***An Economist Best Book of 2021***

Artificial Intelligence is going to war. Intelligent military systems are already reshaping conflict — from the chaos of battle, with pilotless drones and robot tanks, to the headquarters far from the action, where generals and politicians use technology to weigh up what to do. AI changes how we fight, and even how likely it is that we will.

Warbots will be faster, more agile and more deadly than today’s crewed weapons. New tactics are already emerging, but much deeper thinking is needed. When will an intelligent machine escalate, and how might you deter it? Can robots predict the future? And what happens to the ‘art of war’ as machines become creative?

An international campaign against ‘killer robots’ hopes to ban AI from conflict. But the genie is out — autonomous weapons are too useful for states to outlaw. Still, crafting sensible rules for our warbots is possible. This fascinating book shows how it might be done.
