Will you not agree that him becoming "the driving force of OpenAI" involved some highly publicized back-to-back persuasion drama as well? First he got Ilya and gdb to side with him against Elon, then he got OpenAI employees to side with him against Ilya and the board (a board that accused him of deceiving them). PG reiterated after that drama that Altman's special talent was becoming powerful.
This observation does not necessarily mean someone is a bad CEO, since the job of the CEO is to do good by your investors or future investors. And it's possible to do that without any morals whatsoever. But I think the recent drama did more to drive the competition than some of his investors would have liked.
Edit:
>At that time, OpenAI had no clear path to becoming the unicorn it is today, and YC was definitely better from a career standpoint.
This is very incorrect in my view. The presence of Elon Musk as investor and figurehead and Ilya, Karpathy, and Wojciech as domain experts, not to mention investments from YC members themselves (and the PayPal mafia) made OpenAI a very attractive investment early on.
