> It seems a fallacy to say that "machine learning" will replace the sensors needed to produce the data required to make a diagnosis.

I agree. Good thing I didn't say that :) My comment implied exactly what you wrote, that the machinery will get smaller, and machine learning will be able to make more accurate predictions from a more limited data set. Although, if we consider that the Apple Watch will be strapped to your wrist for 16 hours a day, it might actually turn out to be an expanded data set, but a smaller number of sources.

> I see this kind of confusion a lot, where "machine learning" is mistakenly used to mean obsoleting sensor data instead of obsoleting the hardcoded processing of said data.

I believe that's a misinterpretation on your part. I haven't seen anyone claim that machine learning doesn't require data from sensors.
