Yeah, the medical training model fosters a culture of working ridiculously long hours and shunning those that don't. As a first year surgical resident it's not uncommon to work 110-hour weeks and anything less than 80 feels like a joke.
And, as other posters have pointed out, this is despite legislation limiting the number of work hours. The fact of the matter is that if you were to actually work to the letter of the law you'd be sneered at, receive poor evaluations, and patients would suffer because there'd be no one around to do the work.
Most programs argue that these hours are necessary to train surgeons since there's not only the usual cognitive side of medicine, but also the technical side of cutting, sewing, etc. That being said, 70% of the hours I put in at the hospital are BS "scut" work which could be automated, streamlined, or passed off to assistants. The actual challenging decision points are few and far between.
Thus, even the 10,000 hour rule--which a lot of programs use to defend their dismal hours--misses the mark completely since, well, the practice isn't focused.
I don't think surgeons are going to be replaced by robots in a significant way for some time, but I would like to see the hands-on part of surgery being performed by techs. A three year, well planned course would be plenty to turn you into a competent operator--as competent as many just-licensed MDs. After all, do you really need 10 years of academic training (four year undergrad, fours of medical school, two years of little operating as a junior resident) to screw bones back together? Why should we expect surgeons to be technically AND intellectually gifted?
