I could either watch it happen or be a part of it.

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

You could power the entire United States with about 150 to 200 square kilometers of solar panels, the entire United States. Take a corner of Utah... there's not much going on there, I've been there. There's not even radio stations.

I want to make rockets 100 times, if not 1,000 times better. The ultimate objective is to make humanity a multiplanet species. Thirty years from now, there'll be a base on the moon and on Mars, and people will be going back and forth on SpaceX rockets.

There are some important differences between me and Tony Stark, like I have five kids, so I spend more time going to Disneyland than parties.

Some people don't like change, but you need to embrace change if the alternative is disaster.

I'd like to dial it back 5% or 10% and try to have a vacation that's not just e-mail with a view.
