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

By the time of the Singularity, there won't be a distinction between humans and technology. This is not because humans will have become what we think of as machines today, but rather machines will have progressed to be like humans and beyond. Technology will be the metaphorical opposable thumb that enables our next step in evolution.

Machines will follow a path that mirrors the evolution of humans. Ultimately, however, self-aware, self-improving machines will evolve beyond humans' ability to control or even understand them.

When I was a student at MIT, we all shared one computer and it took up a whole building. The computer in your cell phone today is a million times cheaper and a thousand times more powerful. What now fits in your pocket 25 years from now will fit into a blood cell and will again be millions of times more cost effective.

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.

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.

The Singularity denotes an event that will take place in the material world, the inevitable next step in the evolutionary process that started with biological evolution and has extended through human-directed technological evolution. however, it is precisely in the world of matter and energy that we encounter transcendence, a principal connotation of what people refer to as spirituality.
