Goodhart's law:
When a measure becomes a target, it ceases to be a good measure.
The Turing Test (as some people believe it to be): if you can have a conversation with a computer and not tell if it's a computer, then it must be intelligent.
AI companies: writes ML model that is specifically designed to convincingly play one side of a conversation, even though it has no ability to understand the things it talks about.
It's worth emphasizing that the "Turing Test" is not a good test since it's not at all scientific.
It's just another thought experiment that grifters have taken to the bank.
Also as Turing proposed it it's meant to be infinitely repeatable. The test isn't supposed to just be if a machine can convince one person with one conversation. That would be trivial. The real Turing test is the converse, it says that there should be no conversation one could have with the machine where it wouldn't convince you it's a human.
The most advanced models absolutely have modeling about what's being discussed and relationships between concepts.
Even toy models have been shown to build world models from very basic training data.
Honestly, read at least a little bit of the relevant research:
There's a reason why the open llm leaderboard was changed a while ago.
Basically, scores didn't improve much anymore and many tests were contained in the training data.
See this blogpost for more info.
"close to meaningless" sums up my expert opinion on the whole current AI hype machine sales pitch.
Highly tuned models for incredibly specific, not-dangerous use cases is the next pragmatic step. There's a lot to excited about, in that very narrow band.
Anyone selling more than that is part of a con, or in very rare cases, doing genuine "fuck off and ask me again in a decade" kinds of research.
Much like IQ tests for humans are flawed too. Figuring out series of numbers or relations in a graphic representation, only tells how good you are at these specific tasks, and doesn't provide a reliable picture of "general" intelligence.
The article makes the valid argument that LLMs simply predict next letters based on training and query.
But is that actually true of latest models from OpenAI, Claude etc?
And even if it is true, what solid proof do we have that humans aren’t doing the same? I’ve met endless people who could waffle for hours without seeming to do any reasoning.
Information theory, entropy in Markovian processes. Read up on these buzzwords to see why.
I think I know enough about these concepts to know that there isn’t any conclusive proof, observed in output or system state, to establish consensus that human speech output is generated differently to how LLMs generate output. If you have links to any papers that claim otherwise, I’ll be happy to read them.
What? Humans, ahem, collect entropy every moment of their existence.
I mean I have an opinion too; what I’m seeking is evidence.
Evidence for what?
I've just diagonally read a google link where the described way humans work with language appears for me to be very similar to GPT in rough strokes. Only human brain does a lot more than language. Hence the comparisons to the mechanical Turk.
Also Russell's teapot.
I’m not saying humans and LLMs generate language the same way.
I’m not saying humans and LLMs don’t generate language the same way.
I’m saying I don’t know and I haven’t seen clear data/evidence/papers/science to lean one way or the other.
A lot of people seem to believe humans and LLMs don’t generate language the same way. I’m challenging that belief in the absence of data/evidence/papers/science.
Like going out and meeting a dino - 50% yes, 50% no. It's a joke.
Russell's teapot again.
what solid proof do we have that humans aren’t doing the same?
Humans are not computers. Brains are not LLMs...
Given a totally reasonable hypothesis (humans =/= computers) and a completely outlandish hypothesis (humans = computers), I would need much more 'proof' for the later.
Well, brains are a network of neurons (we can evidentially verify this) trained on … eyes, ears, sense of touch, taste, smell and balance (rewarded by endorphins released by the old brain on certain hardcoded stimuli). LLMs are a network of neurons trained on text and images (rewarded by producing text that mimics input text and some reasoning tests).
It’s not given that this results in the same way of dealing with language, given the wider set of input data for a human, but it’s not given that it doesn’t either.
Humans predict things by assigning meaning to events and things, because in nature, we're constantly trying to guess what other creatures are planning. An LLM does not hypothesize what your plans are when you communicate to it, it's just trying to predict the next set of tokens with the greatest reward value. Even if you were to use literal human neurons to build your LLM, you would still have a stochastic parrot.
I mean I have an opinion too; what I’m seeking is evidence.
Why should I need to prove a negative? The burden is on the ones claiming an LLM is sentient. LLMs are token predictors, do I need to present evidence of this?
I’m not asking you to prove anything. I’m saying I haven’t seen evidence either way so for me, it’s too early to draw conclusions.
