Within a few decades, machine intelligence will surpass human intelligence, leading to The Singularity -- technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.

Supercomputers will achieve one human brain capacity by 2010, and personal computers will do so by about 2020.

Our intuition about the future is linear. But the reality of information technology is exponential, and that makes a profound difference. If I take 30 steps linearly, I get to 30. If I take 30 steps exponentially, I get to a billion.

Does God exist? Well, I would say, 'not yet'.

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

It is doubling now every two years. Doubling every two years means multiplying by 1,000 in 20 years. At that rate we'll meet 100 percent of our energy needs in 20 years.

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.
