From a “lunch with” profile of Sam Altman in the Financial Times:

I find Altman brimming with confidence as our conversation ranges from AI products to the existential question of an AI future that a handful of optimistic technologists are steadily leading us to, whether we like it or not. Radiating ambition, he sounds like a man convinced of his own destiny.

Perhaps you have to be a little overconfident to attempt this. Meanwhile most people are upset that Sam uses the wrong kind of expensive olive oil.
