I'm sure the universe is full of intelligent life. It's just been too intelligent to come here.

Our lifetime may be the last that will be lived out in a technological society.

Sometimes I think we're alone in the universe, and sometimes I think we're not. In either case the idea is quite staggering.

I have a fantasy where Ted Turner is elected President but refuses because he doesn't want to give up power.

This is the first age that's ever paid much attention to the future, which is a little ironic since we may not have one.
