A lot of what ai is good at is very useful for automating massive state surveillance programs. AI could monitor live audio and video communication for problem phrases, for example.

Making authoritarian rule easier and cheaper is a very valuable capability to elites, though detrimantal to the world.

I think the main effect of ai will be continuing this deadly trend of power consolidation that we've seen since maybe the mesolithic. The power of information will be conslidated in fewer and fewer ai-oligarchs, allowing ever more intrusive states to control more people more precisely.
