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 universe is a big, big place. It also becomes isolated relatively fast due to accelerating inflationary effects. There will probably be many intelligences out there even our most distant descendants will never meet.
Ultimately though you're making assumptions about the prior distribution of intelligent life which isn't warranted with a sample size of 1.
An extremely low prior distribution of life is an early great filter.
