The most awesome fic I could come up so far is: Elon Musk, in running a crusade to send humanity into chaos out of spite for being forced to acquire Twitter. Through some of his insiders in OpenAI, they use an advanced version of ChatGPT to impersonate board members in conversation with each other in private messages, so they individually believe a subset of the others is plotting to oust them from the board and take over. Then, unknowingly they build a conspiracy among a themselves to bring the company down by ousting Altmann.
I can picture Musk's maniac laughing as the plan unfolds, and he gets rid of what would be GPT 13.0, the only possible threat to the domination of his own literal android kid X Æ A-Xi.
