For that I think we have to study Elon's brain when he is free from his ventures. His trajectory looks like of a perfect brain/mind that never fails to delivery even in extreme pressures. By the way he also has photographic memory so that helps.
Those are the important words. Never underestimate how much luck and chance factor into success, being in the right place at the right time and so on. Musk has done well, but studies show that corporate success only very loosely correlated with CEO skills (30%) and mostly luck.
So, no, he's not a super-man with a perfect brain, although I expect you'd still have a hard time persuading him to part with it for 'study' ;)
