I think that it's hilarious (in a grim way) that we got this thing : a 30kg robot with no proven reliability performing dynamic/active balancing at all times and everyone jumps to the fear of 'The Scary Foreigner' rather than the fact that this actively power-damp'd mass is actively trying to fall backwards or forwards, being held together by whatever control loop, onto your toddler or pet.
A single non-redundant power-failure is orders of a scarier proposition to me than a foreigner with a bad attitude : you can fix that with management and action auditing , more than a single person in the loop, etc. You can't fix the future awaiting technical failure.
We still haven't fixed bad technicals in any industry yet -- we occasional get bad planes delivered to customers. We have technical failures in pacemakers.
