Even if all some AI system did was take a list of symptoms, anonymize them, suggest a diagnosis, and then take the MD's actual diagnosis, track outcomes, and compare results over time, it would be a huge advancement.

Right now, unless I misunderstand something structural about our medical system, most of the data gathered by MDs are wasted, because there is no digital record of much of it and patient privacy legalities prevent wholesale entering of symptoms and case outcomes in to any sort of freely available (inter)national database.
