Doctor: IBM's Watson supercomputer has diagnosed your symptoms. The computer just ordered the meds you need. They will be delivered in an hour by drone. Dilbert: Looks like your job as a doctor is becoming obsolete. Doctor: Ha ha! No. You still need a doctor and a nurse to make the system work. For example, the computer can't read its own screen and speak those words to patients. Dilbert: Actually, it can. Doctor: But the computer doesn't have a nurse. Dilbert: What does the nurse do? Nurse: I stab him if he tries to do more than read the screen.
