I very much believe in swiss cheese safety systems. There *will* be errors, you try to avoid them becoming catastrophes.

And I hate systems that don't let you say "ignore *this* warning" without turning off all warnings. I have some Tile trackers with dead batteries--but there's no way I can tell the app to ignore *that* dead battery yet tell me about any new ones that are growing weak. (We haven't been using our luggage, why should I replace the batteries until such day as the bags are going to leave the house again?)
