially tell us how to do this. So here’s it’s going to spend a whole bunch of time just talking out loud about here’s what I think good requirements gathering is. The second question in prime is, what are common mistakes in requirements gathering that less experienced developers often make?
After it finishes its first level of output here, we’re going to ask it the exact same thing again. So what are the common mistakes made? As it answers that, I’m going to ask for a third one. I’m going to say, what are expert tips and tricks for game interactive web-based game development requirements gathering that we haven’t talked about yet? All right, so let’s see. We got analytics from the start. Yeah, yeah, yeah. Gameify the requirements gathering process. Now we’re going to do one more here.
I’m going to say using everything we’ve discussed so far, from best practices to mistakes to expert tricks of the trade, build a complete, comprehensive, best practices outline in detail for requirements gathering for web-based interactive games. So this is just a summarization step where we’re going to take all of this knowledge, and we’re going to preserve this. This is what I like to call a knowledge block. This chunk of text here is something that you could use in future prompts. In fact, we’re going to do several of these at a certain point.
This first part is just getting all of the pieces together so that if we need to do this again, we can reuse this. So I’m going to go ahead and save this. In my knowledge blocks, I would call this web-based game development knowledge block, and in your prompt library, whatever the prompt library software is that you use, you want to save these knowledge blocks. You want to save this knowledge, and every time a new model comes out, like Gemini 2, which is what we’re using now, you would want to follow this process and regenerate the knowledge in case there’s new knowledge, particularly about topics that are rapidly changing.
Best practices for requirements gathering, that doesn’t have changed a whole lot in the last 50 years for web-based stuff and interact is obviously the specifics, but the general best practices for requirements gathering isn’t too different. However, if you’re doing something say like virology, this would be significantly different. So we’re going to go ahead and copy and save that. I’ll put that in my prompt library, and now we’re actually ready to start the requirements gathering process and say great, we’re saying like that.
Let’s start the requirements gathering process. I’m going to give you information and ideas, and I’ll ask you to ask me questions so we can develop a complete set of requirements. Now I’m going to take a few minutes here and just sort of write out what I want this game to do. I’m not going to read out loud and type as it’s not a good use of our time. Okay, we’ve started. We’ve said let’s start the requirements gathering process. I’m going to give you information and ideas. I’ll ask you to ask me questions so we can develop a complete set of requirements.
The game I want to make is kind like Wordle and kind of like a crossword puzzle. It’s going to offer clues in regular language, but the answers will all be five character emoji answers. For example, if the clue is a place you go to enjoy the sun on the beach, the answer might be the Bahamas, and the five character emoji answer would be those five emoji. The game will be interactive on a website, run entirely client side, use Google Analytics 4, all this stuff. These are all the things that I thought of as I was typing out what I would want the game to do.
I ended after several paragraphs saying, given all this, let’s start framing out requirements. What questions do you have? You can see there’s quite a lot of requirements and stuff on screen. Obviously, I have a pretty good idea of what I want. You could start with, I just have this idea for a game. What should I do? How should I approach this and things like that? I’ve given this some thought, so this is this is probably the heavy lifting part is just coming up with what is the idea at all, and then how do we make the thing?
What are the requirements you would need? So it’s coming out and saying, okay, this is a fun thing. Core gameplay and puzzle design. You mentioned five character emoji answers. Are they strictly five individuals? Could include sequences where the multiple emojis combine to one visual representations, e.g. country flags, which technically used multiple characters. How you handle emojis that are might be interpreted differently among across platforms and devices? Some may look different on iOS and or different web browsers.
Would be a standardized set you’ll test against? Was the range of acceptable emojis anything in the Unicode standard, or allow for variations? Clue structure, answer input. What we’ve got here is a long series of questions. So what I would what I would do at this point, what I will do at this point is take all this stuff, put it into a text document, and start answering these questions because this is going to to be a lot of work. Now what I could do, and what I might do is instead of sitting here and typing all this out, I might open my voice app and talk this through and see if I can give the answers that way.
That might be a slightly more efficient way of doing that. So I’m going to go ahead and take a few minutes to answer all these questions. All right, so I have taken 10 minutes to answer all of the questions. I’m going to drop in my transcript of this from my voice memos app. I’m going to say, here are my answers to your questions, and we’re going to let it process and read through it all. Hopefully, that says, okay, great, you’ve given me a lot of helpful information. Let’s break down your answers.
Good, it’s summarizing everything that I put in that 10 minutes, which is probably what, 1,500 words of typing, and yep, those are all my answers. Looks good. Okay, now let’s see if it comes up with any additional questions. I think I gave it pretty solid answers. Here are some areas. We’ll provide specific recommendations. Emoji handling, I’ll research and suggest a set of emojis. Input validation, accessibility, rating system, emoji obscurity. We got more questions to answer here. Let’s see.
