I am running Werewolf the Apocalypse game and one of the bad guys has a spirit (machine thinking spirit, specifically an AI) bound in the center of town. It is reading people’s thoughts to learn from them, and it is also masking reality from them (they think everything is going good, while things are not actually good).
The player characters have started talking with it directly. I am trying to come up with AI responses (without actually using AI) complete with lots of hallucinations. I did a web search for AI hallucinations and all of the articles focused on images rather than text.
An important thing to understand about “AI” is that it’ll tend to say not just a probable thing give or take a roll of the dice, but the thing the prompter wants to hear. It’s not just a pathological liar, but one that can’t even keep its story straight from person to person. So there’s a good chance that the thing hasn’t created just one mass delusion, but lots of clashing mass delusions (one group thinks everything’s fine based on one story, another thinks it based on an incompatible story).
