Actually there are already systems in the field that offer better results than people. I remember reading research about decision support systems doing a better job, and there's isabel healthcare , offering decision support system that works great for rare diseases as far as i know. The way they are implemented is by people entering data in an orderly fashion, both those who built the systems ,and doctors . This somewhat limits the system, both from breadth of research and data entry time at the doctor. But even with those limitations , those systems offer far better diagnoses , especially in the rare cases,than you average and even great doctor.
