You know, Vocaloid has been one of the reason that the future will become focused on developing an artifical idol. The motivation for this is artificial idol can be perfect and adapt to many different song genre. Besides that, monetary reason might be one of the primary reason. Artifical idol can’t be sick, won’t complain, and strive to be perfect. The fusion of that notion then is completed with HRP-4C, a humanoid robot who has to the ability to mimic singing and the expression it should make while singing. I’m experiencing a Chobits flashback when I saw this video. When it happen, I’m sure our PC will be replaced by Personal Robot (PR). Your thought, guys?
