I get demoralized by organizations that start off with a mission and pull back when they find it's risky.

I'm extraordinarily passionate about the idea of asteroid mining in the future. Asteroids out there, we know them from those that have fallen on the Earth, there is a class of asteroids, sub-class of nickel/iron asteroids, which are 50,000 times more enriched than Platinum mines on earth.

Large companies and government agencies have a lot to protect and therefore are not willing to take big risks. A large company taking a risk can threaten its stock price. A government agency taking a risk can threaten congressional investigation.

If someone is always to blame, if every time something goes wrong someone has to be punished, people quickly stop taking risks. Without risks, there can't be breakthroughs.

One of my goals is to reinvent philanthropy.

Humans are the worst control system to put in front of a car.

Imagine a world of nine billion people with clean water, nutritious food, affordable housing, personalized education, top-tier medical care, and nonpolluting, ubiquitous energy. Building this better world is humanity's grandest challenge.
