In a way it does a good job of showing both the current strengths and weaknesses of computers. Managing the rules and stats by hand can be fun, but I have seen many recorded sessions where it is obviously a burden that a computer would be perfectly suited for.
On the other hand, aspects of D&D like face-to-face interaction and language-based free creativity are things the computer can't handle well. Although video chat is a thing. Computers can't understand language at this point so they can't manage everything for you. Of course DMing is the most fun for many people so they wouldn't want a computer to DM.
I wonder if there would be a way to translate the freedom that you get as a DM or player in terms of world creation, scenario management, and freedom of action, to an interactive video-game type experience. Maybe in VR?
