I've got my doubts about the search for intelligent life out there - mainly due to the fact that we have plenty of intelligent life on earth, yet haven't really found a way to have meaningful intelligent communication with them - life forms that share the exact same conditions as us as opposed to who-knows-what out there. For all the studies done on dolphins / primates / birds that have shown them to be very intelligent by many measures, studies that have shown they have very intricate communications systems, we still seem to be no closer to having anything resembling intelligent conversation similar to what happens in most people's daily lives.
