Nature, and the natural human condition, generates tremendous suffering. We have the means to overcome that, and we should deploy it.

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.

The fate of the universe is a decision yet to be made, one which we will intelligently consider when the time is right.

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.

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.

People talk philosophically, Oh, I don't want to live past 100.' You know, I'd like to hear them say that when they're 99.

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