I think we've done a lot of not-so-smart stuff. I think we should at least start moving into the right direction, stop shouting and stop letting 'the noise' from the outer space enter freely into our computers, stop intensively process it the same way each year, putting more processing power into it every day (and being proud of it).
According to BOINC (Boinc all Project Stats) the SETI@HOME is processing 1,683.399 TeraFLOPS taking up more than 40% of all hosts. That is terrible. It is either useless (if there are no aliens) or very dangerous (if there are). BOINC has much more useful projects to participate in.
