Algorithms: Friend of Foe of the Average Guy?

Thought some of you, if you have 15 minutes to spare (and it works well to listen while doing something else, the visuals don't add much; I folded laundry while listening/watching), might enjoy this video by Cathy O'Neil, author of Weapons of Math Destruction. She talks about algorithms and how they are used -- and how they hurt people, hurt a democracy.

Right around the 5 minute mark she discusses teacher accountability models, how they have accountability for the teachers, but there is no accountability for the model.
