People should really focus on ideas. He is just a dude, and evidently a cult formed around him. I have stayed away in part from certain movements like effective altruism despite independently coming to the same logical inclusions long before hearing about them, because my suspicion that a lot of those in the movement were pursuing social status. That further seemed to develop into a cult. That's not to say that the effective altruist community is uniquely cult-y, it's probably less so than any other human community, but for a community that also calls itself rationalist you would think they would have disposed of that sort of behaviour long ago.

In short he's just a guy, people should stop focussing so much on people like that, and people should focus on the ideas like the potential impending threats of artificial intelligence, as well as other progress for humanity.
