The more I talk to people in my life (friends, family, mentors, teachers, etc) the more this story seems to repeat itself. People who have a somewhat uncommon issue, and are forced to go from doctor to doctor until one finally recognizes the problem and knows what to do.
I think that we have a couple problems. One is that we just don't have enough doctors to give thorough care to each person. They're under too much time crunch to really investigate. The second is that the human body is hopelessly complex and I'm not sure humans will ever be able to be good at diagnosing problems with it effectively.
Until we develop real gAI and much better imaging techniques, I'm not sure we will ever solve this problem in a satisfactory way.
