ELI5: Explain Like I'm 5

Arkangel (Black Mirror)

Okay, so Arkangel is an episode from the TV show called Black Mirror. It is a story about a mommy who is worried about her little girl named Sara. She is so worried that something bad might happen to her so she gets a device called Arkangel implanted in her daughter's brain.

Arkangel is like a special tablet that only Sara's mommy can use. It lets her see what Sara is seeing all the time and even track her whereabouts. Whenever Sara is feeling sad or scared, her mommy can make it so that she cannot see or hear anything scary. This way, Sara can always feel safe and happy.

But as Sara grows older, her mommy realizes that Arkangel might not have been a good idea after all. Sara is becoming too dependent on it and doesn't know how to deal with her emotions. She can't even make her own decisions because her mommy is always there to make them for her.

So, the mommy decides to turn off Arkangel and let her daughter live a normal life without it. But this decision has consequences and Sara has to learn how to navigate the world on her own.

In short, Arkangel is a device that lets parents monitor their children's every move and protect them from harm, but it might not be a good idea in the long run because it can make children too dependent and unable to deal with life's challenges.
