On a semi-related note, I've had a few conversations with physicians about the utility of AI in medicine, and all of them seem to be adamantly against any technology that displaces the individual doctor as dictator/hero of the medical hierarchy.
In one memorable exchange with a surgeon (and friend), I pointed out that doctors, like most other educated humans, are pretty terrible at applying statistics to any kind of complex decision-making - and I brought up your observation that doctors are limited to the knowledge/anecdotes/heuristics that fit in their own heads. Why not employ some kind of machine intelligence to at least aid in diagnosis, double-check treatment plans, prevent medical errors, etc? My friend abruptly changed the subject and began waxing poetic about how his decades of experience allowed him to glean enormous amounts of information from the mere tactile sensations of a loop of bowel in his hand during surgery. How would a machine replicate that, he asked. The conversation wasn't even about robotics.
I don't have a lot of faith that doctors - outside of a few pioneers - will begin using medical expert systems until they are forced to.
