So I couldn't find the specific post I was thinking of off hand, and there seems to be about a dozen or so hits on various forum-type sites like Quora/Reddit etc. So... yeah I don't know, maybe it is real? But there has been an instance of someone using an LLM to make a story about an LLM saving their life. So maybe this one is real. Maybe it is not? Who knows. Reality is kind of mushy these days.
Additional notes here, the author of the article in this topic clearly indicates on her page that she writes alongside "Taylor Script", her AI counterpart. So now the line is even more explicitly blurred. An AI definitively was involved in the creation of this content... so now the question is, to what degree does the content relate back to real world events? Only the author knows I guess.
