"Medicine training is time-based, but in flying it's competency-based. You can't move on until you're competent in that field."
So basically this guy, WHO TRAINS SURGEONS has only just discovered that it might be a good idea if
a) They can do their job

and
b) Their bosses had a system in place to check if they can do the job
As I've long suspected with the medical profession, competency has nothing to do with it. As long as you've done it for a long time, whether you doing it right or wrong, they will promote you to Doctor or even, evidently, Surgeon!!
Competency, ability and checking they're any good is, or at least up to now has been, irrelevant - Anybody else scared?
