"Good luck ever convincing doctors (or the general public, legislators, etc.) to let themselves be replaced by machines."
This presumes doctors are in control, which they are not. I suspect the insurance industry will adopt and impose these technologies as an independent analysis channel in the same way they impose current bureaucratic process.
This is closer to reality than you might think. Doctors get less and less control in this as Healthcare costs continue to rise due to the aging population. Healthcare has to be come more efficient to be able to keep up or nobody would be able to pay for it anymore. So where we sold to doctors Five years back we now sell to hospital MT. Hospital MT controls the money and are constantly searching for ways to perform more cases a day. AI is their only viable option and so they will buy in sooner than later.

I do agree this will be a slow process.
