I actually think that ChatGPT could eventually become the way to play tabletop RPGs. It's not quite there yet, though. It's not the most creative writer, still often has internal consistency flaws, and of course it would have to be trained specifically on the rules of the RPG you're playing. But once it has been, it could probably act as a DM for groups that lack one. Or as a very closely coupled assistant to less experienced DMs who may need hand holding. It could even likely replace players, which could be useful for solo players who can't find a group (or, say, have incompatible scheduling).

Unlike a regular video game, the format of tabletop RPGs seems perfect for our current rudimentary AIs and the constraints are ones that they can probably handle with careful training alone. It's also a useful niche since there's no replacing the open endedness of tabletop RPGs with current technology. There's also a lot of people out there that I'm sure would like to play tabletop RPGs but just lack a group. Anyone who's played them before knows that scheduling is really hard and has killed a lot of groups. That's something an AI could help with.
