The main point is, you need a crazy person to have crazy ideas. Even if 95% of his ideas are shot down, the last 5% are still crazy shit nobody else would thought was possible and never bother to seriously pay some engineers to try it if he wasn't in a leadership position.

Without him, there will be much less crazy, but both the good and bad kind. I fear the day SpaceX just becomes another Boeing.

Seriously, just landing rockets was laughed off as a stupid waste of time by all the industry incumbents just 6 years ago. That was a crazy stupid Elon Musk idea even dumber than the cybertruck at the time, and look where we are now.