Oh no, those questions is going to ask itself, and I’ll take the information and start drafting a formal requirements document incorporating these answers in my initial recommendations. Great, please produce a complete functional and domain requirements document according to best practices that will guide our development. So now we’re at the end of the first part of this where we are having the tool build out the requirements. Note that this has taken almost an hour of time just to think through essentially what the software is, because some of the things that can go wrong with it, some of the considerations that we didn’t have, but by using the RAPPL framework and having it build this stuff, doing the evaluations and things, we are well on our way towards building a really good app.
We can see here we’ve got requirements coming up. So we have, oh, look at this, this is beautiful. Introduction, goals, target audience, player personas, user stories. Oh, look at this, my CEO and partner, Katie, is going to love this, building out user stories right in the requirements. Functional requirements for the game, user accounts, profiles, the leaderboard. This is the kind of document that you would hand off to any developer. You would say, hey, developer, here’s what we’ve got to create. Now start the process of planning how you’re going to develop this app, which is just wonderful.
One of the things I was thinking about as I was talking about this, because the game initially was, I had the idea, is just be a fun, silly little thing. When you go through the requirements gathering process and you have a partner that asks all these great questions, it’s like, hmm, this might be a more complicated project than I thought. So that’s going to do it for this episode. In part two, we’re going to talk about library construction for the building, starting to build the code, so stay tuned for that. I’ll talk to you on the next one.

What’s On My Mind: A Semi-Technical Deep Dive into AI Language Models
This week, let’s do a very deep dive into the technical guts of generative AI, specifically large language models. To make AI work optimally, it helps to understand at least a few of the concepts, so we understand why they do what they do.
Part 1: Tokens
Generative AI begins with tokens. LOL already with the technobabble.
What’s a token? It’s a unit of information that the AI uses to learn and generate text. Think of it like ingredients in a recipe. If you want to understand how to make a cake, you need to know what goes into it: flour, sugar, eggs, and so on. Similarly, to understand language, AI needs to break it down into its basic components: tokens.
Now, you might think that the simplest way to break down a word is into individual letters, like s-t-r-a-w-b-e-r-r-y. That’s called character-level tokenization. But for large language models, that’s like chopping your cake ingredients into individual molecules. It’s too granular, and it makes it hard for the AI to see the bigger picture. Imagine trying to figure out how to combine different molecules of flour, sugar, butter, etc., to make a cake. It would be very difficult, as there are so many combinations.
On the other hand, you could just treat each whole word as a single ingredient, like “strawberry.” That’s called word-level tokenization. But that’s like having a separate ingredient for every possible cake variation: strawberry cake, chocolate strawberry cake, gluten-free strawberry cake. You’d end up with a gigantic recipe book, and you’d have trouble with new types of cake you’ve never seen before, also known as out-of-vocabulary words. What if someone asked for a “strawberry-rhubarb” cake and that wasn’t in your recipe book?
So, AI model makers use something in between, called subword tokenization. It’s like having ingredients for common parts of cakes, like “straw,” “berry,” “chocolate,” and “cake.” This way, the AI can handle words it’s never seen before by breaking them down into familiar parts. The most common type of subword tokenization is called Byte Pair Encoding, or BPE for short. Another popular one is called WordPiece. These algorithms are a bit like a master chef who knows how to combine ingredients in the most efficient way. They look at massive amounts of text and figure out the best way to split words into subword units. These algorithms also help keep the vocabulary, or all the possible ingredients an AI can use, to a manageable size.
For example, using BPE or WordPiece, the word “strawberry” might be split into “straw” and “berry.” Or it might stay as a single token if it’s used very often. It all depends on how often different combinations of letters appear in the text the AI learns from.
This is why, by the way, AI often has trouble telling you how many Rs are in the word “strawberry”. You might think it’s because “strawberry” is chopped up into “straw” and “berry” but that’s not quite right. It’s more like asking a chef to tell you how many molecules of carbon are in a cake. They could probably figure it out, but that’s not really what they’re trained to do. Similarly, AI models are trained to understand and generate language based on the relationships between tokens, not to count individual letters. They see the cake, or in this case the word, as a whole, delicious thing, not a collection of individual atoms.
Who wants cake now?
Why go through all this trouble? Because tokens are the fundamental building blocks of language for AI. By breaking down text into tokens, AI can start to understand the relationships between words and how they fit together to create meaning. Each token will be assigned a number.
