Mapping is a data collection/sanitization and content moderation problem. You need a lot of data, much of it user-submitted, and you have a lot of bad actors constantly trying to feed in bad data. I don't see where AI comes in here except maybe for route optimization, which is a tiny percentage of what a mapping app actually does. A mapping app is mostly just a huge database of incredibly useful info that needs to be true (and LLMs cannot help there, they just make shit up).
