US military plan to create huge autonomous drone swarms sparks concern

A new Pentagon project envisages automated, coordinated attacks by swarms of many types of drones that operate in the air, on the ground and in the water. The idea is raising concerns about whether human oversight of such a "swarm of swarms" would be possible. The Autonomous Multi-Domain Adaptive Swarms-of-Swarms (AMASS) is a project from US defence research agency DARPA.
