He's not perfect, but behind the scenes he's a genuine and upstanding person. I've met lots of wealthy smart people, and he's the only exception. He was the only person I trusted in this situation, and I'm genuinely nervous that he's no longer running OpenAI.
I've never met the man, but I can say I have not been impressed by his words and attitude in public. I never got the sense or feeling that he's actually doing right by the world.
Ultimately it doesn't matter if he's a good or bad person; what matters is what he's done.
