Why do you run SETI@home?
Brilliant. Putting all these computers to work in search of this goal was simple genious. I hope the project goes on until we find what I know is out there. There is no greater quest left than this one.
Thoughts about ETI
I believe, almost to the point of faith, that they are out there. Assuming for a moment that life could only emerge from an enviorment such as ours; carbon and oxygen based - how many planets are there in the universe that are similar to the Earth and have that same makeup? There must be millions. Of coures, on the other side of the universe, life may emerge from elements we don't even know of yet. It's almost to the point where I think it is statistically impossible for life to NOT exist out there. And knowing the relative young age of Earth, I would assume there is life out there that is much older than we are, and probably more advanced. All that we know, all that we think of our selves and our place, will be changed forever when we find them. Sure there are risks, but all great human endeavors have been that way through the centuries.
