Imagine an AI run war.
The AI runs a war simulation and determines the winner in seconds without any actual fighting.
AI drones and robots could mean an increase in warfare for resources and more humans dying (just not from the more tech advanced country). The main push back against war is all the body bags coming back home (ieg. Vietnam, Iraq) Its hard for a Government and its media to cover up when families are losing their sons and there are homless Vets with PTSD.
If its just a robot and drone army used to invade, kill and being blown up in some far off land, your average joe NPC citizen wouldn't even know.
