ML models 'learn' by generating non-human-readable arrays of weights, that's a little pixie-dusty. But it's use there is narrow, in a supporting role. My comment was about the core 'making radiant quests feel tailored to you' thing. It woulf still be a set of tables with fillable blanks, it's structure and content decided by humans with a little random or maybe AI-gen content dropped here and there to add variety. Otherwise it won't communicate the resulting quest to the system.
