I run the S.E.T.I. client because I *firmly* believe that there's other life out there. Wouldn't it be so cool to find out that we weren't alone? It would be an awful waste of space if there weren't other life out there in this universe or neighboring galaxy.
Maybe I watch way too much Star Trek for my own good, but I've seen so much of their technology back then when it first hit the airways, now has become science fact.
But I'm not sure if the general public is ready to be contacted from other worlds. You SETI users know what I mean here.
