Sometimes people talk about conflict between humans and machines, and you can see that in a lot of science fiction. But the machines were creating are not some invasion from Mars. We create these tools to expand our own reach.

There is one brain organ that is optimised for understanding and articulating logical processes and that is the outer layer of the brain, called the cerebral cortex. Unlike the rest of the brain, this relatively recent evolutionary development is rather flat, only about 0.32 cm (0.12 in) thick and includes a mere 6 million neurons. This elaborately folded organ provides us with what little competence we do possess for understanding what we do and who we do it.

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.

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.

I'm an inventor. I became interested in long-term trends because an invention has to make sense in the world in which it is finished, not the world in which it is started.

By 2009, computers will disappear. Displays will be written directly onto our retinas by devices in our eyeglasses and contact lenses.

We only have to capture 1/10,000th of the solar energy landing on earth to completely satisfy all our energy needs.
