It is still unclear to me exactly what data they were looking at/referring to in this article. If you take into account bloodwork, family history, demographics, etc. then it seems like you are still only getting a few dozen data points. At this scale it seems like traditional statistics or human checks for abnormalities are going to be about as good. Although I personally know very little (apologies for conjecturing) it does seem like there could be a lot of uses for AI for specific diagnosis. For example, when they take your blood pressure/heartbeat they only get data for one particular moment where you are sitting in a controlled environment. I would think if you had a year's worth of data (along with activity data from an apple watch) you might be able to diagnose/predict things that traditional doctors/human analysis could not. I would also imagine anything that deals with image analyzing (like looking for tumors in scans) will be vastly better with computer AI systems than humans.
