A Smart Home That Lost Its Wiring

Imagine a smart home where the central control system (frontal lobes and limbic system) used to coordinate everything: the alarm system (amygdala) would detect danger, the memory system (hippocampus) would check if it's safe, the communication network (neurotransmitters like acetylcholine and serotonin) would carry signals between rooms, and the homeowner could call out 'I need help' in clear language. Now the dementia slowly dissolves the wiring—fewer and fewer signals get through because the messenger chemicals dry up and brain cells die. The house still feels things (a pipe is cold, the bathroom is overflowing, there's a fire outside), but because the wiring is broken, those signals cannot reach the control center or be converted into words. Instead, the house's only alarm left is to shake and scream — agitation, hallucinations, wandering — because it has no other way to tell you something is wrong. Add one more problem (a broken pipe that is flooding—infection, pain, constipation) and the already-damaged wiring becomes overloaded; the shaking and screaming gets much worse because now there is real danger and no way to report it. Fix the broken pipe, and even with the damaged wiring, the shaking often stops because the emergency signal was answered.
