"What's keeping us from using them?"
If you're "trained" to do something a better way, you'll take it for granted. Once whoever trained you is gone, you'll wonder why the next wave of new employees are relative deadweight even though you "figured out everything on your own." Once you have more than one weak link you'd have been better off doing things the mindless foolproof way, even if it means everyone has to work twice as hard to accomplish half as much. How much foresight are you using? It's going to be chaos after that
