Space Cold War: Oh, lots of them, simultaneously. The Empire vs. the Voniensa Republic over AI rights, proper contact protocol, economics, and No Transhumanism Allowed. The Silicate Tree versus AI-slaver civilizations, with contributions from the Photonic Tree, Empire, and others. Random bits of the Rim Free Zone versus whichever states have annoyed it this week. The Leviathan Consciousness versus everyone who doesn’t want to be non-consensually hegemonized and optimized. And so on and so forth, with many more smaller ones (about which also see Enforced Cold War).
Got to pass the time somehow, I suppose.
