Despite the fact there are more billionaires than ever, it's funny how small the group of bold innovators are. It always seems to be the same few people.
I'd argue that Bill Gate's work has a better return of investment for society.
IMO, we need both types - Gates' work improves society in our current world, while Musk and Branson's investment kickstart the scientific and technological advances needed to further our civilization.
No, it’s different people doing it, but the same few people funding it. Like VC.
