We cant live any more in a world which is based on stuff and not ideas. If you want to live with the world of stuff, were all doomed.

I don't want to think about how many people have thought or still think that I'm crazy.

I don't work on a project unless I believe that it will dramatically improve life for a bunch of people.

Whatever the marketplace, if talented people are given resources, they're going to keep driving us to having better, simpler, cheaper solutions to problems.

Education, actual learning - it is hard work. It's very personal. Your parents don't teach you anything. Your teachers don't teach you anything. The government doesn't teach you anything. You read it. You don't understand it; you read it again. You break a pencil and read it again.

Invention and entrepreneurship isn't about pure technology. Most people take whatever they see in front of them and relate it to something they understand. For at least ten years after Ford started building cars, people called them horseless carriages. It wasn't obvious to call it a car. They used to call the radio 'the wireless.' Innovation is much more about changing people and their perceptions and their attitudes and their willingness to accept change than it is about physics and engineering.

As we move towards 8 or 10 billion people on the planet, there's a little less gold per capita. Each one of us will continue to be fighting over an ever smaller percentage of total resources. This is not a happy thought
