People talk about all of the issues with AI (and there are many) but I would actually like some AI help with making maps. I do a lot of TotM for exploration because I find detailed map making boring. While I'm sure others love it, and people will be able to share their creations which is awesome, I found it to be time consuming and tedious when I had to do it during COVID even if I was able to get results we enjoyed.
So for me? Have an AI give me a basic town layout based on basic options and criteria. Let me use the tools provided to then tweak the look and feel of that town to match what I had envisioned. Extending it even further, learn from previous maps I generated and modified. Ideally, if they go into a house I never imagined they'd want to go into because the PCs are always going directions I don't expect, have a real interior.
I'm sure that kind of functionality is down the road, if ever, but that would be incredible. There's other things the AI could help with of course like help filling out campaign details, but that's a separate topic.
