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

By the 2030s, the nonbiological portion of our intelligence will predominate.

We have the means right now to live long enough to live forever. Existing knowledge can be aggressively applied to dramatically slow down aging processes so we can still be in vital health when the more radical life-extending therapies from biotechnology and nanotechnology become available. But most baby boomers won't make it because they are unaware of the accelerating aging process in their bodies and the opportunity to intervene.

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

There are downsides to every technology. Fire kept us warm, but also burned down our villages.

Our technology, our machines, is part of our humanity. We created them to extend ourselves, and that is what is unique about human beings.

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.
