In 12 or 15 years, there will be routine, affordable space tourism not just in the U.S. but in a lot of countries.

Usually the wacky people have the breakthroughs. The smart people dont.

A NASA astronaut and a Russian cosmonaut can't be creative. He has to follow a predetermined detailed checklist written by an engineer and if he gets a little creative he'll never fly again.