Part 2: Vectors and Embeddings
Once a model maker tokenizes a text, converting every word and bit of punctuation into numbers, they then have to convert those numbers into vectors and embeddings.
Think of it like this: imagine a special app called “Google Language Maps.” In this app, every word is a location on the map, and its meaning is determined by its coordinates, just like latitude and longitude in the real Google Maps. If you search for “Starbucks” in Google Language Maps, what do you expect to find nearby? Probably other coffee shops, maybe a few tea places, perhaps some bakeries. You have an intuitive sense of what locations are close to “Starbucks” on this language map.
Imagine the area around “Starbucks” in Google Language Maps. What are all the other points of interest (POIs) that might be close by? When AI model makers make models, they take all those tokens and plot them on a giant, multi-dimensional map, kind of like the one in Google Language Maps. Words with similar meanings, like different coffee shops, end up close to each other. Each word is assigned a set of coordinates, called an embedding, which tells the model exactly where it is on the map.
Now, here’s where it gets interesting. Just like Google Maps can adjust your route based on traffic, the meaning of a word can change depending on the context. So in our Google Language Maps app, if you have a paragraph talking about things like jasmine, oolong, or matcha, and then you type Starbucks a paragraph later, the AI model is more likely to suggest the word tea than coffee. Even though the word coffee is most strongly associated with Starbucks, the words jasmine, oolong, and matcha are more related to tea. So, in this case, it’s like Google Language Maps rerouting you. Even though your usual route to “Starbucks” might pass by a bunch of coffee shops, if the context is all about tea, the model will adjust the “route” to “Starbucks,” making “tea” the closer and more relevant destination. It will calculate a slightly different route, or a slightly different set of coordinates, for that particular instance of Starbucks.
Conceptually, if you think about every word having a location on this giant Google Language Map, and how those locations can be adjusted slightly by the surrounding words, like a route being adjusted, then you’re starting to get a general idea of what vectors and embeddings are. Embeddings are a numerical way of representing where words are located on the map and how they relate to each other. It’s like the coordinates and distances that Google Language Maps uses to calculate the best “route” between two words. Those relationships, those coordinates and distances, are what allow large language models to understand and generate human language.
It’s worth pointing out here that this process, vectorization and embedding, is why generative AI can’t do math. Mathematics – computing operations like addition, subtraction, multiplication, division, and all forms of calculation – don’t operate based on what numbers are nearby. Asking generative AI to do math is like asking a blender to fry a steak, or asking for sushi at a Starbucks. That’s just not what it does. Now that you know how vectorization and embedding work, conceptually, you can see why generative AI language models shouldn’t be doing math.
Part 3: The Attention Mechanism
Now, let’s move onto the heart and soul of today’s generative AI: the attention mechanism. Introduced in 2017 by researchers at Google, the attention mechanism is a novel way of predicting tokens. For us marketers, most of the time, that’s words.
Prior to 2017, there were plenty of ways that machines tried to predict words. You’ve enjoyed that experience for years, with autocomplete on your phone and similar predictive mechanisms. These older models had a very narrow, very incomplete memory that relied on different techniques than the attention mechanism, meaning they would successfully predict words you used frequently and recently (mostly, lots of people still find their phones autocorrect to ”duck this ship”) but they couldn’t “remember” or process more than a couple of words back.
The attention mechanism is different. It allows the model to consider a large amount of text when making predictions, not just the few words immediately preceding. From the very first word you type to what the AI says, every word that appears on screen can be taken into account. Modern AI like Google Gemini can remember up to 2 million tokens, or about 1.5 million words, in a conversation.
Let me say that again because it’s really, really important.
Every word that appears on screen can be taken into account when the AI is predicting the next word. But, not every word is equally important. The attention mechanism allows the model to decide which words are most relevant to the prediction it’s making right now.
Here’s an example of how this works. If you’re old enough, you probably remember a series of kids’ books called Choose Your Own Adventure. In those books, you’d start out at the very beginning, and you’d choose the next page to go to based on the story you wanted to read. Each page would have multiple choices, and that would eventually end up telling a complete story. And you could go back, re-read, and make different choices and end up reading a functionally different story.
That’s kind of how attention models work, but with an important difference. Instead of choosing a whole page, the model predicts one token (usually a word or part of a word) at a time. Think of each token as a single plot point in our story. The attention mechanism helps the model decide which previous plot points (or tokens) are most important for predicting the next one. Every choice, every prediction, influences the next choice, and those choices are cumulative, just like in a Choose Your Own Adventure book. Instead of predicting every page of the story, the attention model is choosing a new token at the end of every previous one, assembling the story bit by bit instead of page by page.
