> How much hands-on tech involvement does Musk actually have in his enterprises?
From multiple interviews, Elon has stated that he spends the majority of his time on engineering and design problems, and very little time on business, PR.
If by facts you mean "the picture that Musk's PR machine wants you to believe as facts" then yes. Unless you spend lots of time with him personally so you state that first-hand. Somehow, I don't believe in superhumans. Elon is undoubtedly smart and successfull, but he is not a Batman (or Superman, or whatever).
