We are closer to creating our robot overlords

This demonstration video of a robot hand is amazing. It can do things like throw and catch objects and tie knots. It can even twirl a pen. Twirl a pen! I remember the pride of mastering that skill when I was just a nerd on the high school debate team. I was fine with computers beating us at chess, but not pen twirling. Is nothing sacred?

I'm half horrified that we're moved one step closer to creating the T1000, but also somewhat intrigued by the idea that the next gen Roomba will actually move about my apartment dusting and wiping. It's quite possible that before Arnold became a terrifying robot warrior, he was a useful, housekeeper.
