The purposeful destruction of information is the essence of intelligent work.

By 2010 computers will disappear. They'll be so small, they'll be embedded in our clothing, in our environment. Images will be written directly to our retina, providing full-immersion virtual reality, augmented real reality. We'll be interacting with virtual personalities.

Those with engineering skills will build tomorrow's genius computers. But those with the ability to create knowledge of any kind will be the ones who are best able to extract great value from them. The way to create value in the age of genius machines will be to compile and disseminate knowledge that other people will find useful.

We're democratizing the tools of creativity.

By the end of this decade, computers will disappear as distinct physical objects, with displays built in our eyeglasses, and electronics woven in our clothing, providing full-immersion visual virtual reality.

So what used to fit in a building now fits in your pocket, what fits in your pocket now will fit inside a blood cell in 25 years.

All of our schools need to bring 'learn from doing' into the mainstream education, not just afternoon.
