I think those are good points, but very few health conditions lend themselves to a smart chatbot replacing a doctor. Things like preventative care would be much improved by AI, but that is not protected by licensing. So why hasn't it become more common? Largely because people don't really care about it. Health is viewed as being binary, and our system is geared to address severe trauma (via the ER) and routine surgeries (hip replacements, coronary bypass operations, etc.). Primary care is improving, but in our current landscape it's a gateway to the more scarce resources of specialists. Most people who see a primary care doctor regularly are far from healthy and the doctor deals with managing multiple complex disease processes and specialists. Yes, you could replace the primary care doc for a patient with ongoing heart disease, kidney disease, and mobility issues with an algorithm, but that's not the hard part.
