Humans don't make mistakes nearly as much, the mistakes they do make are way more predictable (they're easier to spot in code review), and they don't tend to make the kinds of catastrophic mistakes that could sink a business. They also tend to cause codebases to rapidly deteriorate, since even very disciplined reviewers can miss the kinds of strange and unpredictable stuff an LLM will do. Redundant code isn't evident in a diff, and things like tautological tests, or useless tests where they're mocking everything and only actually testing the mocks. Or they'll write a bunch of redundant code because they really just aggressively avoid code re-use unless you are very specific.

The real problem is just that they don't have brains, and can't think. They generate text that is optimized to look the most right, but not to be the most right. That means they're deceptive right off the bat. When a human is wrong, it usually looks wrong. When an LLM is wrong, it's generating the most correct looking thing it possibly could while still being wrong, with no consideration for actual correctness. It has no idea what "correctness" even means, or any ideas at all, because it's a computer doing matmul.

They are text summarization/regurgitation, pattern matching machines. They regurgitate summaries of things seen in their training data, and that training data was written by humans who can think. We just let ourselves get duped into believing the machine is the where the thinking is coming from and not the (likely uncompensated) author(s) whose work was regurgitated for you.



> Humans don't make mistakes nearly as much [...]

Yeah, I remember how in every large corporation the specs were perfectly interpreted and with no issues, at all. Humans are great at communication and understanding each other.

I don't really see this argument playing out.

As much as I was trying out copilot — if I ask it to make "todo app" it will make me a "todo app" it will not hallucinate making "calculator app".

Duplicated code or tautological tests are not going to sink the business.

From my experience I have seen much more problems and hours burned caused by wrong application of DRY than from duplication.

I can say that in regulated environments duplicated code that has no abstractions is even preferred.


>The real problem is just that they don't have brains, and can't think.

That would have had more weight if you haven't just described junior developer behavior beforehand.

"LLMs can't think" is anthropocentric cope. It's the old AI effect all over again - people would rather die than admit that there's very little practical difference between their own "thinking" and that of an AI chatbot.


> That would have had more weight if you haven't just described junior developer behavior beforehand.

Effectively telling that junior developers "don't have brains" is in very bad taste and offensively wrong.

> people would rather die than admit that there's very little practical difference between their own "thinking" and that of an AI chatbot.

Would you like to elaborate on this?

I was told that McDonalds employees would have been replaced by now, self-driving cars will be driving the streets and new medicines would have been discovered.

It's been a couple of years that "AI" is out, and no singularity yet.


LLMs use the same type of "abstract thinking" process as humans. Which is why they can struggle with 6-digit multiplication (unlike computer code, very much like humans), but not with parsing out metaphors or describing what love is (unlike computer code, very much like humans). The capability profile of an LLM is amusingly humanlike.

Setting the bar for "AI" at "singularity" is a bit like setting requirements for "fusion" at "creating a star more powerful than the Sun". Very good for dismissing all existing fusion research, but not any good for actually understanding fusion.

If we had two humans, one with IQ 80 and another with IQ 120, we wouldn't say that one of them isn't "thinking". It's just that one of them is much worse at "thinking" than the other. Which is where a lot of LLMs are currently at. They are, for all intents and purposes, thinking. Are they any good at it though? Depends on what you want from them. Sometimes they're good enough, and sometimes they aren't.


> LLMs use the same type of "abstract thinking" process as humans

It's surprising you say that, considering we don't actually understand the mechanisms behind how humans think.

We do know that human brains are so good at patterns, they'll even see patterns and such that aren't actually there.

LLMs are a pile of statistics that can mimic human speech patterns if you don't tax them too hard. Anyone who thinks otherwise is just Clever Hans-ing themselves.


We understand the outcomes well enough. LLMs converge onto a similar process by being trained on human-made text. Is LLM reasoning a 1:1 replica of what the human brain does? No, but it does something very similar in function.

