This is a great article. I've been considering where this will head with gpt-2 dungeon master showing how far AI has come.

While I agree with the article that so far everything digital has been a noble failure, I feel there is too much discussion between AI vs humans. I think the future is in AI-assisted human DMs. Software may not be able to "entertain and dazzle" with the creativity of humans but it can help coordinate many routine tasks in any dnd game allowing the human DMs to focus their time on the components that make the adventure fun.
