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

Science fiction is the great opportunity to speculate on what could happen. It does give me, as a futurist, scenarios.

As you go out to the 2040s, now the bulk of our thinking is out in the cloud. The biological portion of our brain didn't go away but the nonbiological portion will be much more powerful. And it will be uploaded automatically the way we back up everything now that's digital.

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.

Although I'm not prepared to move up my prediction of a computer passing the Turing test by 2029, the progress that has been achieved in systems like Watson should give anyone substantial confidence that the advent of Turing-level AI is close at hand. If one were to create a version of Watson that was optimized for the Turing test, it would probably come pretty close.

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.

Mobile phones are misnamed. They should be called gateways to human knowledge.
