I really like that you mentioned machine learning. ML is a great practical application of a subset of AI. You don’t necessarily need an advanced AI DM. Sometimes you just need a tool to simplify DMing. I remember writing cellular automata that would build maps and dungeons. That’s not using ML or neural networks or anything like that, but it was code that simplified my task. People tend to think about the hype behind buzzwords and not how they are practically applied.
