So I found a word in Ukrainian (and Russian) and means "undead" but sounds pretty fun when applied to an AI.

"Нежить".

But it doesn't feel like the word "undead" fits here. Any good synonyms that I don't know about?

@yura That sounds like Polish for mucosal inflammation.

I'm not sure of any words for the undead or constructs that would match AI.

@lukyan that's a second meaning, yep :)
