NATHAN MYHRVOLD: The Wealthy Should Fund Innovation. “Jeff Bezos has Blue Origin, a company that builds spaceships. Elon Musk has Tesla, an electric-car company, and SpaceX, another rocket-ship company. Bill Gates took on big challenges in the developing world—combating malaria, HIV, and poverty. He is also funding inventive new companies at the cutting edge of technology. I’m involved in some of them, including TerraPower, which we formed to commercialize a promising new kind of nuclear reactor.”
