Scott Aaronson:

I said that my “Faust parameter” — the probability I’d accept of existential catastrophe in exchange for learning the answers to humanity’s greatest questions — might be as high as 0.02.  Though I never actually said as much, some people interpreted this to mean that I estimated the probability of AI causing an existential catastrophe at somewhere around 2%.

[…]

Even before AI, I assigned a way higher than 2% probability to existential catastrophe in the coming century—caused by nuclear war or runaway climate change or collapse of the world’s ecosystems or whatever else.  This probability has certainly not gone down with the rise of AI, and the increased uncertainty and volatility it might cause.  Furthermore, if an existential catastrophe does happen, I expect AI to be causally involved in some way or other, simply because from this decade onward, I expect AI to be woven into everything that happens in human civilization.  But I don’t expect AI to be the only cause worth talking about.

[…]

So, if we ask the directly relevant question — do I expect the generative AI race, which started in earnest around 2016 or 2017 with the founding of OpenAI, to play a central causal role in the extinction of humanity? — I’ll give a probability of around 2% for that. And I’ll give a similar probability, maybe even a higher one, for the generative AI race to play a central causal role in the saving of humanity. All considered, then, I come down in favor right now of proceeding with AI research … with extreme caution, but proceeding.
