Self-driving cars are the natural extension of active safety and obviously something we should do.

I was born in Africa. I came to California because it's really where new technologies can be brought to fruition, and I don't see a viable competitor.

If we drive down the cost of transportation in space, we can do great things.

Technology leadership is not defined by patents, which history has repeatedly shown to be small protection indeed against a determined competitor, but rather by the ability of a company to attract and motivate the world's most talented engineers.

The space shuttle was often used as an example of why you shouldn't even attempt to make something reusable. But one failed experiment does not invalidate the greater goal. If that was the case, we'd never have had the light bulb.

There are really two things that have to occur in order for a new technology to be affordable to the mass market. One is you need economies of scale. The other is you need to iterate on the design. You need to go through a few versions.
