Let's go right to the moment where a competent doctor gets the patient treatment recommendation from Watson. He/She looks at it and instantly realizes it is junk and may actually kill the patient if followed. It has to be sooo wrong that a doctor calls this a "piece of shit", which is not common medical terminology, but highly expressive and meant to convey serious dissatisfaction in an area they have a lot of experience with. This is Theranos-level serious. IBM has been promoting something that does not work and because they have armies of experts, they know it does not work. It's lawsuit o'clock somewhere in the world.
