It seems clear to me that LLMs are a useful sort of dumb smart activity. They can take some pretty useful stabs in the dark, and therefore do much better in an environment which can give them feedback (coding) or where there is no objective correct answer (write a poem). It opens the door for some novel type of computational tasks, and the more feedback you can provide within the architecture of your application, the more useful the LLM will probably be. I think the hype of their genuine intelligence is overblown, but doesn’t mean they are not useful.

From my perspective, the fundamental problem arises from the assumption that brain's all functions are self contained, however there are feedback loops in the body which supports the functions of the brain. The simplest one is fight/flight/freeze. Brain starts the process by being afraid, and hormones gets released, but next step is triggered by the nerve feedback coming from the body. If you are using beta-blockers…

Sure, your points about the body aren’t wrong, but (as you say) LLMs are only modelling a small subset of a brain’s functions at the moment: applied knowledge, language/communication, and recently interpretation of visual data. There’s no need or opportunity for an LLM (as they currently exist) to do anything further. Further, just because additional inputs exist in the human body (gut-brain axis, for example) it doe…

The point is that knowledge/language work can't work reliably unless it's grounded in something outside of itself. Without it you don't get an oracle, you get a superficially convincing but fundamentally unreliable idiot savant who lacks a stable sense of self, other, or real world.

The fundamental foundation of science and engineering is reliability.

If you start saying reliability doesn't matter, you're not doing science and engineering any more.

If you're right, there will soon be a flood of software teams with no programmers on them - either across all domains, or in some domains where this works well. We shall see. Indeed I have no experience with Claude Code, but I use Claude via chat, and it fails all the time on things not remotely as hard as orientation in a large code base. Claude Code is the same thing with the ability to run tools. Of course tools h…

> Indeed I have no experience with Claude Code, but I use Claude via chat... These are not even remotely similar, despite the name. Things are moving very fast, and the sort of chat-based interface that you describe in your article is already obsolete. Claude is the LLM model. Claude Code is a combination of internal tools for the agent to track its goals, current state, priorities, etc., and a looped mechanism for k…

Claude Code isn't an LLM. It's a hybrid architecture where an LLM provides the interface and some of the reasoning, embedded inside a broader set of more or less deterministic tools.

It's obvious LLMs can't do the job without these external tools, so the claim above - that LLMs can't do this job - is on firm ground.

But it's also obvious these hybrid systems will become more and more complex and capable over time, and there's a possibility they will be able to replace humans at every level of the stack, from junior to CEO.

If that happens, it's inevitable these domain-specific systems will be networked into a kind of interhybrid AGI, where you can ask for specific outputs, and if the domain has been automated you'll be guided to what you want.

It's still a hybrid architecture though. LLMs on their own aren't going to make this work.

It's also short of AGI, never mind ASI, because AGI requires a system that would create high quality domain-specific systems from scratch given a domain to automate.

The post is based on a misconception. If you read the blog post linked at the end of this message, you'll see how a very small GPT-2 alike transformer (Karpathy nano-gpt trained to a very small size) after seeing just PGN games and nothing more develops an 8x8 internal representation with which chess piece is where. This representation can be extracted by linear probing (and can be even altered by using the probe in…

The post or rather the part you refer to is based on a simple experiment which I encourage you to repeat. (It is way likelier to reproduce in the short to medium run than the others.)

From your link: "...The first was gpt-3.5-turbo-instruct's ability to play chess at 1800 Elo"

These things don't play at 1800 ELO, though maybe someone measured this ELO without cheating but rather relying on some artifacts of how an engine told to play at a low rating does against an LLM (engines are weird when you ask them to play badly, as a rule); a good start to a decent measurement would be to try it on chess 960. These things do lose track of the pieces in 10 moves. (As do I absent a board to look at, but I understand enough to say "I can't play blindfold chess, let's set things up so I can look at the current position somehow")

Those spec sheets exist: they're called software.

Not exactly. It depends how software is written and if there is ADRs in the project. I had to work on projects where there was bugs because someone coded business rules in a very bad and unclear way. You move an if somewhere and something breaks somewhere else. You ask « is this condition the way it’s supposed to work or is it a bug » when software is not clear enough - and often it isn’t because we have to go fast -…

Right: software is not necessarily a sufficiently-clear specification, but a sufficiently-clear specification would be software – and you've correctly identified that a good part of your job is ensuring the software provides a sufficiently-clear specification.

Amazingly-written software is necessary for LLMs to work well, but it isn't sufficient: LLMs tend to make nonsensical changes that, while technically implementing what they're asked to do (much of the time), reduce the quality of the software. As this repeats, the LLMs become less and less able to modify the program. This is because they can't program: they can translate, plagiarise, and interpolate, but they're missing several key programming skills, and probably cannot learn them.

With LLMs being unable to count how many Bs are in blueberry, they clearly don't have any world model whatsoever. That addition (something which only takes a few gates in digital logic) happens to be overfit into a few nodes on multi-billion node networks is hardly a surprise to anyone except the most religious of AI believers.

Ask a kid that doesn't know how to read and write how many Bs there are in blueberry.

For a kid that doesn't know to read or write, Chat GPT writes way too much.

I have recently lived through something called a psychotic break, which was an unimaginably horrible thing, but it did let me see from the inside what insanity does to your thinking. And what's fascinating, coming out the other side of this, is how similar LLMs are to someone in psychosis. Someone in psychosis can have all the ability LLMs have to recognise patterns and sound like they know what they're talking about…

If we just take simply a panic attack, many people have no clue what or how it feels like, which is unfortunate, because they lack empathy for those who do experience it. My psychiatrists definitely need to experience it to understand.

Thank you for sharing, and sorry you had to go through that. I had a good friend go through a psychotic break and I spent a long time trying to understand what was going on in his brain. The only solid conclusion I could come to was that I could not relate to what he was going through, but that didn’t change that he was obviously suffering and needed whatever support I could offer. Thanks for giving me a little bit of insight into his brain. Hope you were/are able to find support out there.

Of course they do stuff like that, otherwise it would look like they are stagnating. Fake it till you make it. Tho, at this point, the world is in deep shit, if they don’t make it…

What deep shit do you foresee? My prediction is that this will be like the 2000 dot com bubble. Both dot com and AI are real and really useful technologies but hype and share price has got way ahead of it so will need to re adjust.

A major economic crisis, yes. I think the web is already kinda broken because of AI, gonna get a lot worse. I also question its usefulness… Is it useful solving any real problems, and if so how long before we run out of these problems? Because we conflated a lot of bullshit with innovation right before AI. Right now people may be getting a slight edge, but it’s like getting a dishwasher, once expectations adjusted things will feel like a grind again, and I really don’t think people will like that new reality in regard to experience of self-efficacy (which is important for mental health). I presume the struggle to get information, figuring it out yourself, may be a really important part of putting pressure towards process optimization and for learning, cognitive development. We may collectively regress there. With so many major crisis, a potential economic crisis on top, I am not sure we can afford losing problem solving capabilities to any extent. And I really, really don’t think AI is worth the fantastical energy expenditure, waste of resources and human exploitation, so far.
