"Earth has never in its history had to contend with 8 billion fire apes, intelligent enough to have leveraged power by exploiting and burning one-time resources. We now operate outside the bounds and protections of evolution: in breach of contract, without a map to success. What could possibly convince us that this fireworks show—which has not even come close to standing the test of time—can maintain anything like its current resource impact for the long haul? Humans have demonstrated convincingly that we can live in a primitive state for hundreds of thousands of years. Our present mode is a few-century flash, supported almost entirely by inheritance-spending. Arguing that we have found a new normal is a precarious position that I would not be eager to defend. Parties end. Fireworks shows end. Why would our flash be any different? It’s not just guesswork: what other outcome could result from rapid resource exploitation on a finite planet?"
