There ought to be something very special about the boundary conditions of the universe and what can be more special than that there is no boundary?

I've noticed that even people who believe in fate look both ways before crossing the street.

It [AI] would take off on its own and redesign itself at an ever increasing rate. Humans, who are limited by slow biological evolution, couldn't compete and would be superseded.

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

It matters that you don't just give up.

If it [the universe] was expanding fairly slowly, the force of gravity would cause it eventually to stop expanding and then to start contracting. However, if it was expanding at more than a certain critical rate, gravity would never be strong enough to stop it, and the universe would continue to expand forever.

The life we have on Earth must have spontaneously generated itself. It must therefore be possible for life to generate spontaneously elsewhere in the universe.
