There’s an astounding level of arrogance required to believe he is somehow uniquely capable of bringing about a technology especially considering Anthropic came after OpenAI where he worked.
Place yourself at the head of one of like 3 companies the entire rest of the world has been taking about nonstop for 4+ years now. You can move forward or you stop. If you move forward you get to have a hand in how stuff turns out and you make a gajillion dollars. If you stop, it's somebody else's hand in stuff, and you don't get to make a gajillion dollars. And if you shut it all down? Then you just cede to the competition. Everything happens anyway.
What's your play?

I don't think it is particularly egotistical to say that you can be a more ethical CEO than Sam Altman.
