>> Implying Miku Hatsune isn't performing at Anime Expo.

It's the experience. Sarah dislikes anime so of course she's against something like this.

Has nothing to do with it being anime. If my favourite band were going to put on a holographic show from a thousand miles away I wouldn't go to it, either, and would question those who chose to. Yes, live music is good (wasn't aware there would actually be any, thought it would all be synthesized via computer like the girl) but a major part of the concert experience is the excitement of being in the presence of the real person and perhaps even connecting with them for a moment.
