Black Mirror: 6 Best & 6 Worst Inventions
2. BEST - Child Tracking
If you're a parent then you know two terrifyingly connected things;
1) Children seemingly have access to the speed force, and are able to move incredibly fast the moment you take your eyes off them. Seriously, kids are like Weeping Angels when you blink.
2) The fear of losing a child is one of the worst ever. Even the thought of it can leave you feeling sick to your stomach.
That's why Arkangel's opening sequence, in which three-year-old Sara goes missing, is so harrowing. And it's so understandable that her mother signs her up to trial the Arkangel system. This system is at the very basic level a GPS location system for children, showing where they are on a map. But this is just the basic level.
Parents can also monitor their child's vitals, seeing if they're getting the right kinds of nutrition from their food, and heading off any serious problems long before they become an issue.
The system also includes an optional filter that censors both the sound and visual representation of whatever stresses the child out. So, if your drunken neighbour is out on the lawn waving his bits around, you (and he) are covered.
What parent wouldn't want that?
