In Uruguay, the President of the country announced that this would be his legacy, "One laptop per child."

There is a belief that children drop out of school because they're needed by their families to work, or the little girls are needed to take care of younger siblings. It turns out that's not really true.

Computing is not about computers any more. It is about living. Whatever big problem you can imagine, from world peace to the environment to hunger to poverty, the solution always includes education, ... We need to depend more on peer-to-peer and self-driven learning. The laptop is one important means of doing that.

Taxes will eventually become a voluntary process, with the possible exception of real estate - the one physical thing that does not move easily and has computable value. The US has a jump-start on the practice, in that 65 percent of local school funds come from real estate taxes - a practice Europeans consider odd and ill advised. But wait until that's all there is left to tax, when the rest of the things we buy and sell come from everywhere, anywhere, and nowhere.

When we go to school, very often, we don't see that passion because the way school is run, the disciplinary nature of it and the rote learning are so, sort of, offensive actually, that children sort of lose that passion more often than not.

Giving the kids a programming environment of any sort, whether it's a tool like Squeak or Scratch or Logo to write programs in a childish way - and I mean that in the most generous sense of the word, that is, playing with and building things - is one of the best ways to learn.
