"Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out, But once we spread out into space and establish independent colonies, our future should be safe."

Do you ever wonder how much deeper the ocean would be without sponges?

There is a very real danger that we will kill everything on this planet now that we have the technological power to do so.

Only time - whatever that may be - will tell.

I'm here to chew gum and kick some ass, and I'm all out of gum.

Maybe I'm being a bit harsh on philosophers, but they have not been very kind to me... I have been variously called nominalist, an instrumentalist, a positivist, a realist, and several other ists. The technique seems refutation by denigration: If you can attach a label to my approach, you don't have to say what is wrong with it... I am sure that Einstein, Heisenberg and Dirac didn't worry about whether they were realists or instrumentalists.

When something is made idiot proof, they will just make better idiots.
