first of all, human music is better. miku is just ai. in fact, without music, miku wouldn't exist. or at least not have a purpose. and before you say "oH WelL MiKU iS aCTUalLy a VOcalOiD aNd nOT ai", YOU'RE WRONG! Miku was programmed, first of all, and holograms are considered "non-existent things shown in real life using projector tricks", but "non-existent" can be AI, probably making her one of the first AI. second of all, miku is usually known as "a singer", but can also be seen as an anime character to people (she's literally japanese) and I do NOT like anime. (unless it comes to avatar the last airbender, then we're fine). third of all, her appearance. first of all, if rapunzel gets replaced in the future then it would be by her (which i would hate.), and second of all, she looks like an anime girl, which is seen in pretty much every japanese anime, which some people see as "cute" while others, such as me, can see it as "cringe". Lastly, her voice. Why does everyone think siri if she was drunk and japanese sound good? is that enough explaining to shut your mouth gng
