I personally do not think that Musk is a great personality if seen from the social side, but without doubt he pushed things forward where others failed to provide ideas for the future.
He invented PayPal when we were stuck with old money, he started SpaceX to challenge NASA to make space flights more accessible and last but not least Tesla could be seen as responsible for the latest rush in EVs.
I can't think of another person, neither Bezos, Nadella and for sure not Mr. Cook, who might come up with the big next thing.
