“In the premodern world, control reached to points and the lines connecting them; there simply was not enough prevention of motion to go around to cover an entire plane and bring it all under control. In the modern world, this changed, and the topology was inverted: control reached everywhere, and only isolated points were left for motion, that is, not controlled from a center.” – Reviel Netz, Barbed Wire