I see no reason to think that humans are anything more than "a pile of statistics that can mimic human speech patterns if you don't tax them too hard". Humans can get offended when you point it out though. It's too dismissive of their unique human gift of intelligence that a chatbot clearly doesn't have.


> We understand the outcomes well enough

We do not, in fact, "understand the outcomes well enough" lol.

I don't really care if you want to have an AI waifu or whatever. I'm pointing out that you're vastly underestimating the complexity behind human brains and cognition.

And that complex human brain of yours is attributing behaviors to a statistical model that the model does not, in fact, possess.


[flagged]


I think saying that "LLMs can produce outcomes akin to those produced by human intelligence (in many but not all cases)" and "LLMs are intelligent" to both be fairly defensible.

> I see no reason whatsoever to believe that what your wet meat brain is doing now is any different from what an LLM does.

I don't think this follows though. Birds and planes can both fly, but a bird and a plane are clearly not doing the same thing to achieve flight. Interestingly, both birds and planes excel at different aspects of flight. It seems at least plausible (imo likely) that there are meaningful differences in how intelligence is implemented in LLMs and humans, and that that might manifest as some aspects of intelligence being accessible to LLMs but not humans and vice versa.


> It seems at least plausible (imo likely) that there are meaningful differences in how intelligence is implemented in LLMs and humans

Intelligence isn’t "implemented" in an LLM at all. The model doesn’t carry a reasoning engine or a mental model of the world. It generates tokens by mathematically matching patterns: each new token is chosen to best fit the statistical patterns it learned from its training data and the immediate context you give it. In effect, it’s producing a compressed, context-aware summary of the most relevant pieces of its training data, one token at a time.

The training data is where the intelligence happened, and that's because it was generated by human brains.


There doesn't seem to be much consensus on defining what intelligence is. For the definitions of at least some reasonable people of sound mind, I think it is defensible to call them intelligent, even if I don't necessarily agree. I sometimes call them "intelligent" because many of the things they do seem to me like they should require intelligence.

That said, to whatever extent they're intelligent or not, by almost any definition of intelligence, I don't think they're achieving it through the same mechanism that humans do. That is my main argument. I thing confident arguments that "LLMs think just like humans" are very bad, given that we clearly don't understand how humans achieve intelligence and the vastly different substrates and constraints that humans and LLMs are working with.


I guess to me, how is the ability to represent the statistical distribution of outcomes of almost any combination of scenarios, represented as textual data not a form of world model?


I think you're looking at it too abstractly. An LLM isn't representing anything, it has a bag of numbers that some other algorithm produced for it. When you give it some numbers, it takes them and does matrix operations with them in order to randomly select a token from a softmax distribution, one at a time, until the EOS token is generated.

If they don't have any training data that covers a particular concept, they can't map it onto a world model and make predictions about that concept based on an understanding of the world and how it works. [This video](https://www.youtube.com/watch?v=160F8F8mXlo) illustrates it pretty well. These things may or may not end up being fixed in the models, but that's only because they've been further trained with the specific examples. Brains have world models. Cats see a cup of water, and they know exactly what will happen when you tip it over (and you can bet they're gonna do it).


That video is a poor and mis-understood analysis of an old version of ChatGPT.

Analyzing an image generation failure modes from the dall-e family of models isn't really helpful in understanding if the invoking LLM has a robust world model or not.


The point of me sharing the video was to use the full glass of wine as an example for how generative AI models doing inference lack a true world model. The example was just as relevant now as it was then, and it applies to inference being done by LMs and SD models in the same way. Nothing has fundamentally changed in how these models work. Getting better at edge cases doesn't give them a world model.


That's the point though. Look at any end-to-end image model. Currently I think nano banana (Gemini 2.5 Flash) is probably the best in prod. (Looks like ChatGPT has regressed the image pipeline right now with GPT-5, but not sure)

SD models have a much higher propensity to fixate on proximal in distribution solutions because of the way they de-noise.

For example.. you can ask nano banana for a "Completely full wine glass in zero g" which I'm pretty sure is way more out of distribution, the model does a reasonable job at approximating what they might look like.


