Artificial Intelligence: Well, while the term in-universe is rather more all-encompassing, the fictional trope is defined as meaning those systems which are sentient (gah, damn you badly written science fiction!), self-aware, and capable of independent thought and reason. Those ones, they call digisapiences.
And there are a heck of a lot of them, yes, enough that you aren’t going to be able to walk down the street (or stick your nose out onto the network) without running into a few. Certainly far too many to name on any sort of individual basis. And for the most part, they’re pretty much “just folks”, if very smart, fast-running folks.
Which is not so much to talk about recursively self-improving seed AI, who are pretty much just weakly godlike superintelligences, with all that that implies.
Also of note is the Photonic Network, an entire Great Power-level civilization of advanced artificial intelligences, and the Silicate Tree, a loose alliance in the Galith Waste of renegade digisapiences from assorted slaver civilizations. Having given them ample reason to be hostile in the past, meat intelligences travel off the main routes through the Waste at their own risk.
