Black Mirror is a phenomenal science fiction/drama/thriller. You are right that we are creating the mechanism in our society that may kill us. We look for the outside forces that may lead to our demise, but the irony is that technological development opens the door for more and more ways to mark our own demise.
I recently wrote an article on one of my favorite episodes, San Junipero. It is basically about the real-life impacts of a virtual world such as the one illustrated. I think you might like it, and I would love to hear what you think!