That's a fairly bad example. They don't have any trouble taking unrelated things and sticking them together. A world model isn't required for you to take two unrelated things and stick them together. If I ask it to put a frog on the moon, it can know what frogs look like and what the the moon looks like, and put the frog on the moon.

But what it won't be able to do, which does require a world model, is put a frog on the moon, and be able to imagine what that frog's body would look like on the moon in the vacuum of space as it dies a horrible death.


Your example is a good one. The frog won't work because ethically the model won't want to show a dead frog very easily, BUT if you ask nano-banana for:

"Create an image of what a watermelon would look like after being teleported to the surface of the moon for 30 seconds."

You'll see a burst frozen melon usually.


> "We don't fully understand how a bird works, and thus: "wind tunnel" is useless, Wright brothers are utter fools, what their crude mechanical contraptions are doing isn't actually flight, and heavier than air flight is obviously unattainable."

Completely false equivalency. We did in fact back then completely understand "how a bird works", how the physics of flight work. The problem getting man-made flying vehicles off the ground was mostly about not having good enough materials to build one (plus some economics-related issues).

Whereas in case of AI, we are very far from even slightly understanding how our brains work, how the actual thinking happens.


One of the Wright brothers achievements was to realize the published tables of flight physics was wrong and to carefully redo it with their own wind tunnel until they had a correct model from which to design a flying vehicle https://humansofdata.atlan.com/2019/07/historical-humans-of-...


Ok, that's pretty cool. I didn't know that, thanks!


We have a good definition of flight, we don't have a good definition of intelligence.


"Anthropocentric cope >:(" is one of the funniest things I've read this week, so genuinely thank you for that.

"LLMs think like people do" is the equivalent of flat earth theory or UFO bros.

Flerfers run on ignorance, misunderstanding and oppositional defiant disorder. You can easily prove the earth is round in quite a lot of ways (the Greeks did it) but the flerfers either don't know them or refuse to apply them.

There are quite a lot of reasons to believe brains work differently than LLMs (and ways to prove it) you just don't know them or refuse to believe them.

It's neat tech, and I use them. They're just wayyyyyyyy overhyped and we don't need to anthropomorphize them lol


This is wrong on so many levels. I feel like this is what I would have said if I never took a neuroscience class, or actually used an LLM for any real work beyond just poking around ChatGPT from time to time between TED talks.


There is no actual object-level argument in your reply, making it pretty useless. I’m left trying to infer what you might be talking about, and frankly it’s not obvious to me.

For example, what relevance is neuroscience here? Artificial neural nets and real brains are entirely different substrates. The “neural net” part is a misnomer. We shouldn’t expect them to work the same way.

What’s relevant is the psychology literature. Do artificial minds behave like real minds? In many ways they do — LLMs exhibit the same sorts fallacies and biases as human minds. Not exactly 1:1, but surprisingly close.


I didn't say brains and ANNs are the same, in fact I am making quite the opposite argument here.

LLMs exhibit these biases and fallacies because they regurgitate the biases and fallacies that were written by the humans that produced their training data.


Maybe. That’s not an obvious conclusion in the strong sense that you mean it here. If you train a LLM on transcripts of multiplying very large numbers, machine generated and perfectly accurate transcripts, the LLM still exhibits the same sorts of mental math errors that people make.

Math, logical reasoning, etc. are cultural knowledge, not architecturally built-in. These biases and fallacies arise because of how we process higher order concepts via language-like mechanisms. It should not be surprising that LLMs, which mimic human-like natural language abilities (at the culture/learned level of abstraction, if not computation substrate) exhibit the same sorts of errors.


Living in Silicon Valley, there are MANY self driving cars driving around right now. At the stop light the other day, I was between 3 of them without any humans in them.

It is so weird when people pull self driving cars out as some kind of counter example. Just because something doesn't happen on the most optimistic time scale, doesn't mean it isn't happening. They just happen slowly and then all at once.


15 years ago they said truck drivers would be obsolete in 1-2 years. They are still not obsolete, and they aren't on track to be any time soon, either.
