Your heading and post are about different things. Robot or real doctors and nurses?
If I was programming a robot, I would include a way for the patient to contact a real breathing, speaking, listening human being who would observe my expression and tone of voice as I described symptoms and asked my questions, someone who would make conclusions with that information as well as the bare facts. He or she would explain the diagnoses, treatment and prognosis in terms that I could take in and understand. Robot chats usually bring you round in a circle that starts back at the beginning again without properly answering you
I don't know enough about all the individual specialists who might be able to help with every ailment I might suffer from. I rely on my GP to refer me to whoever is most suitable for the problem of the day. Since I won't be travelling (expensively) round the globe for (expensive) treatment, that will be a relatively local consultant.
