So, let's say I want to justify an apocalypse where there are no assault rifles, fighter jets and heavy transport ships. I want to de-militarize the world a bit, so that overwhelming force can only be achieved in numbers and skill, not in tech.
What are the possible explanations for this?
Brainstorm with me?
1.) In Dune, there are personal force-fields that prevent motion above a certain speed. Bullets are rejected, but knives & fists pierce it as long as they are moving slow enough.
2.) The Psychic Maelstrom is expressed through metal. To touch metal is to enter its world. Fighter jets, train tracks, cars & guns are all puppets of the maelstrom. It can control them, but it rarely rarely does so - and when it does, it's to build huge geometric constructs of trash, and so on.
