I hear what you're saying.
The bot becomes the eyes and ears and adjust diagnosis and so forth. There's something similar already with key hole surgery. Definitely it'll benefit less invasive surgical procedures. But, these things still require an expert surgeon. When keyhole surgery is done by a novice they have better chances of getting it right with open surgery. Keyhole surgery thus isn't performed by interns and so forth. Only very experienced surgeons have consistent high success rates. Contrary to what some might think oh younger people are better with technology but evidence has shown far from the case with robotic surgery. Even though virtual reality and machine learning have been in health fields for decades, it hasn't accelerated better outcomes. Mortality rates and quality of life aren't that much better.
The more complex computing, the more specialised experts needed.
Not quite. I'm for completely eliminating humans in such matters, precisely because, as you delicately put it, they "will always fuck up regardless". And it can be done: getting and interpreting medical images is just a matter of good camera-work and pattern recognition (with some learning from past patterns). Surgery is little more than a skillful wielding of knives and needles-and-thread: butchers and tailors working on live meat. Nothing a good robot couldn't do.
That little progress has been made so far cannot all be attributed to the technology. Doctors are naturally not keen to support anything that might reduce their big bucks, and that gets translated into
impediments concerns in relation to "safety" .... laws and regulations aplenty.
Humans will always fuck up regardless. Trying to control for this is what autocratic regimes do. Cushioning these fuck ups is what the markets and insurance is for. Apparently it's still a mystery how leaving the market to just chaos and randomness just works..
There need not be an attempt at control. The selling line can be that people can save on insurance, invest their savings in the markets, and thus have more money and a more lavish lifestyle than the Joneses. There is no mystery as to how the markets work: They are basically all about finding suckers and skinning them. In that process, it sometimes helps to have produce and peddle something "useful"---a beneficial side-effect but not strictly necessary, as the likes of Madoff have routinely shown.
