I have only 1 questions about the whole plot. Why did her husband connected her with household machines and installed monitor in every room? What was his purpose behind this? She is not an AI assistant who controls smart home. Her husband was not building one. He was transferring consciousness of her dying wife into an android. Ok got it. But why making that android responsible for opening and closing doors??
In smart homes, alexa like AI will follow your command. But here she is a human consciousness, there is no guarantee that she will follow your command.
So why on earth will you give her eyes and ears in every room?
