Talking to the title for a second - (what they are actually doing seems quite different.)

This is funny, I think we might be underestimating the recalcitrance of human beings, and negentropic characteristics of life itself. (to say nothing of lawyers). After all there are still people operating the barriers at parking structures where I park in the morning, and they certainly cost more than a robot...

It seems that behind the recurrent question of automation and the anticipate crisis of salaried employment is a question of entropy and negentropy, not of autonomy and automaticity.

Law is distinctly negentropic and so is not the best candidate. Avoiding legal recourse would be a different matter ...