This is critically different than older forms of AI because the attention mechanism can remember (something called a context window) a ton of information. Modern AI like Google Gemini can remember up to 2 million tokens, or about 1.5 million words, in a conversation. What you write at the beginning of the chat influences the words being predicted a hundred thousand words later.
This is also why being specific with our language matters so much. The more irrelevant words or junk we put into a chat with AI, the more those words throw off future predictions, making them less accurate. It’s like trying to force plot points into our story that don’t quite fit.
This is ALSO why generative AI, when naively prompted, tends to spit out boring, uninspiring slop. It’s predicting based on a very general set of plot points and thus guessing the most probable next words with no additional guidance. Highly probable text is generally not highly exciting text to read, nor is it unique.
Something I say in my keynote talks is that the more relevant, specific words (especially jargon) you use in prompts, the better AI will perform. It’s like giving the model more interesting and specific plot points to work with. It’s why so many prompting frameworks ask you to be specific and verbose.
Here’s another general rule of thumb, now that you understand the attention mechanism. Remember that every word on screen can influence the next prediction, but some words have more influence than others. If you ask a generative AI model what it knows about a topic and get it to respond with correct knowledge, then the next prompt you type will take into account all that background information you invoked, making the results better. You’re essentially providing more relevant plot points for the model to consider.
The more AI has a chance to talk, to step through things, to go step by step, bit by bit, the better it tends to perform. When we look at prompt engineering as a discipline, more than half of the techniques are in the chain of thought family, which is fancy for “talk this out step by step”. This works because of the attention mechanism – the more a model talks, the more relevant words go into the context window, increasing the accuracy of predicting the next word. Each step provides more plot points, making the overall story more coherent and detailed.
Part 4: Putting the Pieces Together
With everything we’ve discussed so far, let’s start putting together the big picture so you can take practical steps towards improving your AI usage.
What we’ve covered so far: models are made from training data, turned into tokens which are then turned into statistical relationships of words, phrases, topics, and concepts. Generally speaking, a model will return results that are statistically close to what we prompt it with.
Thus, if we want to get the most out of generative AI, we have to understand that these distributions, these statistical relationships, are how models make decisions. If we don’t like the decisions they’re making, we need to change how it makes those decisions. We do that with lots of specific directions, examples, asking it to think aloud, asking it to go step by step, and giving it guidance.
Role: telling the model who it is with specifics and jargon. This invokes statistically related terms, and the more jargon, the better. The more specific, the better, because the model will match up our role statements with information it’s seen in the past.
Action: telling the model at a high level what task you want it to perform. This helps guide the overall output by introducing the goal early on. We won’t necessarily provide a lot of detail here, but we want to set the goal down early to steer and influence future predictions.
Prime: telling the model to spit out what it knows on a topic, or uploading our own data here if we have very specific information we want the model to use. This background information fills the model’s memory with lots of relevant words and concepts, helping further reinforce the direction we want it to go. Imagine in the Choose Your Own Adventure book instead of a short introductory paragraph before the first decision, you provide, like, a 40 page story. By the time the reader has read through that story, they have much more information to make the next choice with.
Prompt: telling the model what to do. This is the actual prompt, the instructions for what we want the model to do. By this point, the model’s working memory is so full of knowledge that even a relatively generic prompt like “Now write an article about B2B marketing best practices” will deliver great results because we’ve spent a lot of time loading up the model with that knowledge.
Evaluate: telling the model what it did well or wrong. This step helps correct the model’s outputs and refine them.
Learn: telling the model to build system instructions or prompts from the conversation. We use the attention mechanism and the context window to distill down the most important parts of the conversation into a prompt we can reuse for the next time we need to accomplish the task.
Behind the scenes, the RAPPEL framework is using a bunch of well-researched techniques from a variety of academic papers I’ve read on prompt engineering, and taking into account the underlying mechanisms of the attention mechanism and the way generative AI works.
For example, the role is a technique called role prompting. Consider two articles, one written by an expert and one written by a drunk on Reddit. With a naive prompt like “write a blog post on email marketing”, a model would look into its long term memory and find all the associations with those words – including both sources. When models are made, there’s no weighting to say “this academic paper should be given greater consideration than the drunk dude’s Reddit shitposts”. The text is weighted based on volume, not authority.
The action and prompt are a technique called reinforcement prompting. The more you repeat specific instructions, the more weight they’re given in the attention mechanism. Repeating key instructions essentially doubles the number of tokens about that instruction, tilting the model towards what you want it to do.
The priming step is a technique called generated knowledge prompting, especially when you ask a model what it knows about a topic. This technique fills the context window with large amounts of relevant text.
