>Can they do that?
The (strictly fan based) idea is that, despite lacking a warp connection, AIs are somehow more susceptible to chaotic corruption, which is why the Imperium uses so few advanced computers, etc. Of course, in every case the AI was purposefully subjected to dark rituals and the like. It doesn't just 'happen.'
A recurring theme is that the Imperium's brutal living conditions are what drive people to Chaos, so content people would be way less susceptible.
That being said, Chaos isn't intentionally trying to destroy the Imperium, and presumably they would not intentionally try to destroy the Culture. The Chaos Gods can flat out trigger daemonic incursions and warp storms and the like if they feel like it (for example, Nurgle punished a world that eradicated all natural disease by ruining it and flooding it with a daemonic incursion), though. Chaotic humans trying to do screwed up stuff in rituals and the like are mostly doing it to get their gods' attention, because its important to remember the Chaos Gods really are gods, however you care to define a god -- at the very least, as beings that can ruin planets at will.
