Write a discussion board response to the claim that we should have more courses that are focused on technological issues that are presented in shows like Black Mirror.
You can agree, disagree, offer suggestions for the course--or address the claim in any way you see fit. It's extra credit, so just write something interesting and you can get the points. And there's no need to respond to other students--unless you want to.
To do this writing you don't need to have seen Black Mirror, but if you have watched it, say something about an episode or episodes that spoke to you.
Or if you know of a better written or visual text that comments on the topic, mention it.