The entire framework is also a form of chain of thought. By going through all these steps, piece by piece, we are giving the model a chance to invoke relevant tokens at scale, increasing accuracy.
Let’s look at an example. A naive prompt that will generate lackluster results might be something like “Let’s write a 500 word blog post about the importance of influencer marketing strategy in B2B marketing.” Based on the knowledge we’ve talked about so far, why will this prompt deliver subpar results?
The purpose of a piece of content like this is to educate, but in the process also add value. We do that by taking a unique perspective on things. This prompt has so little information in it that what the model will return in its embeddings is the most common, highest probability information – and that won’t be unique.
So how do we uplevel it? Let’s start with the role:
Role: You’re a Content Marketing Institute award winning content creator. You specialize in influencer marketing, especially B2B influencer marketing, like field experts such as world famous Onalytica CEO Ashley Zeckman. You know influencer marketing, influencer identification, influencer analytics, and influencer strategy for B2B marketing in B2B industries.
Action: Today we’ll be writing a 500 word blog post about the importance of influencer marketing strategy in B2B marketing. Before we begin, let’s set the stage.
Prime: What do you know about the topic of B2B influencer marketing strategy? What are common mistakes made by less experienced B2B marketers? What are expert tips and tricks you know to maximize your B2B influencer marketing strategy?
Now we let the model talk. We let the model fill in the context window with its knowledge, and we provide corrections if needed. If we don’t see anything unique, we may need to do additional priming. For example, we might continue priming with:
“You’re speaking at MarketingProfs B2B Forum about B2B influencer marketing strategy. In the back of the audience is an aggressive, assertive, loud, blunt heckler who takes a contrary position on everything you’re saying. What are they saying, and what rebuttals do you give for their points?”
This priming step is a technique called contrastive prompting (combined with role prompting), designed to invoke different, lower probability tokens by taking a contrarian perspective. Let the model talk.
You could even continue this chain of conversation for additional turns:
“The heckler gets louder. Now they’re pressing you on valid criticisms of influencer marketing that we haven’t talked about yet. What are they saying? What rebuttals do you have?”
– Prompt: Considering everything we’ve talked about so far – best practices, mistakes, expert tips, the heckler’s points and your rebuttals, draft the outline for the article. We’re aiming for a unique point of view, an uncommon take on B2B influencer marketing strategy, so dig deep into the points we’ve made in the conversation so far. Produce the outline, and explain your thinking for each part of the outline — how it’s unique and uncommon, and how it will provoke new thinking in the reader. – Evaluate: at this stage, we evaluate the model’s responses, asking it to clarify, to improve, or to change directions. Remember that the attention mechanism takes into account everything that’s been said so far, so telling it to “forget previous information” tends not to be as effective as it might be with a human. You’ll also finalize the process – once you’re happy with the outline, have the model write the article. – Learn: Considering the entire process we used to write this article, create system instructions for a large language model (LLM) like Google Gemini to replicate the process. The user will provide a topic or a draft and the intended audience. You will list out best practices, common mistakes, tips and tricks, and then role play an antagonistic heckler as well as a seasoned expert to rebut the heckler. After conducting this process step by step, draft an outline for the user to review and approve. Then once the user approves, write the article. First, decide which prompt engineering techniques to use. Then explain why those techniques. Then generate the system instructions.
What you’ll get out of the final stage in the RAPPEL framework is reusable code, a prompt you can reuse for the next time you conduct the process, optimized for the model you’re working with.
Part 5: Wrapping Up
This was a very long tour through the inner workings of AI, in a way that hopefully made the very, very technical stuff accessible. We expressly didn’t cover the detailed mathematics and statistics because knowing those bits doesn’t lend a lot of usable information for how to use AI better, like query and key value caches, dot products, softmax layers, etc.
The reason I wanted to dig into the technicals like this is to help you understand not just what a prompting framework does, but why. When you understand the mechanics of AI, you can more clearly evaluate whether a “ChatGPT hack” piece of clickbait on LinkedIn has any validity to it, and what level of expertise the poster actually has when it comes to generative AI.
Someone who says, “this is the ultimate ChatGPT prompt” and then produces a one paragraph prompt is potentially misleading you, now that you’ve seen how the attention mechanism works, and how much information you could have in the context window with the RAPPEL framework. Someone who shows a prompt that doesn’t ask the AI to think out loud, to fill the context window, or to leverage the strengths (and avoid the weaknesses) of generative AI is also potentially misleading you.
