Being able to learn motions from people and reproduce them while preserving their balance and reacting to external forces is still the "easy" part. That they're still trying to impress with acrobatics that no real working robot would ever need to do, shows that the development of the abilities they need to do actual useful work and make economic sense isn't as far along as their investors would like it to be.

That said, I'm sure we'll be seeing a pilot program where these will be doing "real" work soon, given how desperate investors are to will these into existence.
