This article seems to try to ride the fears of AI and "bots are taking our jobs" but really this looks like plain old badly written software.
Large machines operating near people should always have failsafes. Having handlers who are expected to drag the bot around IMO isn't enough.
I saw a video of the Unitree [1] robot doing a kung fu routine the other day. I imagine developers are constantly programming in some pre-scripted moves. Similar to all the Boston Dynamics demo videos. They're great for showing off movement. Conceivable that someone could run the wrong demo routine. Imagine the Atlas robot doing it's classic backflip in the middle of a crowd.
IMO this means we won’t be comfortable with robuts and safety critical applications until they are well, well beyond human capabilities. This is where I think the crowd that aims for “human-level performance” is wrong; society won’t trust robuts until they are much, much better than humans.
But if you can’t tell if it’s “angry” then we have to assume it’s always unsafe. Of course this was always true.
