@dysfun Not videos, but yes. Same with the introduction of checklists and processes in operating rooms.
In *every* industry some people notice some mistakes happen over and over again, pushes to introduce checklists with the expectation of improvement, cowboys complain loudly about being baby sitted*, and if the checklists still end up being used despite the loud complainers the clearly measured result is "these work, who would have thought".

* hell, reading about the whole collective "You want *me*, a *surgeon* to wash my hands!? You're calling me filthy!?" and fallout has made me drastically change how I approach proposed changes.
