The Ethics of Autonomous Weapons Systems in Just War Theory
Quick fact
A major concern is the 'accountability gap': when an autonomous weapon kills a civilian, it is unclear whether the programmer, the commander, or the machine itself is morally responsible. No one may be blameworthy, yet a wrongful death has occurred.
Why this is interesting
Imagine a drone that decides on its own whom to kill. Could such a weapon ever fight a 'just war'?