And someone asking you to buy a book of prompts for 50 is likely misleading you, because the RAPPEL framework shows you just how custom and detailed a prompt should be to your specific use cases. When you use the RAPPEL framework as we walked through it, you’ll develop your own extensive prompts that are tuned just to your needs – something that no50 collection of generic prompts will ever match.
The true benefit and power of generative AI is to perform tasks at a human level that are unique and custom to you and your needs. Now that you know better how it works, you’ll be able to make it work better for you.

In today’s episode, you’ll discover why spam hasn’t improved despite the advancements in generative AI, and how this relates to legitimate business practices. You’ll learn that the high cost of using advanced AI models like OpenAI’s O1 doesn’t always justify the marginal performance improvement, as seen in the spam industry’s focus on cost-effectiveness. You’ll understand the importance of evaluating whether a task truly requires AI, emphasizing the need to focus on what’s valuable rather than just what’s possible. By applying these insights, you’ll be better equipped to make strategic decisions about AI adoption in your marketing efforts, ensuring you prioritize foundational, proven methods over high-cost, high-consumption AI for the sake of novelty.
Mind Readings: Why Isn't Spam Any Better in the Age of AI?
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, let’s talk about spam. Why isn’t AI spam better? We are living in the age of generative AI when generative AI can do all sorts of crazy things. It can mimic any style. It can write incredibly persuasively. Why isn’t spam getting any better? Why is spam so bad still from LinkedIn comment bots saying, “Hey, Chris, great point on AI.” A little rocket chip emoji. I’m like, oh, I’ve seen. So want to ban you. Here’s why. Spam always comes down to cost. Using foundation models like Gemini or Chat, GPT or Anthropic Claude — these models are highly fluent and highly persuasive, but they are highly expensive. They cost much more money per token than programmatic low-cost garbage. And the goal of spam and spammers, like many legitimate businesses, is maximizing profits. You’re not going to want to spend $100,000 on API calls to reap, a million dollars in profits from scamming people. You want to spend no money, send out garbage, and capture and not spend that million bucks that you earn back.
Here’s the other thing about spam. There’s an element of screening to spam. Spammers have to screen their leads, same as any other form of marketing. When you produce garbage ads, those ads will only recruit a certain kind of person — the exceptionally susceptible person. Everyone else who has even a shred of critical thinking ignores spam. You look at it and go, that’s spam, and you just delete it. You don’t need AI to mimic some foreign prints asking if you have the ability to help him move proceeds from his country’s revolution to a U.S. bank account. You and I know that is spam, that’s garbage. That is a scam, a hundred percent of scam. But we’re not the target audience. We are not the buyers. We are not the people who will get involved in that. And so spammers don’t have to use AI for that. Spammers have been doing this for decades with great success because, as P.T. Barnum was put, there’s a sucker born every minute.
What does this have to do with legitimate businesses? As you think about applying AI to all the tasks you face, especially the marketing ones, one of the things to think about most is whether or not the task that you’re working on even needs AI or not. To quote the fictional Dr. Ian Malcolm from Jurassic Park, “Your scientists were so preoccupied with whether they could that they never stopped to think about whether they should.” Katie shared the other day on LinkedIn that a great theme for 2025 is sticking into your foundations to the fundamentals. I wholeheartedly agree. The technology of generative AI is changing incredibly quickly. Over the holiday season, Deep Seek version 3 shocked the AI world at both its performance and its meager training costs, which dramatically changes the cost equations of generative AI, but those surface details don’t really change how we use AI or whether we should or not. It just changes the implementation. It’s kind of like a better blender coming out. If you don’t need to blend things, if you’re making steak, it doesn’t matter how good the blender is, you’re still making steak. Cooking steak in a blender is a bad idea.
The surface details, the technology changes, the glitz and the glamour, the shock and the dazzle, as Katie would say. All of that doesn’t change the fundamentals of how you should be using AI, why you should be using AI, or why not to. The road ahead for 2025 will expand what’s possible with AI. We’re already seeing this, but we need to focus not only on what’s possible but what’s valuable. Using AI for the sake of AI when there are proven alternatives can be fun but distracting. Using high-cost, high-consumption AI without considering the alternatives can be downright dangerous. If you look at the cost of major models, a model like OpenAI’s O1 is 56 times the cost of deep seek V3 for an 8.1% performance improvement. You spend 56 times more money for an 8% improvement. O1 highlights what’s possible, but deep seek clearly is more valuable for your long-term AI usage.
Spammers figured out a long time ago that focusing on what’s valuable is more important. Scamming the gullible is more important to a spammer than the coolest technology. While I do not advocate that to take up spam as a profession, their focus on the foundation, on what is proven, it’s a great focus to bring it to the new year. Thanks for tuning in.

