in answering the "are we alone?" question, someone stated that since there are billions and billions of stars there are many technical civilizations in the Milky Way. Gotta luv it!

Not that I think there are any other ET technical civs in the Milky Way, I do agree with the new paradigm folks that looking for signs of trans-human (sic) artifacts makes more sense than the Star Trek style 'just like us but they look funny' school of thought looking for radio & optical beacons. I feel sorry for Paul Allen wasting those tens of million$ on his array. Hope they do some serendipitous science. On the other hand, it would be wicked embarrasing NOT to look and miss an obvious signal.
