But they still have the concept of one very highly skilled and expensive doctor in front of every patient. It is a form of craft industry. It hasn't moved on to the industrial area, where you only need very skilled workers to create and prototype, but that scale well by not putting these expensive workers in front of every customer. Even banks have done that.

I am not saying it is easy, and perhaps the technology doesn't allow it yet, but undoubtfully this is a next step in the medical profession.
