At the start, we're all brilliant. We grab, we push, we drop, we reach. We stumble around and soak up our environment. We learn through experimentation and play.

More is learned in our first five years than all the years thereafter. We're super-charged learning machines. We're geniuses, every one of us.

Then we go to school. What once was play becomes structured routine. What once was our own becomes adult expectation. We're asked to learn what we cannot touch. We study our math, our grammar, without a reason why.

Some have tried to make these abstract lessons fun. Men like Seymour Papert and Alan Kay used computers to teach children the language of thought.

But their efforts never reached the mainstream because creative adults were needed. Most kids on their own lost interest without a guiding hand.
