Thanks for this article. As the creator of the No AI badge now being used by a number of Medium writers, it's good for me to know what we're up against. Our stance is that people don't want to pay $5 a month to read something a machine wrote; they want to know that the thoughts included in a story and the emotions evoked by it are human. So, for me just knowing that there are other kinds of AI behind the scenes, which presumably are not used to write stories on Medium, helps me to distinguish between what might be good and what I declare is not. By the way, what other kinds of AI are there?
