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.

It has yet to be proven that intelligence has any survival value.
