Reacting to the headline, I understand the basic concept of medicine is you treat a patient who presents with a condition, not a condition in isolation like some kind of abstract math problem. I think it's a mistake when doctors say to each other, even as a shorthand, I have a gallbladder to deal with, when it's a real person, and the best results come from considering the whole person when pondering how to care for them and which treatments to administer, with the medicine being only a part.

You are speaking commendably from the point of view of diagnostics but from the point of view of physical operation you absolutely need that specialisation.
