The sensor is not a cure for cancer, the recession, or unemployment. It would not benefit you if your crank snapped, your oil sump cover fell off, or if you hit a tree. But it does address most of the more common engine failure modes, all of which generate ferrous debris in significant quantities before the engine blows……..
And in the case of your friend’s car, it would have seen the bearing backing materials in the oil.
