@soozyg- Well, i don't think it is fair to complain that an entertainment company made an entertainment product. that' slike saying, "There goes NASA again, sending another rocket into space."
That said, there is real value to this. Teaching robots to do complex autonomous activites is hard. Miniaturizing it is harder. Think about a situation like manufacturing. Manufatcuring is a very comlex dance of movements that machines have to be meticiulously programmed to do. If you could teach robots to naviagte that process without being quite as choreographed, they'd be safer and better at their jobs. I'm not saying Disney is getting into manufacturing, but these sorts of technology have a way of inspiring other areas.
