What I meant by not being sure about the point was not that he was not clear in what platitudes he was trying to convey, just that I was not sure about what he was trying to say which includes what questions he was trying to raise. It provides the reader with something to think about primarily through the messiness that you noticed instead of raising questions and ideas which work off of each other; the ending simply undercuts any nuance of the AI failing to get their frustration instead building on it or changing our perspective on it.

For example, if it had ended a few sentences earlier and used that potential bit of metafiction it would be suggesting that the story we just read was or at least could be the story written by the AI for the novelist and now the AI does understand their frustration but represented itself as not understanding it. That gives us a great deal to think about and builds in a second perspective on the entire piece, the perspective of the AI. But as written that only works well with the conversation part of the story and those last few lines make it really not work at all.

Edit: I think you could make the case that the meta is utilized just as I outlined above, it kind of works with the general pretentious ass that ChatGPT is in the story, things like the mace and the general lack of preparedness of the writers kind of works with those last few lines in that context. But that raises other issues and likely has some rather ugly/messy ramifications on the whole, I think. Probably will reread it when I get home but on a quick check of a few things, strongly suspect my initial view is the the more accurate one and I am just having fun with analysis at this point.
