What would happen if you had a closed loop of robotic arms controlling each other? That could cause problems with contradictory instructions racing from one arm to the next. They'd probably all get stuck moving back and forth a tiny bit.

Or, if you had the arm programmed for inverse kinematics so it would mimic the wiimote's actual motion and made a chain or loop then they'd move almost together, but with a little delay so that there would be a cool cascading effect.

"can carry on conversations, ... and answers questions with fact-based advice."

Sweet! Where can I get a dog like that?

"Or gates admits he's gay."

This possibility seems to be being overlooked; it would certainly go down in video game history and there isn't much else that would live up to their claim.

Wouldn't it be great to get (hopefully detacheable) extra limbs like this, not just replacements?
