For emerging diseases, advanced malingering, etc, you definitely need real life actual breathing human beings. Otherwise, sure, physicians are just as theoretically replaceable as any information-as-a-service workers might be.
Edit: I didn't realize this was even a controversial statement to make. First, to be clear, when I'm in the hospital and say "doctor" I'm usually thinking non-surgeon, as I am here. Second, you will always need supervision of the machines, just not 1-to-1 supervision. Not every interaction brings up ethical questions, for example. Sometimes someone really just has a viral URI.
