Elon Musk risked $160M of his $160M fortune on SpaceX and Tesla (and Solar City). Most people with $160M do absolutely nothing with it of any consequence to humanity. If part of Musk's ambition is to turn his $160M into $160B I'm personally all for it. In the process of fulfilling his own ambitions he's pushing the entire race forward. The long term benefits of switching to renewable energy are be measured in trillions. Human investment in space travel will ultimately be more valuable than Earth itself.
