Most people probably only need a yearly-visit to the physician's assistant or a nurse for bloodworks. There shouldn't be a need to see an actual doctor on a regular basis (unless you have some chronic ailment that nurses / physician assistants can't handle).

The prescription is probably the only part of that routine that requires a doctor.
50% of doctors graduate in the lower half of their class each year. Lots of low hanging fruit with ML if implemented properly (big if, I know).
Unfortunately, that is of very little use to the clinician. The big hype is a consequence of a big misunderstanding of the practical constraints of healthcare.
Time and effort don't fix bad data and bad statisticians.
Like, if there is a problem with their performance, it is a problem that they are graduating. And then look at the group that is admitted. It isn't a low bar.
How much of an average doctor's day is really appointments like this where they just check you lab values and ask you if you're doing okay on your medication and send you on your way? A large number of these cases are already handled by nurse practitioners and PAs. Doctors in my experience spend more time seeing the sicker patients with many chronic medical conditions where the more in depth knowledge of pathology and pharmacology that they spend those years of training acquiring inform the questions they ask, the tests the order, and the physical exam they preform.
I don't think the large majority of PAs and NPs really want to step into the same role as physicians. The number of PAs and NPs who were rejected from medical school and then chose to take either of those routes is probably very small compared to the number who chose to become a PA or NP because they wanted that role and not a doctor's.
This is not about replacing people wholesale, but giving them better tools.
Nobody here is against that.
It's really a political problem.
People don't seem to have enough motivation to politically fight to replace doctors with nurses, and doctors have a lot of power and motivation to keep their jobs.
And what about powerful actors from inside the system ? Hospitals, Insurers, etc ? In general, everyone gets a share of revenue. So why bother reducing that ?
physicians usually hit their stride 5-10 years before they kick the bucket.
