I think this article kind of misses a crucial point. They weren't always AI doomers, that's a thing they picked up along the way. Their core beliefs are 1. That they are the smartest, and 2. That this makes them morally superior because consequentialism (This sort of follows. If you believe in consequentialism, leaving all your decisions to the superior consequence predictor is surely the moral thing to do)
Maybe one day they will stop believing in AI doom, but they will never, ever stop believing they belong to the intellectually and thus morally elect. The day any of them do that they have either broken with the cult or died.
