As someone in his 30s who's never really been a fan of western pop culture, let alone eastern pop culture, what's with the idol thing and its' prevalence in the vTuber sphere? Even when it comes to japanese music I tend more toward jRock and bands of various genres(metal, hardcore punk, goth) that just so happen to be Japanese and find the whole idol thing baffling. Can someone explain this to my autismo brain?
