It's surprising that Exponential Time Hypothesis would be false. Quoting a paper from 2022[1]:
> We prove that the time complexity of self-attention is necessarily quadratic in the input length, unless the Strong Exponential Time Hypothesis (SETH) is false[...]
If OpenAI's proof is correct, does that mean self-attention can be implemented in sub-quadratic time? I.e. we could eventually have all the most advanced LLMs running on cheap hardware? To put it more playfully, is ETH being false actually bearish for Nvidia?
No, SETH implies quadratic time does not mean !SETH implies !quadratic time.
but you're telling me.... there's a chance
This but unironically.
put a number on your probabilities. there's a chance you have an aneurysm in the next few minutes and fail to see my comment. if so, oh well, i tried.
If AI really scales indefinitely is an increase in efficiency even bearish for Nvidia? Wouldn't they still build more and more compute as fast as they can, because these things get smarter and better with more compute?
SETH is a much stronger claim than ETH
Not relevant, because !ETH => !SETH
What is relevant is that the logic goes the other way: SETH implies quadratic, !SETH implies nothing.
Right, so a refutation of ETH would also refute SETH.
Yes, it's one strong stronger.
It's playful!
But it's also not even wrong, in the Pauli sense.
That makes me wonder if "I see your CS proof, how does this affect LLMs / nvidia stonk price???" being immediately self-described as "playful" ensures criticism looks cranky.
"I see your particle physics paper (on sustainability of neutron-induced chain fission reaction in uranium), how does this affect the world politics???"
Turns out, it affected the global politics tremendously.
