For a part of the program that I'm familiar with, a rotating fellow will be expected to be the sole physician of that specialty on-call for the entire weekend for 3 hospitals in a large US city. Then, on Monday it's back to work again at 6 AM. If it's a busy weekend, good luck getting more than 1-3 hours of a sleep a night during that time.
I'm so sorry about your dad.
The comparison is a good one, because we have figured out how to minimize the risks for fighter pilots, but doctors rebel when asked to adopt the same style of work.
Before taking off, all pilots - from Cessna to A360 - go through a pre-flight checklist. No pilot is expected to remember all the things that need to be checked - we know that we can't rely on memory. We tried this before, and people died.
Yet doctors only now are starting to adopt checklists, which are known to drastically reduce simple, avoidable deaths[1]. Things like rates of IV-induce infections go down to nearly zero when doctors stick to a checklist -- but many won't; the practice is met with skepticism even though it is known to work.
It took a long time for doctors to start washing their hands and stop killing people that way.
It's also pertinent to recall that surgeons evolved with and into the medical field from surgeon-barbers... yes, the people who give shaves and cut hair also used to cut into people.
That's horrific.
If that ends up being case then 'choosing a human' may quickly become a Market for Lemons situation - you might have gotten better outcomes from human surgeons except the only ones still doing it by hand are full of themselves and too proud to admit they are human and make mistakes.
Those I know do understand the effects of their working conditions. The "appalling and tragic" aspect is that we accept them until they affect us.
