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

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.

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.
