When you can't rely on sticking a pipe in the ground, what you have to rely on is unlocking the energy and talent of all your people - men and women.

I have a daughter who is a sophomore in college and another who is in the 11th grade of high school.

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.

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.

The Arab world had a big problem of frankly venal elites. That is why these revolutions happen, because people didn't think the opportunities were being shared fairly.

Combating climate change requires government policy, and most conservatives hate the idea of more government regulation. Because they hate the prescription, they deny the diagnosis.

I think the Arab awakening has changed everything and I think a lot will depend on what people there ask of us, may be nothing, it may be a lot. I think that really depends how they find their voice and what they see as their real interest, and hopefully that would be for more schools and not more tanks.
