Yes, and he was way ahead of the curve here, since similar positions got a lot more mainstream in the past years and months. E.g. two of three AI Turing award winners (Hinton and Bengio) now say that superintelligent AI poses a serious extinction risk. OpenAI has also identified the alignment problem as a major issue. Even former AI skeptics like Douglas Hofstadter now broadly agree with this assessment. Yudkowsky's opinion was quite prescient.
This is a bubble conversation that makes no sense to people outside of that bubble, and for good reason; it doesn't matter outside of that bubble.
I know how to find the statements by Hinton and Benigo that superintelligent AI poses a serious extinction risk, but I can't find any statements by Hinton and Benigo--or anyone who is taking the risk seriously--suggesting that air strikes would not be warranted, so any clues on where to look would be appreciated.
Though I'm sure he hopped on the "deepfakes are bad" bandwagon at some point to further his time in the spotlight.
