Eh... Do I think Bezos is a visionary responsible for all of Amazon's success? No. But culture comes from the top. There's a lot of ways to run a company poorly, especially if it's doing something novel and not just churning out mundane products. The big ones involve bureaucracy and short term profits. If Jeff Bezos died, I'm sure Amazon would be just fine. Tesla maybe not. How mature is Alibaba and Ant?

Seems to me that China also has this theory at the moment, with Xi.

Sure, money can't do the impossible, but if you only need a few percentage points it's pretty likely to help

Or did you forget where Apple was when Gil Amelio got ousted for Steve to come back?

As for Apple, putting the questionable meaning of the stock market to one side for a moment, when was the last time they did anything truly exciting, that cut their competitors legs out from under them? The M1 chip? That's the only thing I can think of for a long time, and it's a bit unclear how much consumers will care vs geeks.
