If an AI or AGI can look at a picture and see an apple, or (say) with an artificial nose smell an apple, or likewise feel or taste or hear* an apple, and at the same identify that it is an apple and maybe even suggest baking an apple pie, then what else is there to be comprehended?
Maybe humans are just the same - far far ahead of the state of the tech, but still just the same really.
*when someone bites into it :-)
For me, what AI is missing is genuine out-of-the-box revolutionary thinking. They're trained on existing material, so perhaps it's fundamentally impossible for AIs to think up a breakthrough in any field - barring circumstances where all the component parts of a breakthrough already exist and the AI is the first to connect the dots ("standing on the shoulders of giants" etc).
It will confidently analyze and describe a chess position using advanced sounding book techniques, but its all fundamentally flawed, often missing things that are extremely obvious (like, an undefended queen free to take) while trying to sound like its a seasoned expert - that is if it doesn't completely hallucinate moves that are not allowed by the rules of the game.
This is how it works in other fields I am able to analyse. It's very good at sounding like it knows what its doing, speaking at the level of a masters level student or higher, but its actual appraisal of problems is often wrong in a way very different to how humans make mistakes. Another great example is getting it to solve cryptic crosswords from back in the day. It often knows the answer already in its training set, but it hasn't seen anyone write out the reasoning for the answer, so if you ask it to explain, it makes nonsensical leaps (claiming birch rhymes with tyre level nonsense)
I know that sounds broad or obvious, but people seem to easily and unknowingly wander into "Human intelligence is magically transcendent".
Hanging a queen is not evidence of a lack of intelligence - even the very best human grandmasters will occasionally do that. But in pretty much every single video, the LLM loses the plot entirely after barely a couple dozen moves and starts to resurrect already-captured pieces, move pieces to squares they can't get to, etc - all while keeping the same confident "expert" tone.
At that point, the question of whether the model really does understand is pointless. We might as well argue about whether humans understand.
I don't know if you're making it, but the simplest mistake would be to think that you can prove that a computer can evaluate any mathematical function. If that were the case then "it's got to be doable with algorithms" would have a fairly strong basis. Anything the mind does that an algorithm can't would have to be so "magically transcendent" that it's beyond the scope of the mathematical concept of "function". However, this isn't the case. There are many mathematical functions that are proven to be impossible for any algorithm to implement. Look up uncomputable functions you're unfamiliar with this.
The second mistake would be to think that we have some proof that all physically realisable functions are computable by an algorithm. That's the Physical Church-Turing Thesis mentioned above, and as the name indicates it's a thesis, not a theorem. It is a statement about physical reality, so it could only ever be empirically supported, not some absolute mathematical truth.
It's a fascinating rabbit hole if you're interested - what we actually do and do not know for sure about the generality of algorithms.
What I’m hearing here is that you are willing to get your surgery done by him and not by one of the real doctors - if he is capable of pronouncing enough doctor-sounding phrases.
But the poster you responded to didn't say it's magically transcendent, they just pointed out that there are many significantly hard problems that we don't solutions for yet.
This is just a thing to say that has no substantial meaning.
- What is "sufficiently" mean?
- What is functionally equivalent?
- and what is even understanding?
All just vague hand wavingWe're not philosophizing here, we're talking about practical results and clearly, in the current context, it does not deliver in that area.
> At that point, the question of whether the model really does understand is pointless.
You're right it is pointless, because you are suggesting something that doesnt exist. And the current models cannot understand
I was almost going to explicitly mention your point but deleted it because I thought people would be able to understand.
This is not a philosophy/theology sitting around handwringing about "oh but would a sufficiently powerful LLM be able to dance on the head of a pin". We're talking about a thing, that actually exists, that you can actually test. In a whole lot of real-world scenarios that you try to throw at it, it fails in strange and unpredictable ways. Ways that it will swear up and down it did not do. It will lie to your face. It's convincing. But then it will lose in chess, it will fuck up running a vending machine buisness, it will get lost coding and reinvent the same functions over and over, it will make completely nonsensical answers to crossword puzzles.
This is not an intelligence that is unlimited, it is a deeply flawed two year old that just so happens to have read the entire output of human writing. It's a fundamentally different mind to ours, and makes different mistakes. It sounds convincing and yet fails, constantly. It will tell you a four step explanation of how its going to do something, then fail to execute four simple steps.
Not sure we need it. The counter example is the LLM itself. We had absolutely zero idea that the attention heads would bring such benefits down the road.
Except it clearly does, in a lot of areas. You can't take a 'practical results trump all' stance and come out of it saying LLMs understand nothing. They understand a lot of things just fine.
From a purely practical standpoint, we don't know of any non-computable physical systems and it's just so painfully god-of-the-gaps to say "The brain could contain new physics that transcends everything we know even though this has never proved true with any other complex system we ever gained knowledge about. It's all proved computable".
