This. There is a huge amount of safety evaluations, precautions, training and failsafes we have to go through just for using a Class 4 laser at work in a controlled environment, where the worst possible outcome is permanently blinding someone working with it.

For a machine with the potential to easily maim and kill, to be completely autonomously operated in a chaotic environment where it interacts not just with other computer controlled machines but also with humans, even children, I honestly hope that the amount of safety precautions required will grow very quickly.
