Someone still has to choose what to prompt and I don’t think a boilerplate “make me a marketing plan then write pages for it” will be enough to stand out. And I’d bet that the cyborg writers using AI will outcompete the purely AI ones.
(I also was just using it as a point to show how being identified as AI-made is already starting to have a negative connotation. Maybe the future is one where everything is an AI but no one admits it.)
