One reason is because medical and clinical training is tied to the outdated apprenticeship system. There is no Khan academy for medicine. Train doctors at scale like software engineers and this sort of problem will naturally go away. Decouple medical school admissions from residency.

The unfortunate state of things in the biomedical field is that without the magical M.D. title next to your name, you are not taken seriously as an subject domain expert.
