But isn't it just the natural progression of innovations like interchangeable parts and assembly line manufacturing? And isn't it already a thing that we're progressing to with increased industrial output and reduced labour requirements? This is where we're going, we just need an driver to push us to do it. Space exploration and resource extraction from the asteroid belt/moon to prevent the complete destruction of our environment seems to be as good a driver as any.
