I think with the mindset about gaming being only for outcast or "losers" changing, it only makes sense that the platform is considered for other means of making money. Or making music. I remember when Gorillaz came out. It didn't bother me that they weren't "real" people in the music videos because the music was pretty dope. I don't see myself attending a concert with just holograms though like Hatsune Miku's.
