Not letting people (and much less children) around industrial robots is not virtue signalling, it's basic safety and common sense. Where's everyone's protective headgear anyways? What if it starts spinning around because of an error in the Gcode? This thing could kill everyone around it with one swing. Where's the emergency stop button?

Don't switch the topic. You were saying something about blaming the kid and suddenly you are discussing the safety issues.

Also, you haven't seen much chess robots, have you? "Industrial robot", my ass. Have you actually seen one? The one that "could kill everyone with one swing" is a tad different.

I think you're mistaking me with someone else.

Yep, I've seen and programmed many industrial robots. You would be surprised how easy it can be to kill a human with a swinging robotic arm, even a small one (such as the one here). Even a relatively light hit at the back of the head can be fatal.
