Then how do you coordinate attacks? Even elite military units, deep behind enemy lines, have the ability to receive new intel. You aren't going to build a swarm of robotic generals, each fighting their own war, with no communication between them.
You're not going to launch these things with the order to "go fight the war" and hope to update them on the specifics later.
You're going to launch them with the latest intelligence on board manually uploaded, for missions less than 12 hours in duration. It's like firing a missile - you don't need to recall it once you've hit the red button.
So - AI 1 and 2 - drop 2x 500lb bombs on target at 6759 5974 at 03:12 hours. Go.
They complete the mission and head back. Even better, you give them 4x 500lb bombs and they figure out themselves how much to drop to destroy the target.
Communication worries are overblown, you just have to design around them.
What if you want to call the mission off? Let's say the enemy gets a few key hostages, and holds them in this building. They'll be killed by their own side.
Revokable weapons are weak; irrevocable weapons are strong. It's the same logic as mutually assured destruction, and evolutionarily similar to blind rage.
FWIW I believe autonomous weapons are inevitable because drones cannot be used against technologically sophisticated enemies that can jam them. The hard requirement for continuous communication is exactly what autonomy is eliminating.
The enemy didn't necessarily break the Geneva convention.
Pulling the trigger far in advance of the resultant action increases the risk of disaster, disaster that could've been averted based on the richer dataset available closer to the scheduled time.
They didn't have to. We're just going to say they did anyway because they are evil bastards (TM) and we can't possibly be anything but the good guys.
This scenario is the exact same scenario as a current ballistic missile launch. There are no safeguards for those systems that could be intercepted and interfere with the use of the weapon.
Send more drones to kill your own drones? If the drones can be fed new instructions in the field, then the enemy can feed them fake instructions to shut down.
