The true heroes - the actual researchers and engineers putting in ridiculously long hours out of pure passion and thereby making the steady stream of breakthroughs necessary to allow new technologies to flourish - rarely get any press or credit. However, there are circus ringleaders (as Elon has been accused of being), and then there are true polymaths who can both competently direct large scale engineering efforts and deal with entirely disparate realms such as corporate governance, marketing and negotiations. He may not have been getting enough sleep lately, but I think he's more the latter than the former. You don't get put in charge of revolutionary payment systems, luxury vehicles, interplanetary transport and energy storage one right after another purely by accident.
