As much as I'm worried about military autonomous drones, I'm even more worried about guerilla autonomous drones. With off the shelf AI becoming more and more accessible it's not too hard to imagine a moderately smart person being able to make autonomous killing drones using off the shelf materials. It doesn't even need to be autonomous. In the Ukraine war hobbyists have been able to help the war effort by Jerry rigging together bombs onto commercial drones. I'm grateful but shocked that there haven't been any major drone based terrorist attacks, and I'm not sure how they can be defended against.
