[WH40K] Has a Tau Drone ever been corrupted by Chaos?
gpt
Not yet. At least not that we know of.

For "Not Yet":

* Tau AI technology simply isn't advanced enough. It's ability to "think" is barely more than basic programming response. Like how an insect's thinking is merely instinctive response.

* Like all AI, Tau AI is modeled after their brain and nervous system. Since Tau don't respond to warp energy, the AI doesn't either.

* Tau are powerful, but they're so tiny they most they are is a nuisance for the major factions. Chaos corrupted human AI because Dark Age humanity could crush them.

For "Not that we know of":

* It's happened but the Tau are keeping under wraps. They know how humanity's empire crumbled and they don't want to set off a panic.

* The Tau haven't realized its Chaos corruption. They have no psykers and their technology barely even interacts with the warp. An AI could have been corrupted so they just destroyed it thinking it was malfunctioning.

* All Tau AI are already corrupt. But the Chaos Gods (likely Tzneetch) are keeping the AI docile for the time being. That way, they can eradicate the Tau in one go if it ever comes to it.
