I am being very humble about the Arab Spring. There's kind of a competition out there, you might have noticed, of who can be the first to say the Arab Spring is going to fail. Everyone says, "I told you so, I told you so about the Muslim Brotherhood." I have no desire to tell anyone anything. I don't know. I'm just listening, watching. It may turn out all these people are right, they may be wrong. They may be right this year and wrong next year, by the way. I'm just trying to listen day to day, figure it out.

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

I am always a little skeptical on the water thing because I have been hearing that for 30 years, but one year it's going to be true. With the rising populations, Yemen could be the first country in the world, or Sana'a the first major city in the world, to run out of water, that's from Yemeni hydrological engineers and the United Nations. Sooner or later, all of these people, from 7 to 9 billion, all of them want to live like America, will be consuming so much more water that some of the societies will hit a wall without more sustainable environmental practices.

We need to become energy independent or at least aspire to that.

Hope and optimism aren't just attitudes, they are life strategies.

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.

Change your leaders, not your light bulbs.
