I was under the impression he was the money / marketing guy, I didn't realise he built or designed any rockets / EVs himself.
It is clearly non-trivial to rally a group of people, funding sources, and, er, marketing resources to accomplish what he has accomplished.
Evidence: nobody else has done it.
Er... what? He's focussed his attention on some specific problems and made good progress solving them; people have been doing that for as long as there have been people.
Sure he's had great success and clearly does a lot of things well. He's not singular in that.
