The uncontrollable rampage of the Nanomachine Swarm was one of the triggers that led to the collapse of the planet's civilization. The Nanomachine Swarm was indeed a taboo technology, but nothing stayed unchanged in that world. Something that triggered the war in the past had become the last lifeline for humans to depend on in the present. The global war had destroyed the original production system and pushed the planet's ecology to the verge of extinction. As more and more people became involved in the war, the agricultural and industrial models could no longer support humankind's survival needs. Hence, they restarted the Nanomachine Swarm. They made a series of better-than-nothing security improvements and made the Nanomachine Swarm the cornerstone of human survival. The Nanomachine Swarm provided food, air as well as medication, and it became the basis of industrialization. Ninety percent of the human beings in that world depended on the Nanomachine Swarm for survival.
