I think people overestimate medicine as a field. It is incredibly slow and conservative--sometimes out of fear of ethics, more often out of rather poor incentives and scientific practices. Data falls on the floor with every patient. Medical training requires calculus *useless and ignores statistics and probability. It is still a rare medical school that teaches anything about AI or patient data systems. Hospitals swim in bacteria. I have personally witnessed data handling that would shock a good undergraduate-trained data scientist. On and on it goes. I seriously doubt progress in this field will arise soon.