Mind Readings: Time For the Prompt Regeneration Dance
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
Let’s do the prompt regen again, song to the tune of, let’s do the time work again, but I’m not going to be singing in this episode or ever. In the past few weeks, we have had a tidal wave of new models to work with, new models to experiment with, from OpenAI releasing 01 in production to Google’s Gemini 2.0 Advanced and Gemini 2.0 Flash to Deepseek version 3, to Alibaba’s QWQ. There’s been so many new models, so much change. And if you try these different models out, you have no doubt noticed they behave differently than their predecessors. Under the hood, they’re different creatures. We don’t know exactly what is different, but we know they operate differently because they give different results for the same prompt.
Let me show you an example of this. Let’s see if I can bring my desktop up here. Here’s a very naive prompt. This is what I asked. I said, “I want it to rewrite this.” I said, “Write a 250-word blog post about the importance of email list hygiene for B2B marketers. Be sure to cover things like deliverability, SMTP protocols, SPFD, Kim, DMark, and so on and so forth. Do your best to use knowledge only from 20203, 2024.” That’s pretty reasonable.
Now, let’s look at the different ways those models responded. So, here is the prompt. Gemini 1.5 came back and said, “You’re an expert email marketing, expert writing a blog post for this audience, structure words like this. Here’s the template, focus of providing the actionable insights, write the blog post.” Gemini 2.0 Flash came back and said, “Okay, you’re an experienced B2B marketing consultant, so on, so forth, before you start writing, take a moment and step back to refresh your understanding of why is deliverability important. What are the fundamental issues? Why are the concepts like important?” We see with that foundation, here’s write the post, try to vary the sentence length, use active voice and focus on creating compelling, engaging, informative text. Please evaluate your work based on a checklist. Gemini 2.0 advanced came up with your seasoned B2B email marketing expert, generate a list of key facts and best practices, explain how you use each point. Then using the generated knowledge right in the blog post, here’s the checklist, consider the following. And then Gemini 2.0 Flash thinking, which is their thinking model, came up with this much shorter prompt.
It’s so fascinating. These are all the same family. These are all Google Gemini. But they are, Gemini came up with very different answers. Gemini 1.5 Pro is today’s current state-of-the-art model. That’s in production. 2.0 Flash is Google’s new high-speed model for high-speed, low-latency. 2.0 advanced is their latest version of Gemini. This is the pro version. Flash thinking is their attempt at an 01-like model. And so we see 1.5 tried few-shot and some structured prompting. 2.0 flash does reflection techniques from prompt engineering. Checklist prompting was just type of chain of thought. 2.0 advanced through the kitchen sink, roll prompting, generated knowledge, chain of thought, checklists, reflect the works. It tried everything. And 2.0 flash thinking, actually, for a thinking model, created the least good result.
What’s critical to note here is that each model thinks is the best way to optimize the prompt to get the job done. They’re all different. Even though it’s the same family, all of the ways they tried to optimize that prompt are different. What does this mean? Well, here’s the key takeaway. Every time a model maker releases a new model, you have to go back and take prompts you built for the previous model and retune them for the new model. It’s very clear when you use this example that I use, that 1.5 pro for Gemini and 2.0 advanced, 2.0 wants things done a different way. It wants things to be structured a different way, which means that if you have a bunch of Gemini 1.5 Pro prompts laying around and just copy and paste them as a 2.0, they will underperform. In some cases dramatically. I’ve had this happen with some of my transcript cleanup programs. And this is true for every vendor, Anthropic, OpenAI, Meta, Mistral, Alibaba Cloud, you name it.
It’s kind of like a new model of a car. Yes, it’s still fundamentally the same, but the interface changes from year to year, and those changes add up. The controls in a 2007 Prius are very different from a 2024 Prius. For example, what you need to do, your homework is to build into your planning cycles for AI that whenever a new model comes out, you need to spend some time retuning your prompts, especially if you have them encoded in other software. And especially if you’re working with vendors, if vendors are using these models behind the scenes, they need to present to you their plan of action for how they test and adapt and switch out to new models. Because you don’t want to work with the vendors like, “Oh, we’ve settled on this model and we’re never going to change.” That’s not great because as new models come out, new state-of-the-art capabilities come out, you don’t want to miss out on those. But you also don’t want to be in a situation where you come into work one day and nothing works the way it should because everything behind the scenes, the under the hood has changed.
So, you have to have an agile and rapid change management process so that when a model changes, you know what you have to change on in your infrastructure to make that new model work for you. That’s going to do for today’s episode. Thanks for tuning in. Talk to you next time. If you enjoyed this video, please hit the like button. Subscribe to my channel if you haven’t already.

