When we talk about power transition, we often talk about the rise of Asia. It really should be called the recovery or return of Asia. If we looked at the world in 1800, you'd find that more than half of the world's people lived in Asia and they made more than half the world's product. Now fast forward to 1900: half the world's people -- more than half -- still live in Asia, but they're now making only a fifth of the world's product. What happened? The Industrial Revolution, which meant that all of a sudden, Europe and America became the dominant center of the world. What we're going to see in the 21st century is Asia gradually returning to being more than half of the world's population and more than half of the world's product. That's important and it's an important shift. But let me tell you a little bit about the other shift that I'm talking about, which is power diffusion.
