I find this very surprising. How do people conclude that OpenAI's success is due to its business leadership from Sam Altman, and not from it's technological leadership and expertise driven by Illya and the others?

Their asset isn't some kind of masterful operations management and reign in cost and management structure as far as I see. But about the fact they simply put, have the leading models.

So I'm very confused why would people want to following the CEO? And not be more attached to the technical leadership? Even from investor point of view?
