I've always believed the world would be a better place if more people everywhere have a chance to shape their own future and realize their full potential. I think that is what life is about.

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.

We are entering a hyperconnected world where every boss now has more access, cheap access to cheap labor, cheap genius, cheap robot, cheap software, and then this world averages over. There is only one answer to that, and that is to get everyone as close as possible to some form of post-secondary education, it could be vocational, it can be liberal arts, it can be science and technology.

I said that more people in more places can now compete, connect and collaborate with equal power and equal tools than ever before.

Scientists tend to focus on what they don't know more than what they do know. And there are a lot of things we still don't know about the climate. But we know the difference between climate variability and climate change, and right now the amount of carbon in the atmosphere is well outside the variability pattern - and that's quite quantifiable.

I attended public school with the same group of kids from K through 12.

There's a difference between being able to make long distance phone calls cheaper on the Internet and walking around Riyadh with a PDA where you can have all of Google in your pocket. It's a difference in degree that's so enormous it becomes a difference in kind.
