Health care bots are only as good as the data and doctors they learn from

The number of tech companies pursuing health care seems to have reached an all-time high: Google, Amazon, Apple, and IBM's Watson all want to change health care using artificial intelligence. IBM has even rebranded its health offering as "Watson Health -- Cognitive Healthcare Solutions." Although technologies from these giants show great promise, the question of whether effective health care AI already exists or whether it is still a dream remains. As a physician, I believe that in order to understand what is artificially intelligent in health care, you have to first define what it means to be intelligent in health care. Consider the Turing test, a point when a machine becomes indistinguishable from a human. Joshua Batson, a writer for Wired magazine, has mused whether there is an alternative measurement to the Turing test, one where the machine doesn't just seem like a person, but an intelligent person.
