In today’s episode, we’re diving deeper into the world of AGI, but instead of just theory, you’ll discover the five distinct levels of AI development that are the stepping stones to achieving true artificial general intelligence. You’ll learn where we are on that path today and what technological advancements are necessary to climb higher. You’ll gain a realistic perspective on the timeline for achieving AGI and what to expect along the way. Tune in to discover how close we really are to a future with AGI!

Christopher Penn: In this part, part two of our series on artificial general intelligence, we’re going to talk about the path to artificial general intelligence (or AGI), where things are, and where we could be going.
Now, to recap real quick, artificial general intelligence means machines that can do any general task without being specifically built for it. ChatGPT, for example, is a tool that does language, and to some degree now does things like images and stuff. You have these multimodal models like Gemini and things that can do images and process video and audio, but they’re not going to fix a leaky toilet for you.
General intelligence is being able to tackle any problem you throw at it in the same way that you humans do—you and I do.
Let’s talk about the five layers of how you get to artificial general intelligence.
The first layer—well, layer zero—would be no AI, just computers, spreadsheets, where we’ve been for the last 50 years.
Level one is AI that has a very narrow focus: specific single-purpose tools. The AI that has been in place in your inbox for the last 25 years, helping you decide spam or not spam—that’s an example of very narrow AI. It’s good at one thing, and it can’t do anything else. That’s your first rung on the ladder towards artificial general intelligence: single-purpose AI.
The second level is general within a specific domain. We’re talking about ChatGPT: you can ask it to write a poem, you can ask it to write a term paper, you can ask it to write an academic study. We’re still talking about generation—generative—but we’re talking about things where you don’t have to necessarily pre-train it just to do the specific task you want to do. If you want to rephrase a memo, you don’t have to spend an hour, an hour and a half, giving examples of memos and how to rewrite them properly. It’s baked into the model’s knowledge. This AI is sort of a consultant. It is sort of level two on the ladder toward general intelligence.
Level three is things like machines as collaborators, where they can do some of the tasks that you give them, potentially somewhat autonomously. This would be an example where you have an AI agent in your Slack or your Discord for your company, and it’s just doing stuff for you. It attends a meeting, it takes notes, it sends you the notes, it puts things on your calendar. These are not intellectually rigorous tasks, but they are collaborative. They are assistants. You go from a passive consultant that’s just sitting there, waiting to do something, waiting for you to prompt it, to an assistant that can take action and do stuff.
Level four is when you start getting into AI expertise, where you start to get to human and beyond human levels of intelligence. An example of this would be where you have, for example, you go to the doctor, and the machine ingests your medical records and your scans and stuff, and it provides you with that first-level diagnosis, like, “Hey, it looks like your cholesterol is a little high, buddy. You should lay off the quarter pounders.” Then the human essentially confirms that, says, “Yep, that’s, that’s a sensible conclusion.”
The AI is acting as an expert, semi-autonomously. It’s in place to take in a bunch of very generalized situations, like, “Hey, you’ve got this, you’ve got some high cholesterol, and a genetic history of this and things.” It’s at the point where it’s going to perform better than the human to a degree.
We’re at that point today to a degree, for stuff that requires minimal competency. Summarizing meeting notes: If you were to look at the spectrum of executive assistants and administrative assistants, from day one to 30-year veteran, somewhere in the middle, people have been in the profession, five years, 10 years, whatever—they’re good at what they do.
Machines today are at that point where they can do the work as well as an average person. They can’t do the work as well as that 30-year expert who just anticipates and knows, “This is exactly what’s needed at this moment.” They’ve got the life experience; they can do the job way better than that person who just graduated college. They’ve got the English degree, and they’re like, “I don’t even know how to operate this phone system.”
That’s where tools today, like some of the transcription software, can do these summarizations. But when you get to that level for that expertise, you’re talking about things that are beyond human capabilities today, because machines can just hold more in their memories than we can.
If you think about Google’s Gemini, the current Gemini 1.5 model (as of the date of this recording) has a 2 million token context window. Put in practical terms, it can hold two of these in one prompt. You and I can’t do this. We cannot recite, word for word, the entirety of William Shakespeare, accurately, in seconds. Just can’t do it. But machines can hold this much information.
Again, this scale of this ladder towards artificial general intelligence is how things are likely to play out. Autonomous, artificial, super intelligence—machines that are self-directed, machines that understand the world, machines that could be fully autonomous; you say, “Hey, here is this computer network. Optimize it. Optimize for maximum performance.” It decides what maximum performance means. It looks at all the data and starts making changes on its own.
We’re not there yet. We are not there yet, and we will not be there for quite some time because just the compute power alone would be insurmountable as an issue to deal with.
Now, how do we get there? What are the technologies? A lot of the tooling we need exists. We don’t have the compute power. We have deep learning and reinforcement learning with human feedback, and symbolic artificial intelligence. We have all these fancy technologies that essentially allow a machine to learn. You give it an example; it learns from the example, it can do a lot of AI. It’s all machine learning—hence the name “machine learning”—but we’re running into scale issues.
The amount of power that AI consumes is an issue; the amount of memory that a video card can hold to do inference is an issue, and so it’s going to be very challenging to overcome those issues. But if we can, with the variety of technologies that are available, we will be able to make our way up the ladder.
So we are at level—we’re at level two today. Level zero is no AI, level one is narrow purpose tools, level two is broader tools within a domain—ChatGPT, Anthropic, Claude, etc. We are not at level three yet, those collaborators, those semi-autonomous agents. We’re not there yet; we’re getting there. Level three is probably achievable in the next year or two as models get more sophisticated.
Level four, AI superhuman experts—we’re not there yet. It’s going to be a long time, years if not decades. Level five, decades, probably, for a truly autonomous, self-directed machine. We’re a long way away from them.
So in part three, we’re going to talk about what we can expect as we start moving up this ladder as we start getting towards collaborative AI and then expert AI. Stick around for that; we’ll see you on the next one.
