The same is true pretty much everywhere else (cryptography, sport, electrical engineering, aeronautics, ..). There is no greater teacher than a head injury or an electrical fire, the question is whether OP's fear is warranted or whether it should be encouraged. Perhaps they should not set the bit rate on a video codec until completely understanding the fundamentals of that technology too? I'd suggest like in many similar areas, gatekeeping is a not insubstantial force
