In other words, LLM's are, in the technical sense defined by Harry Frankfurt, bullshitters.

The essence of bullshit (as he defines it) is that it is neither truth nor lie but rather unconcerned with veracity altogether. A bullshitter wants to appear smart, or convince others to agree with them, or some other conversational objective. Bullshit statements may or may not ultimately turn out to be true, but the thing that makes them bullshit is that the bullshitter didn't actually know when they said it.

Hence I propose a far more succinct term to describe the phenomena at hand. A far more accurate terminology than the presently vogue "hallucinating": AB. Artificial Bullshit.
