It's OK to have your eggs in one basket as long as you control what happens to that basket.

An asteroid or a supervolcano could certainly destroy us, but we also face risks the dinosaurs never saw: An engineered virus, nuclear war, inadvertent creation of a micro black hole, or some as-yet-unknown technology could spell the end of us.

I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy.

Funded by the government just means funded by the people. Government, by the way, has no money. It only takes money from the people. Sometimes people forget that that's really what occurs.

I don't spend my time pontificating about high-concept things; I spend my time solving engineering and manufacturing problems.

I've actually made a prediction that within 30 years a majority of new cars made in the United States will be electric. And I don't mean hybrid, I mean fully electric.

I think the high-tech industry is used to developing new things very quickly. It's the Silicon Valley way of doing business: You either move very quickly and you work hard to improve your product technology, or you get destroyed by some other company.
