When Artificial Intelligence TRULY arrives... a lot of things will change... and RPGs (if the still exist in a somewhat relevant form) will not need a DM no more.... but we are still faaaaar from that...
On the contrary, when AI is incorporated into D&D, we DMs won't need players anymore.![]()
I am reminded of a quote by one of the great minds of computer science, Edsger W. Dijkstra:
"The question of whether Machines Can Think... is about as relevant as the question of whether Submarines Can Swim."
That aside, though, there are two other questions which I think remain relevant.
1) Display and interaction technology - there are a great many things that a computer could, even with today's computer science, do to assist an RPG. However, the display and interaction technology required to make use of the potential is still prohibitively expensive. The Microsoft Surface, a good example of the start of such things, is a $10k+ item. But we could imagine these things coming down in price, if only someone finds a mainstream application of the technology.
2) RPGs are a niche hobby. There's a limited number of players for any particular game, but each particular game requires hefty programming to support it. Economically, doing a whole boatload of development for a small market is a losing proposition. I am not convinced this is ever going to change.
