But more to the point, I kind of hate it when someone posts something with an obvious negative/snarky context and then defenders try to pretend "he was just asking a valid question!" In my opinion this would be a much better, and more valid post, if the title were simply "What qualifications led Sam Altman to be CEO of OpenAI" or some such.
And, by the way, your assumptions are wrong, pg has written posts on why he thinks sama is one of the most impressive people he's ever met - they even changed the YC rules after him to make the percentage stake that YC takes standardized and non-negotiable because sama was such a good negotiator.
