I feel very strongly that SpaceX would not have been able to get started, nor would we have made the progress that we have, without the help of NASA.

We have this handy fusion reactor in the sky called the sun, you don't have to do anything, it just works. It shows up every day.

The reality is gas prices should be much more expensive then they are because we're not incorporating the true damage to the environment and the hidden costs of mining oil and transporting it to the U.S. Whenever you have an unpriced externality, you have a bit of a market failure, to the degree that eternality remains unpriced.

To our knowledge, life exists on only one planet, Earth. If something bad happens, it's gone. I think we should establish life on another planet-Mars in particular-but we 're not making very good progress. SpaceX is intended to make that happen.

With artificial intelligence we are summoning the demon.

I think it is possible for ordinary people to choose to be extraordinary.

Failure is an option here. If things are not failing, you are not innovating enough.
