How soon before the NPCs in open world games are hooked up to GPT and can converse with you in character based on spoken audio from the player via a headset?

And then assume procedural generation like No Man’s Sky + Midjourney level graphics…

Get lost in an infinite Hyrule, San Andreas, Tamriel, Azeroth with infinite storylines and side quests

The part I’m excited about is the possibility of both shared Worldbuilding (procedurally generated but cross-player consistent) and private experience (like a simulator, players can shape a world based on consistently interacting with the AI in a specific way,,, eg going all the way “good” or “evil”)
