Many minds have pondered the tired, old '
Fermi Paradox' (the conspicuous lack of alien buddies out there in our humongous universe).

+ Susan Blackmore's solution to the Fermi paradox (see
her TED lecture): the necessary paradigm shifts to each kind of replicator (genes, memes, temes) are apocalyptically dangerous. Each (necessary) transition reduces the chances of a fertile planet bearing space-faring life forms; each adds an extra constant to the
Drake Equation. She speculated in "The Meme Machine" that meme's evolutionary force driving bigger brains may have overstretched the physiology of our hominid peers, driving Neanderthals extinct. Mems have also, through humans, have wiped out more genetic diversity than a mass extinction, fostered luming terrors are nuclear annihilation, or terminator style runaway AI. I'm more optimistic, seeing only the risk of delay, not unrecoverable oblivion.

+ In the BBC news article (that triggered this blog article): "Alien hunters 'should look for artificial intelligence'", Seth Shostak is interviewed as saying we should look for AI aliens, rather than flesh and bones. e.g. not just concentrating observations on biologically 'habitable' planets, but areas richest in mass and energy where only machines could exist.

So it seems the realisation may be approaching mainstream consciousness: ogling the skies for alien peers is quite clearly pointless. Not because (the conditions for) life is necessarily rare (or because of any literal religious truth), but because life (e.g. humanity) will pass through this (SETI) phase in gynaecological evolution so rapidly...
