To set the record straight: I once gave a ~2% probability for the classic AGI-doom paperclip-maximizer-like scenario. I have a much higher probability for an existential catastrophe in which AI is causally involved in one way or another — there are many possible existential catastrophes (nuclear war, pandemics, runaway climate change…), and many bad people who would cause or fail to prevent them, and I expect AI will soon be involved in just about everything people do! But making a firm prediction would require hashing out what it means for AI to play a "critical causal role" in the catastrophe — for example, did Facebook play a "critical causal role" in Trump's victory in 2016? I'd say it's still not obvious, but in any case, Facebook was far from the only factor.
