Can't say we weren't warned about this threat back in 1995, In their book:

War and Anti-War: Making Sense of Today's Global Chaos by Alvin Toffler,Heidi Toffler, they described the link between technology and modes of warfare. Beginning with a provocative analysis of warfare in the past, futurists Alvin and Heidi Toffler give an eye-opening portrait of the tactics of the future. They exposed the horrifying realities of future wars in which Information becomes the weapon of choice. They also offered innovative and feasible strategies for implementing future peace. But we were too engaged in gaming and our addiction to technology to pay attention. So today it is John Deere tractors, tomorrow it may be Nuclear Reactors, Autonomous Vehicles, and Rogue Drones.
