Good for this kid. It's important to nurture intelligence of this kind, even better at a young age. For those saying he doesn't have life experiences, I don't think its that big a deal. Sure there are qualities that will help you become better doctors, and if you have those experiences before entering medicine, great! However, I think in medical school you learn a lot, gain quite a bit of experience, and gain attitudes needed for the practice of medicine. I don't see why it would be any different for him, he's been around older people for a majority of his life, so why should medical school be any different. As far as I am concerned, he could be the next great scientist and I am not saying we should pressure him to seek after a self-fulfilling prophecy, however, it is important that intellect like this is not impeded.
I just have to say that is absolutely amazing and if I could, I would switch places with him. To have that kind of intelligence and passion to learn is very impressive.
