Smoke detectors are resilient little objects. It’s the one device I need
that has never done anything for me, except annoy. Your selfish will to
survive is so great, that when running out of battery life, you
abandon your smoke post and choose to shriek every few minutes until
replaced. Now that I’ve reached my wits end and ripped you out of the
ceiling, torn out your still beating battery heart; somehow you still
chirp. Its conclusive, smoke detectors are the subtle beginnings of the Robot Apocalypse.
