So I googled and didn't find a related topic in such terms. Suppose we put a few astronauts on an asteroid, no regular contact with Earth. The moment they detect the light on Earth has blinked out, they send a projectile of Gray Goo to the Earth to stop the AGI from completing whatever its assigned end goal. If MAD has kept us humans in check, surely it'd work on more rational agents?
To give you an overly specific answer, presumably the AGI could realize the existence of the trigger and just keep the lights on while surrounding them with with paperclips?
