I know I post a lot about Elon Musk and Tesla, but how you can you not like this guy's vision? Talk about always looking for a homerun - what he's been able to accomplish is simply incredible. This is a long article, but it's worth the read.
Musk is someone who says he wants to influence the future of humanity. He will tell you so at the slightest prompting, without so much as flinching at the grandiosity of it, or the track record of people who have used this language in the past. Musk enjoys making money, of course, and he seems to relish the billionaire lifestyle, but he is more than just a capitalist. Whatever else might be said about him, Musk has staked his fortune on businesses that address fundamental human concerns.
