The extension of life beyond Earth is the most important thing we can do as a species.

I really do encourage other manufacturers to bring electric cars to market. It's a good thing, and they need to bring it to market and keep iterating and improving and make better and better electric cars, and that's what going to result in humanity achieving a sustainable transport future.

Trying to read our DNA is like trying to understand software code - with only 90% of the code riddled with errors. It's very difficult in that case to understand and predict what that software code is going to do.

Constantly seek criticism. A well thought out critique of what you're doing is as valuable as gold

Boeing just took $20 billion and 10 years to improve the efficiency of their planes by 10 percent. That's pretty lame. I have a design in mind for a vertical liftoff supersonic jet that would be a really big improvement.
