There's tons of extremely effective marketing around who this guy is, what he stands for - and so I'd instead look at what he's done. He took a non-profit intended to offset the commercial motives driving AI development, and turned it into a for profit closely tied to Microsoft. I think he's an extremely shrewd executive and salesman, but nothing he's done suggests any altruistic motivations - that part always seems…
He didn’t take equity in OpenAi. Does that suggest altruism?
Some people have technology visions which they direct their capital towards. I sense his interest is actually a mix of cultural and social. Is it altruistic? Maybe, but maybe not... It's probably more useful to consider if the vision is or is not restictively utopic and if you think it should or shouldn't be orchestrated / heavily influenced into existence from a central power structure. Is his vision and approach socially aligned?
