In this week’s “Today I Learned” Polygon’s Editor at Large Chris Plante tackles what it is to be a pop star, the existential crisis many real idols face during the end of their limelight, Justin Beiber’s recent public breakdown and how this all compares to ‘virtual idols’ such as Hatsune Miku. It examines what it means to be a star, how these stars interact with the public at large, and answers the question “Is a Virtual Popstar Better than a Human Popstar” using Hatsune Miku vs Justin Beiber as proxies for the argument.
