In a hyper-connected world where average is over, there is one thing we know absolutely for sure: Every good job will require more education.

So what am I? I guess I would call myself a sober optimist...If you are not sober about the scale of the challenge, then you are not paying attention. But if you are not an optimist, you have no chance of generating the kind of mass movement needed to achieve the needed scale.

I think no country is going to be immune from the Arab awakening because the Arab awakening is driven by deep human longing for dignity, for justice and for freedom. I think that applies to young people in Saudi Arabia as much as to young people in Egypt, Tunisia, or Yemen, or Libya, or Syria. If I were in Saudi Arabia, I would be getting ahead of this and looking for ways to appreciate those aspirations and align my country with them.

What I want is natural gas to be a bridge to a cleaner energy future, not a dam against a cleaner energy future, not a dead end. To get this right, to get the most out of it, we not only have to make sure we exploit natural gas in a clean way - it's a challenge - but we also have to make sure that we are instilling and implementing all the incentives to win solar, nuclear energy efficiency that will make them continually competitive with natural gas in the future.
