The complete opposite of Raspberry Pi, but I predict that one result of generative AI models is we will end up with over 1 million concurrent players on MUDs.

#1 Dramatic simplification of navigation and actions, making them accessible for new users

#2 Significantly better role-playing enabled through NPC characters

#3 Access & visualization medium by choice: text, narration/voice, image, video, 3D

If I had the free time this is what I would work on now. I've messed around with LLM RPGs, but the big piece is there needs to be a stored structure to get around the context model issues, or at minimum reduce costs and speed up use since we now have huge context models.
