>by an underpaid worker from the Philippines in their house (around their children)

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.

I cannot legally get a Philippine worker in my house at a price I could afford. Well I haven't checked on the exact immigration rules, but I don't have to bother to tell you that I can't get one that is enough underpaid that I could afford one. There evidence that elsewhere in the world people with similar wealth to mine have them, but they are not available in the US. I don't care who does the work so long as I can afford it and it is legal - which rules out slaves.

For purpose of this discussion I'm ignoring ethics (other than slaves and there I resorted to legal concerns to sidestep the issue) - If it was possible for me to get an affordable human in my house I would no longer be able to ignore those issues.
