The strangeness of materials, how molecules get moved around and re-stirred and stuck with other molecules to make new things that have new jobs that take up space and perform certain duties. Paper is trees and glass is sand and a human hair is stronger than steel but buildings are not made out of hair beams. After it happens, things will be made out of chance, out of cast-offs, out of things once intended for other uses. Maybe other organisms will follow suit. I’ve seen nests with candy wrappers. Birds with plastic in their bellies.
