I also wonder why so much attention is paid to Musk’s scientific “genius”; he is an entrepreneur/venture capitalist who happens to be in tech and bet big at the right time. He could equally be in the poor house with so many other very smart people whose gambles did not pay off. Why do we call these billionaires "tech bros" when, in fact, they're high stakes gamblers, visionaries, who, right place, right time, founded great companies?
