Ignoring the recent events, Is Elon Musk actually a genius or does he just hire smart people for him?

Ignoring the recent actions of the guy, is Elon Musk actually smart? People used to (and some still do) think of him as a real-life Tony Stark, but I genuinely cannot think of anything he himself has actually done. If anything, he is just hindering development, like with the cyber truck rectangle steering wheel, or wanting his rocket more pointy. Is the guy actually a genius, or is he just hiring smart people and raking credit?
