Great comment! So many, at least from my reckoning online, seem to assume complex AI is just a given and we'll have it soon enough, but the reality is that these things are mostly puppets and the kinds of brains you need to come up with a clever song and dance on your own as opposed to having one carefully programmed into you is night and day. I think there's a reason we don't have mini, less capable, robots like these in our homes. We have the bodies, sorta, but we just don't have the brains.
Dancing just isn't impressive and like you say, seems a lot like a higher tech version of Disneyworld. What I want to see is one of these, on its own accord, run into a burning building and save a child. Choreography just isn't impressive outside of the 'wow' factor. Without advanced AI brains, these bodies are almost useless shells and I imagine Google getting out of this space may have had something to do with that.
