I know theres some crazy technology going on behind it, but it really just looks like animatronics moving to a recording, like one of those rides at disneyland. When it starts freestyle rapping about a subject spontaneously given to it by an audience member, then I'll be truly impressed.
And the dude talking about robots in the entertainment industry? Could you imagine paying to see a robot sing? It might be cool when it's new, but once the novelty factor wears off it would be like watching a jukebox play a song on a stage. The whole point of a live performance (at least to me) is that the music is being created basically from scratch, and theres always room for error and mistakes. I can't imagine a robot, no matter how complex or advanced, providing the same effect of a live performance given by someone who spent the better part of their life striving to perfect their craft. It would be like watching a computer animated magician perform tricks on a movie screen. It might look cool, but the magic isn't really there.
Maybe I'm being to harsh. I know they're just exploring possibilities, and I'm generally all about advances in technology, but this seems to be wankery.
