Stop the nurses before it's too late

How is Watson going to take a history or perform a physical examination? That's at least 80% of the diagnostic "algorithm" right there. The rest is narrowing the differential with appropriate investigations if there remains significant uncertainty.

Part of what the IBM team is working on is pairing Watson's analytical AI capabilities with advanced speech recognition to produce an expert system in which the computer would be able to query and respond to a human client in a conversational style, so history-taking by a machine might still be plausible in the future (think Star Trek :) ). As for performing the physical exam, integrated robotics and diagnostics might be able to accomplish that role when combined with the other expert systems. What we think of as impossible/implausible today might very well become reality in the future, and not necessarily the distant future either.

It'll be interesting to see - eventually someone will try to figure out automated diagnoses some day. When it comes to stuff I know, most of the time the diagnosis is made by making a snap judgment about the patient as I walk through the door and then adding the first couple minutes (often less) of history. It really becomes almost intuitive and is the exact opposite of algorithms. Most importantly, you know when your spidey sense goes off that something isn't fitting quite right.
