> Like in my experience the best part of d&d is the dungeon master who knows their friends making a story and details specifically for fun and the fun of the group.

Sure.

There are two reason why I can think of someone making a Dungeon Master LLm.

One is that when there is no cake we eat bread.

Don't get me wrong. I'm a DM, and I love playing d&d with my friends. I totally agree with the sentiment you are sharing. But people who are willing, and able to DM for others are not evenly distributed. There is a lot more people who would like to play TTRPGs than people who is willing to step into the DM role.

So in that sense think of this as a substitutions for those games which would not happen otherwise, because they don't have a DM. Or the only person who would DM them is an ass. Or their DM has burnt out.

Is some game better than no game? Sometimes. Depends on how good that game is. And we won't know how good the substitute can be without trying. Heck maybe more people will play, and they will realise how easy is to DM actually.

The other reason is the sheer challenge of it. Dnd has a lot of rules. There are the obvious ones you can read in the book. But there are also un-written rules. Like object-permanence. If a goblin steals a diamond ring from us, and we slay them within minutes they damn well have the diamond ring on their bodies somewhere. If three displacer beasts ambush us and we slay 2 there damn well be 1 more accounted for in some sense.

There are also "story-writing" rules. If we went through hell and high-water to obtain an arrow of dragon slaying after the blacksmith told us about the legend of it, he better not just pull one out of his ass the next time we see him. If the whole lore of goddess X is that they are kind and caring then they should better be at least not cruel when we meet them. These are all hard for an LLM. They are also easy for a human to evaluate. Because we just feel when they are not right. Therefore it is a good challenge to evaluate how good we are at this "making a bucket of sand smart" task.
