I don't use ChatGPT and don't plan to. For me, part of the fun of running games is being creative and doing the work of coming up with stuff myself. I don't have as much of an issue with ChatGPT as with machine generated images, so that's not why I avoid it. I just think the creative work is part of the experience, and us humans can also do that far better than a computer program. ChatGPT can't easily draw on campaign-specific themes and symbolism, can't foreshadow the greater mysteries going on. I mean, it likely can if specifically prompted to, but then you're still doing most of the work myself.
And if I want to randomly generate something... Well, we're all into TTRPG's; that's what dice are for. (Or tarot decks. I have too many of those. They're just so pretty and I keep hoarding them.)
