It is very hard to get good medical diagnosis. Doctors are overworked and can barely spend more than 10 minutes thinking about you. People with long complex medical histories get completely fucked over, so basically these social tasks already are not being performed properly by humans because the humans doing it are stretched way too thin.
AI is going to quickly surpass the quality of medical diagnosis by doctors, at which point hopefully people can see a the right kind of specialists faster and get treatment quicker.
