Sensors detecting someone in the seat is still more complexity prone to unexpected failures. Most seem like they would be harmless, but then there's one that floods a sensor bus, etc.
I would want to understand why a pilots resistance to the motion was not enough, how could it be made less capable at winning that battle and fall into its normal back off?

I think such an airplane has this sensor to the extent that it is a modern misdesign roped in by the ease of adding unnecessary parts.
Who has tested the plane with no detectable pilots in real flight, how often will these sensors be in the percentage of unnecessary parts in defect.
Now that people are thinking this way did they forget that a good seat adjuster can't be overbuilt to destroy or kill whatever is in front of it when it is allowed to operate?
Self recovering fuses are cheaper than ever and are all that's needed if no one has upgraded parts based on higher is better instead of designing to use.

Sure, I agree with you, but you might want to consider that an indication if a seat is filled might be useful for other things as well — in the end there has to be a total calculation that factors the reliability of any given part (and rhe humans using it) in.
> The Wall Street Journal reported late Thursday that a flight attendant serving a meal in the cockpit hit a switch on the back of a seat that pushed the pilot into controls on the 787, pushing down the nose of the plane. The newspaper cited anonymous U.S. industry officials who were briefed on preliminary findings from the investigation.
This sounds a lot like a design issue. If the button is on the back of the seat it is probably not meant to be operated with a pilot in the seat, yet it could be (accidentally) operated with a pilot in the seat.
We don't know the details, but any switch pointing to areas people move in should have a switch guard on especially when pressing it can lead to 50 hurt people. But in this case I'd propose the switch should either be at a totally different position or not activate if there is someone in the seat.
