For some viewers, the joy of watching on a streaming service like Netflix is that it does the difficult work of deciding what to watch for you. Powered by an algorithm, the service typically suggests TV shows and movies you can queue next based on your expressed preference and previous watches, saving you time and effort along the way. Convenient, right?
Sure. But on the other hand, there are just as many viewers who prefer making that decision all on their own, regardless of how time-consuming it can get. Renowned director Martin Scorsese famously denounced algorithm-based recommendations, claiming that "they take away from your creative viewing." A friend's good-natured suggestion can likewise be obsolete if we're just to trust the tech a hundred percent.
On a more simplistic level, an algorithm can also mess up your homepage once another person uses your account or you accidentally give a thumbs-up to a title you don't like; it can mistake others' actions for yours, offering you stuff you don't actually care for.
