I think we could use more intelligent parsers (especially for new IF players), I mean the algorithm that tries to find out what the player wants to do. [You could call it input AI.] But I don’t think this can be done with ChatGPT.
I don’t think it would work to let AI decide what the game world does in reaction to the input. [This could be called game logic AI.]
Edit: Sorry I wasn’t aware that this has been discussed excessively already.
