As long as people want the benefits of technology/electronics in their medical care, the system will not likely change. The more technology is involved in medicine, the more specialization there will be. One day during an average outpatient surgery, I counted at least 14 machines in my room that I need to know how to operate and troubleshoot - and that was only for that type of surgery. Every specialty has its own complicated equipment.
When I'm having surgery, I'm glad my anesthesiologist is a specialist, I'm glad my surgeon is a specialist (as opposed to a general practitioner), I'm glad the surgical assistant is specially trained. I'm glad heart nurses know what they're doing during cardiac surgery. I'm glad I have an insulin pump and sensor and that my MD specializes in diabetology. We all benefit greatly by specialization.
GPs are just what the name implies. They have knowledge in tons of areas, but specialize in none. In medicine, an individual could get advanced degrees and be a genius, but they will be at their best when they thoroughly understand and can function in a specialty. Oh, and then there's the fact that we are learning constantly because of how technology changes and improves on a daily basis.
It is unfortunate in many ways, but also you and I benefit from all the technology available to us.
