Is the person who presses a button that releases an autonomous kill-no-kill drone into a country going to jail when that drone razes an entire town of civilians? I doubt it. “Mistakes happen” etc.
The visceral reaction is not there that would motivate the legal system to send the group that started a cascade of autonomous decisions by a robot to kill a bunch of civilians.
That depends on those two imaginary countries. Also, are you unaware of the many instances where people faced no accountability even when it wasn't a mistake, but deliberate?
