I see your point and agree - if you look at ML and computing in general as a tool useful within the current context of medicine.
But I think the whole field of medicine (or a big part of it) may become obsolete - because the change will be driven by technology, not medicine.
By monitoring people's vitals in real time - think wrist bands which can do blood tests (+ urine, sweat, sperm, etc), feed that real time data to ML algorithms, train it on billions of people and you can accurately tell ahead of time when a person is getting sick. Next day the drone brings the medicine.
Doctors will still be involved of course, but their role will be mostly to confirm whatever the algorithm has decided..
So I think we'll be seeing a move to preventive medicine / real-time monitoring during the next decade or so and within our lifetime people might not be involved in medicine at all.
That is, if we have peace and things go according to plan... Which is a long bet of course.
