@letthewatersroar@toot.cafe the Culture series is a bunch of books written by Iain M. Banks centring around a society called "the Culture", a post-scarcity anarcho-communist bunch of AIs, aliens, and humans
The main theme is how the rather idealistic Culture gets along with other societies who don't share their ideals
Also, snarky AI warships-in-all-but-name shittalking amongst themselves
