I've seen start-ups change an industry and challenge huge companies. We saw Tesla change the auto industry, Skype changed the long-distance carriers, and Hotmail changed the post office. Huge things are happening out there, over the last forty-five to fifty years. So much improvement, thanks to the private sector.

I always describe these entrepreneurs as heroes. Heroes are our past, the people we look back on and say they did great things. But superheroes are our future - whether they are industrialists, leaders of societies, or revolutionaries. They are focused on the future. We need to find some superheroes.
