Global Possibilities sums up this new Elon Musk Interview well:
“As Musk says in the interview, when he was in college he came to the conclusion that a few things would have a huge impact on humanity: the development of the internet (giving our civilization a kind of nervous system, so that any part of the system can know everything that is happening anywhere else and communicate with any other part), clean energy (both production and ways to use it — if you have clean electricity but transportation still uses oil, that doesn’t work), and making life multi-planetary. He got involved in all those areas, sometimes simultaneously and while putting all his personal money into his projects, rather than develop another social network or a better way to deliver ads next to search results or whatever, which is what a lot of other really smart people are doing these days.”
