Whether in the early cities of Cahokia in North America or Tiwanaku in South America, or the sprawling empires of Egypt, Rome and China, it was increasing inequality and concentrations of power that hollowed these Goliaths out before an external shock brought them crashing down. These collapses were written up as apocalyptic, but in truth they were usually a blessing for most of the population. Now we live in a single global Goliath. Growth obsessed, extractive institutions like the fossil fuel industry, big tech and military-industrial complexes rule our world and produce new ways of annihilating our species, from climate change to nuclear war. Our systems are now so fast, complex and interconnected that a future collapse will likely be global, swift and irreversible. All of us now face a choice: we must learn to democratically control Goliath, or the next collapse may be our last.
