The Culture Series
Human created ASI have had a notable place within the galaxy for a couple thousand years now. The premises built into these ASI systems made them match the archetype of the hyper aggressive feminine.

You might ask, AI managed eugenics program to perfect the human species? Absofuckinglutely. Is The Culture's definition of perfection really perfect.... that's debatable.
