The great thing about cheap natural gas, again it's cheap, and it provides a cleaner alternative to coal. But it's still a fossil fuel, and because it's still a fossil fuel, it still emits carbon.

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.

The reason that we are becoming less equal is because of the greater requirements, secure requirements, for a good job. This goes back to the '80s basically, this started changing as globalization and the IT revolution merged, and each started to drive the other.

If you don't visit the bad neighborhoods, the bad neighborhoods are going to visit you.

By 'flat' I did not mean that the world is getting equal. I said that more people in more places can now compete, connect and collaborate with equal power and equal tools than ever before. That's why an Indian in Bangalore can take care of the office work of American doctors or read the X-rays of German hospitals.

Rock stars get room keys, I get business cards.

I love America. I think it's the best country in the world. But I also think we're not tending to our sauce.
