What's wild is that he could take his billions and retire to a private island for the rest of his life, but he seems to spend a great deal of time working on large difficult projects which further humanity's place as a species. I.e. shifting humanity to renewable power, engineering the first reusable rockets, worldwide internet and cellular phone communication, colonizing other bodies in the solar system as backup civilizations, and you've got to wonder why with the way he's vilified. Paints an interesting picture as to why other billionaires aren't interested in grand projects. Edit: downvoting this comment just reinforces my impression.
