I agree a little bit, but I think you're swinging the pendulum a little far the other way. I work in a highly regulated area with consequences similar to "bridges falling down", and guess what? At an individual level, everyone is still winging it. What we do have though is a lot of processes: mandated things like checklists, written down procedures, standards that we work to and second-checking by peer or senior colleagues. It's those that stop the "bridges falling down", but at a personal / career level - people are all still exhibiting those people-like behaviors - rushing their work, making all kinds of mistakes, big-noting themselves, saying stupid things, etc. We design processes that kind of concede that "everyone is winging it all the time", so that things still be ok anyway.
