A pilot (let's assume flying at night, with cloud cover), finds themselves thinking their IAS and AOA sensors are whack and hits the cutoff switch for the auto trim, when in actuality the IAS and AOA were correct, and they are now approaching a stall instead of what they perceive to be the plane trying to nose itself into the ground.
While there didn't cutoff the sensors, this is basically what happened to AF447: there didn't trust the IAS indication anymore. This is why pilots have since more training to aviate with unreliable air speed.
From my point of view, actual redundancy practice in aircraft is obsolete and must be replaced by predictors that take in account all available information on the aircraft.
That's where defaulting to power/pitch control comes in. It's as close to VFR as you can get without looking out the window. It doesn't rely on any outside factors for information.
If you had a phone or a pad with a bubble level app on it, if you were careful, you could fly with that information and throttle position.
