I don't think I've had a doctor that is much better than a robot.
Also 90% of the time that I've been to the doctor (which is probably only around 10 times) I've merely told him my symptoms and he prescribed me a drug. There are computer programs that are better than most doctors at matching the symptoms to the actual cause, but they are not used, to my understanding, because then if someone got seriously ill or died, who would you sue? These are ridiculous issues, but they exist anyways. I think robotic practitioners could easily be better than most doctors, as sad as the case may be.
