Ch1: Bridges, dams, etc are “charismatic megastructures” like “charismatic megafauna”. Infra easy to ignore, but is a critical hyperobject. Large public infra done for efficiency. Infra = networks, connects people:people & people:place. Creates path dependency for future. Rooted in past: tells the story of society. Need to recognize injustice. Infra shows us at our best as we try to take care of one another.
