Consider just war. Current drones are revolutionary but are dependent on a radio communication link which can be jammed.
There’s a strong incentive to make a drone that can compete its mission autonomously if the comm link goes down. If the target is solidly on enemy territory that’s one thing but weapons like tanks and artillery and drones work best when they are closely integrated with each other and with infantry so such a system needs to be able to reliably distinguish enemy and friendly troops as well as civilians with all the moral questions that arise.
