It isn't like he is the one who did the research to lead to that decision though. That just isn't his job. He isn't an analyst. He is CEO, who reads reports or sat in presentations made by his analysts, whatever their specific position titles, who are really the ones who did the work weighing and making this decision. His role was to say yes to these people whose job it is to actually figure this out.

So indeed, if he was not CEO, likely whoever would have been would be given the same information as Jensen that lead to him saying yes on tensor cores. And in all likelihood, the same exact decision would have been made, or at least a coinflips odds chance if it really were a matter of "yes" or "no" with no clear winner.

I feel like it's worth repeating that he gets credit for the decisions he has made, while it's also true that someone else would also see this demand, maybe earlier maybe later, and that the economy and shareholders would benefit. The point I'm making, and I think the one you're responding to, is that he didnt do something so magical that wouldn't have been done otherwise. It's a counterpoint to "this guy did so much, we would be nothing without him" and using that as a way to excuse his bad decisions.

Again, credit for putting yourself in the position to capitalize. Credit for executing. But it's pretty likely that the world would not be substantially different if Nvidia has been another company and Jensen was some guy working at MS.
