Young people, I happen to believe, are the world's most precious natural resource. - Nicholas Negroponte

When you write a computer program you've got to not just list things out and sort of take an algorithm and translate it into a set of instructions. But when there's a bug — and all programs have bugs — you've got to debug it. You've got to go in, change it, and then re-execute … and you iterate. And that iteration is really a very, very good approximation of learning.

The change from atoms to bits is irrevocable and unstoppable. Why now? Because the change is also exponential — small differences of yesterday can have suddenly shocking consequences tomorrow.

The Internet for us was like air. It was there all the time — you wouldn't notice it existed unless it was missing.
