Watson isn't a replacement for the physician. It's a physician's extender, a tool that allows a physician to "see" more patients in a day and provide diagnostic results in a more timely manner. The physician will still be the one responsible for the final judgment call.

BTW, it would have been nice if the journalist had bothered to consistently spell the doctor's name correctly (it's Siegel, not Siegal).
