Of course he's a doomer. He's compared himself to Robert Oppenheimer and by his own admission the only reason he isn't calling for a complete halt to all AI research is because he's too pessimistic it'd be possible. He describes a man who wants to literally bomb datacenters as "not crazy", just "not helpful" i.e. he'd be totally on board with such tactics if he thought they were more plausible.

> Talking about the dangers of AI is not the same as being a doomer

It is in fact the same thing as being a doomer, in the same way that pointing out government coverups of lab leaks technically makes you a conspiracy theorist.
