The problem is that it's impossible for anyone to reliably recognise when they're working beyond their competence, particularly in a field as complex and uncertain as medicine. A lot of serious and life-threatening diseases have subtle symptoms and are easily mistaken for more common diagnoses. The decision to refer someone for urgent tests often relies upon half-remembered trivia from medical school or long-honed clinical instincts. Replacing GPs with NPs will inevitably cause preventable deaths, the question is simply how many deaths we're willing to tolerate. That may be a perfectly reasonable tradeoff in health economics terms, but we have to be frank about it. I am hopeful that AI will go some way to bridging the gap between healthcare supply and demand, but at least in the short term we face a lot of difficult choices about how to allocate resources.