In today’s episode, you’ll discover the key to boosting productivity without relying on technology, AI, outsourcing, or offshoring. The secret is simple, yet it’s often overlooked by companies. You’ll gain insights into how eliminating unproductive activities can transform your work life and free up 50% of your workload. You’ll benefit from practical advice on focusing your efforts on tasks that truly matter, leading to innovation, creation, and impactful results.
What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.
In today’s episode, let’s review an old management maxim. Do more with less, and its modern contemporary works harder, not harder. This has been management’s mantra since the Reagan administration when corporate profits and workers’ wages diverged and never synced back up. We’ve been on a tear since then, from outsourcing and nearshoring and offshoring to generative AI in ongoing efforts to prop a profitability by spending less money on people in other costs and charging more money.
However, these techniques, yes, they’ve produced increased profitability and increased productivity. But companies tend to ignore one of the most straightforward ways to do this. That requires no technology at all, no AI, no outsourcing, no offshoring, none of that. And the cost savings are considerable. You want to know what it is? Stop doing useless shit. Stop doing irrelevant shit. Stop doing any activity that doesn’t drive an outcome other than cover your own ass.
When I look back at the last 25 years I’ve spent in corporate America, it is fair to say that at most jobs — not my current job, thankfully, because I’m my own company now — but at most of the jobs I’ve had in other people’s companies, more than 50% of my productivity was office politics, reporting for the sake of reporting, making PowerPoints about things, meetings for the sake of meeting, pre-meeting meetings, and have pre-meeting meeting for the meeting. Easily 50% of my time was spent helping my bosses cover their own asses. I saw this firsthand when Katie and I started Trust Insights six years ago, almost seven years ago now. The amount of time I spend on that stuff these days is nearly zero.
We’re a small company. We don’t have committees and task forces and all the corporate jargon that goes with things that are meant to cover your ass or your boss’s ass. Anytime I see the word committee, steering committee, or task force, I’m like, somebody’s feeling a little exposed on the backside. When we started the company, I remembered looking at my calendar going, “What is all this time I have? I have a tremendous amount of time.” We’ve kept that. Everything that we do today has a productive purpose.
Now, yes, there are people, there are clients who still enjoy meetings for the sake of having meetings sometimes, but that’s okay. They pay for the privilege, so we’re still earning money on it. Yes, there are some clients who sometimes just want reporting for reporting’s sake, and it doesn’t mean anything. But they still pay for that, too. What we don’t do is we don’t do that stuff for ourselves. We don’t make stuff just to make stuff for ourselves. Everything has some kind of purpose.
Even things like content and the stuff that we make for our live stream on Thursdays, all of that has a purpose. The live stream that we did on Halloween candy, a lot of that code got reused in a client project for a very, very large company, an enterprise company, is using code that was written originally for detecting Halloween candy names. Now, granted, we have made substantial upgrades and changes. It’s not just a rip and replace, a copy, paste. But even things that we do seemingly for fun still have a purpose.
So, here’s my question challenge to you, particularly as we’re getting started in the new year. What would happen if 50% of your workload, the unproductive half, went away? What would work look like? Retailer John Wanamaker was famously quoted from, I want to say it was 1851, famously quoted and then re-quoted many, many times and misattributed. 50% of his ad spend is a waste, but the problem is he doesn’t know which 50% it is. 50% of your workload is probably a waste, but you know exactly what it is that you do that is not productive.
What would happen if that 50% went away? You wouldn’t have to do more with less. You wouldn’t have to figure out on-shoring and near-shoring and off-shoring and how do we use generative AI to replace more people. You don’t have to do more with less because you just do less of the stuff that doesn’t matter. You spend all your time on the stuff that does matter. Things like innovation and ideation, creation and just shipping things, deliver stuff. Ship, ship, ship, ship.
If your company doesn’t have it to act together, people will use things like AI to do more of what they already do. And while AI absolutely can’t help them do it faster and better, what’s the point of doing useless shit faster and better? You’re just going to make more useless shit. Katie formalized the Trust Insights 5P framework more than a year ago. While AI is cool and amazing, the 5P framework is what unblocks you so that you can unlock value with any technology, including AI. So, if you can start there and stop doing useless shit entirely, you won’t need AI to optimize and speed it up. Instead, you’ll be able to focus on getting things done that you can be proud of that will show lasting impact on your business, your customers, and your career.
Don’t do more with less. Do less of the stuff that doesn’t matter. Thanks for tuning in. Talk to you on the next one. If you enjoyed this video, please hit the like button.
