I find SETI fascinating. Given the number of planets that are
capable of supporting life, I think it would be extremely arrogant
of us to assume we are the only intelligent life form in existence.
I doubt we'll find ET intelligence in my lifetime, but we won't ever
find it if we don't at least look!
