I don't know a lot about Sam Altman's history, but I do know that there is a lot of misattribution in tech circles away from the doers and toward the managers. Has he had significant tangible results, or has he managed people who have had those tangible results?

This sort of misattribution seems to show up when you have individuals with sociopathic tendencies running firms that do cool things: Elon Musk is the king of this. The man has not, on his own, had any sort of good results on the world - Tesla and SpaceX seem to do a lot better when he steps away from them - but he has found ways to get himself into a position to take credit from the engineers who do. Hyperloops and Twitter are the results of Elon Musk's original work. That's not to say that the management is necessarily negative: someone needs to fund the work of the good engineers.
