Is this a reasonable chance to take?
"We don't have any evidence that intelligence equals compute" is worse than "we're 96% confident it doesn't". Ilya Sutskever clearly believes this is a real risk (otherwise he wouldn't have thrown his reputation and wealth to the wind by firing his cofounder yesterday). He is one of the foremost experts. So are two of the "fathers of AI", Hinton and Bengio, who both have no interest in creating a moat and yet signed letters saying "this is an extinction risk, lets treat it like nuclear", one of them quitting his job to be able to say it.
We don't have much evidence for or against, but that's not a great argument against "if it's true, we all die".
