I'd love to know if the conversational training set includes documents where the AI throws its hands up and goes "actually I have no idea". I'm guessing not.
There's also the problem of whether the LLM would learn to generate stories where the AssistantBot gives up in cases that match our own logical reasons, versus ones where the AssistantBot gives up because that's simply what AssistantBots in training-stories usually do when the User character uses words of disagreement and disapproval.
