I've experimented with AI DM-ing. There are pros and cons. Like the author indicates, it reduces the cognitive load considerably. NPCs names, personality, description, and dialog can be generated wholesale. Place descriptions, etc, are fundamentally better than what I can improvise on my own. You can, today, simulate DnD using an LLM, however, you will run into some issues. You will blow out the context window and lose important information. In particular, inventory, gold, key plot points, and HP will cease to exist as the story progresses. It will be forgotten before the players forget about it and then you'll have conflicting versions of reality with no easy way to resolve it - short of keeping track by hand or incorporating it into the world diagetically. Acting as avatar for the LLM is rather fun. Converting their actions into subsequent prompts and then reading the responses back is genuinely enjoyable. I hope it gives the players a sense of actually participating in a DnD game, but I'm not sure - I've only DM-ed this way. Ideally, there would be built in mechanisms for tacking these facts. I'd pay money for that. The benefit would be running an ad hoc game for friends with zero preptime. That's something that's otherwise unavailable to me.
