When AI approximates Machine Intelligence, then many online and computer-run RPGs will move towards actual RPG activity. Nonetheless, that will not replace the experience of 'being there,' any more than seeing a theatrical motion picture can replace the stage play.
Gary GygaxThere is no winning or losing, but rather the value is in the experience of imagining yourself as a character in whatever genre youโre involved in, whether itโs a fantasy game, the Wild West, secret agents or whatever else. You get to sort of vicariously experience those things.
Gary GygaxYou are not entering this world in the usual manner, for you are setting forth to be a Dungeon Master. Certainly there are stout fighters, mighty magic-users, wily thieves, and courageous clerics who will make their mark in the magical lands of D&D adventure. You however, are above even the greatest of these, for as DM you are to become the Shaper of the Cosmos. It is you who will give form and content to the all the universe. You will breathe life into the stillness, giving meaning and purpose to all the actions which are to follow.
