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 certainly don't know him, but I see more reasons not to trust him than to trust him.
What's sketchy about it is that they were offering money to largely poor and technologically naive populations in exchange for gathering very sensitive biometric data from them. Identifying data that cannot be changed and can be used to track them without their knowledge. Their stated goal is to have every person on Earth take part, to boot. The whole idea couldn't set off more alarm bells if it tried.
I give them style points for using truly dystopian-looking "orbs" to do it, though.
