Killswitchable Robo-organs

[Roomba]

I don't like killswitching as a concept in general, I think it's dumb, makes rogue borgs/Ais too easy to counter, and can be too easily abused by a bad/short-tempered captain. I don't see why adding killswitching to more things would improve those things.

also, if the killswitchable organs were clearly distinct from regular ones, why would anyone go 'yes, please shove this heart that can be remotely blown up by a complete stranger into me'
