> simulate human-like thought processes

It ought to be clear to a cognitive scientist (which the author is) that we do not know how human thought processes work except at a very course level.

The idea that we have an understanding refined enough to take the next step and "simulate" these processes is just pure crackpot bunk.

“Implementing this in a machine will enable artificial general intelligence” If that’s true why didn’t he just implement it? Why should I take anyone seriously that just talks about code instead of actually coding it? This would be much more compelling if he just showed benchmarks and performance instead of writing up an argument. Furthermore, I don’t believe him.

I looked it up, the author has PhD in Brain and Cognitive Science. Are you aware of the fact that even partially implementing something like this, would require multi-year effort with dozens of engineers at minimum and will cost millions of dollars just for training.

"even partially implementing something like this, would require multi-year effort with dozens of engineers at minimum and will cost millions of dollars just for training"

Unfortunately, that means that's also the bar for being able to utter the words "IMPLEMENTING THIS IN A MACHINE WILL ENABLE ARTIFICIAL GENERAL INTELLIGENCE" and being taken seriously. In fact the bar is even higher than that, since merely meeting the criteria you lay out is still no guarantee of success, it is merely an absolute minimum.

The fact that that is a high bar means simply that; it's a high bar. It's not a bar we lower just because it's really hard.

That's a tiny team, a short timescale, and a trivial cost. Seriously, when you're a bit older you'll see more wasted on the most useless ideas.

Yeah, I think a problem continues to be that there are a bunch of interesting threads in cognitive science research that have seemed sort of decent as explanations of how animal cognition is working, and maybe directionally reasonable (but incomplete) in suggesting how one might implement it in the abstract, but that doesn't suffice to actually build a mind. If there are a bunch of good hypotheses, you need actual results to show that yours is special. I haven't read this thoroughly, but the author cites and reuses a lot of stuff from the 1970s and 1980s ... but so far as I can tell doesn't really answer why these models didn't pan out to actually build something decades ago.

Today, I think active inference and free energy principle (from Friston) are perhaps having a bit more impact (at least showing up in some RL innovations), but are still a long way off from creating something that thinks like we do.

I also think so, in the context of "at minimum".

The perfect way to never have your theories invalidated

I think this is a wrong way to look at the Academia, theoretical groundwork is essential for building practical things.

I like the process that goes into these "imagine the architecture of AGI" articles. It's all hypothetical, but it's really fun.

But it's a missed opportunity if you don't embed LLMs in some of the core modules -- and highlight where they excel. LLMs aren't identical to any part of the human brain, but they do a remarkable job of emulating elements of human cognition: language, obviously, but also many types of reasoning and idea exploration.

Where LLMs fail is in lookup, memory, and learning. But we've all seen how easy it is to extend them with RAG architectures.

My personal, non-scientific prediction for the basic modules of AGI are:

- LLMs to do basic reasoning

- a scheduling system that runs planning and execution tasks

- sensory events that can kick off reasoning, but with clever filters and shortcuts

- short term memory to augment and improve reasoning

- tools (calculators etc.) for common tasks

- a flexible and well _designed_ memory system -- much iteration required to get this right, and i don't see a lot of work being done on it, which is interesting

- finally, a truly general intelligence would have the capability to mutate many of the above elements based on learning (LLM weights, scheduling parameters, sensory filters, and memory configurations). But not everything needs to be mutable. many elements of human cognition are probably immutable as well.

I'm the best musician on earth but I can't play any instruments but I can imagine a really amazing song, you'll just never hear it because it would take 1000s of hours of me practicing to actually learn to play so that I could prove it. So you'll just have to make do with my words and believe me when I say I'm the best musician alive.

Here's an article I wrote describing the song but without actually writing any of the notes because I can't read or write music either.

But I've listened to a lot of music and my tunes are better than those.

I went to school for music description so I know what I'm talking about.

> As a formal algorithm, it could be modeled as a stateless Markov process in discrete time, performing non-deterministic search. As a computable function, it could be instantiated by traditional or neuromorphic computer clusters and executed using brain emulation, hierarchical hidden Markov models, stochastic grammars, probabilistic programming languages, neural networks, or others.

These sentences from section 5.2 convince me that the author is oddly not even interested in building what he's talking about, or making a plan to do so.

- Isn't the point of a markov process that it _is_ stateful, but that _all_ its state is present at in each x_i, such that for later times k > i, x_k never needs to refer to some prior x_j with j - "Here's a list of broad, flexible families of computational processing that can have some concept of a sequence. Your turn, engineers!"
