An Article on Motherboard reports about Alien Minds by Susan Schneider who claiThe Dominant Life Form In the Cosmos Is Probably Superintelligent Robots. The article is crosslinked to other posts about superintelligence and at the end discusses the question why these alien robots leave us along. The arguments puts forth on this don't convince me though.
The Superintelligent Robot in My Garage, in other words. These conjectures for why ET's have to exist, but we haven't observed them yet, sound increasingly desperate and crazy. People hold on to this belief any way because the advanced ET has become a place-filler for the gods and demons we've recently believed in.
The absence of apparent intelligent life is a serious issue. It has nothing to do with believing in gods or demons, but is a real problem that we need to figure out the cause for. If the Great Filter is behind us, there's no serious issue. If the Great Filter is in front of us, then we need to be very concerned. These are deep questions that also have practical implications. The fact that the particular explanation from the article isn't a very good one is incidental.
