Trope-a-Day: Gendercide
Gendercide: Happened, incompletely (two-thirds of the female population killed), to the shan kari, when their learning robots generalized their anti-self-replication police-code to things that weren’t robots, and therefore concluded that it was necessary to wipe out the female of the species due to their built-in factories for making more of themselves.
Today, the Shan Kari Confederacy is known for its skewed sex ratio, its extensive use of forced-growth cloning, and its extreme hostility towards robotic technology and digital sophonts.
