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 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.

The Great Filter provides no explanation here. There are four options: early filter, late filter, multiple (early and late) filters, and no filters. In the first three cases the existence of early filters is explanation for an empty sky. (We are getting very close to the capability to build von Neuman probes though, so I'm not sure an o sky is evidence for a late filter.) In the case of no filter however, we can expect that any intelligence would start expanding into the universe at near the speed of light. So the fact that our light cone doesn't contain ...

The Great Filter dogma has a number of problems. If you start with any reasonable universe simulation model prior and sample it to get a prior probability distribution over habitable planets forming - you get lots and lots of them. You would need enormous evidence - like actually searching all of the galaxy - to overcome this prior. Furthermore, we need to factor in universe selection in the multiverse. Biophilic universes can probably engineer space-time by creating artificial new universes - effectively shaping the prior probability distribution over the entire multiverse. (even if the physics of this seem low probability, it amplifies itself from nothing) Thus, life is far far more likely than it otherwise should be, because life is a necessary component of replicating universes, and replicating universes dominate the multiverse. And finally, the entire idea of the great filter is based on an extremely specific and low probability model of future evolution of superintelligent civilization - dyson spheres and other nonsense. See my reply here. Basically entropy/temperature is computational stupidity, and advanced civilizations need to move into a low entropy environment (like the intergalactic medium), becoming cold dark matter.
