Most children in the world go to schools in two shifts, there's a morning shift and an afternoon shift.

I'm not against paying at all. What I'm against is the complexity of paying. And you very often go to a website and you try to click on something and sometimes it will even say it's free, but you have to fill out this form.

When things are digital, they're all 1's and zero's, and so they commingle in ways we didn't anticipate and you could do things that were not like publishing or television, or computers, but were some intersection of those and that got known to be convergence, so between the switching, or trading of places and the convergence, you have today's media.

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.

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.

I'd like to describe a sort of life 20 years ago as being a fried egg. There was a yolk and a white and the white was maybe work, and the yolk was life. Today, it's more of an omelet. It's more mixed and it's more interspersed and I think that that's a more interesting state of being and for some people, they'll say well I want the crisp, fried egg approach to life.

The process of debugging, going an correcting the program and then looking at the behavior, and then correcting it again, and finally iteratively getting it to a working program, is in fact, very close to learning about learning.
