I agree that doctors quite often get things wrong and they also prescribe in cases where they should not.
You will still need that human element though IMO when it comes to someone's health. I think the doctors role will evolve to be more of a "health advisor" while also performing small procedures such as sutchering, burning off warts etc. As it is, many doctors simply try to match up your symptoms with those listed in a medical handbook.........it is too subjective, reliant on experience and simply not good enough! The diagnosis of conditions will gradually become the responsibility of new technologies and the sooner the better
