Never before in the history of the planet have so many people, on their own, had the ability to find so much information about so many things and about so many other people.

At the end of the day, no amount of investing, no amount of clean electrons, no amount of energy efficiency will save the natural world if we are not paying attention to it - if we are not paying attention to all the things that nature give us for free: clean air, clean water, breathtaking vistas, mountains for skiing, rivers for fishing, oceans for sailing, sunsets for poets, and landscapes for painters. What good is it to have wind-powered lights to brighten the night if you can't see anything green during the day? Just because we can't sell shares in nature doesn't mean it has no value.

It created a global platform that allowed more people to plug and play, collaborate and compete, share knowledge and share work, than anything we have ever seen in the history of the world.

What if we're wrong and there is no climate change? Well, by doing everything possible to address it, we will still use less water, stimulate new energy savings and, in time, money-saving technologies, enjoy cleaner air, and preserve more forests and trees and animals.

The hidden hand of the market will never work without a hidden fist -- McDonald's cannot flourish without McDonnell Douglas, the builder of the F-15. And the hidden fist that keeps the world safe for Silicon Valley's technologies is called the United States Army, Air Force, Navy and Marine Corps.

Even if America tomorrow - and it won't happen overnight - but if we did reduce our demand for gas and natural gas and crude oil by a significant degree, that does have an exponential effect on producers in the Middle East, everything else being equal. But if China's demand is growing and India's demand is growing, they are not going back.

I think that competition will exist even if we discover more oil. We're never going to know how much we have, or how long will it last. You are always going to want to have diversity of supply. I think the Middle East will remain a region of competition, of global competition, fighting for a long time.
