Elon Musk is not a superman. He is a good businessman and a super-optimist who hit it big in the dot-com boom and rather than retiring with a bevy of bathing beauties as I'd have done, he took that money and plowed it into an insane dream: That electric cars could be fun to drive and good for the environment and we could power them from the sunlight hitting our roofs. Then SpaceX. And proving that he's not infallible or a superman, there's the Boring Company.
