For me, if I want to go for breadth (quantity), AI is fine. For depth (quality), I have to come up with it or commission someone really skilled at their work.
I take Elder Scrolls II: Daggerfall as an example. The massive scale of its world map was ultimately procedurally-generated (i.e. AI). The locations important to the main quest was hand-crafted and generally of better quality.
I think I’ll use AI to keep track of the lore accurately, if I were to ever write a story. By the way, procedural generation isn’t related to AI. It is more and less related to functions like the Perlin noise generator, and it’s different variants.
Unfortunately, in my experience, AI is bad at remembering stuff like that. It’s not a database, it’s just a text generator.
Transformers have the potential to recall context. Pair it with a knowledge base software modified for writing stories and world-building, and it would boost productivity. Index-based search engine is inferior, because although the search works, users have no idea about what type of technique is being used behind - is it pattern-matching? Is it text-distance? Or vector-based?
There is a difference between AI in general and LLM’s, a subset of AI. Text generators like ChatGPT are the latter.
