We are currently living in the most abnormal time in human history. For better and for worse, the era we live in is unique in the annals of time. Never before have so many humans lived (7.7 billion, growing by 80 million a year), and the advances in science, technology and industry would have been considered miraculous only a few centuries ago.
Most of this progress began with the industrial revolution 250 years ago, and has been continuously accelerating ever since. The changes have been so profound that I believe the average person in 1760 would feel more at home in 2000 B.C than in 2000 A.D. After WWII, the “great acceleration” ushered in an age of unprecedented prosperity that spread from the west to the rest of the world. People observing the rate of change at the time and extrapolating forwards into the future naturally predicted that soon humanity would leave earth and expand to the stars. 2001: Space Odyssey is a good example of this idea.
Half a century later, this view of the future looks a lot less realistic. The world population growth rate peaked in 1968 and has been falling ever since, with no signs of stopping anytime soon. 23 countries have declining populations, and many more will join them in the coming decades. Excluding Africa, world population will peak sometime around 2050 and then slowly decline. Counter intuitively, this slowdown has taken place voluntarily, due to rising wealth and education across the globe.
On a different front, the growth of our man-made world has begun to bump into some hard global limits recently. Humans have modified the biosphere so extensively that some geologists have proposed a new geological era: The Anthropocene. We have caused the extinction of enough species to allow scientists to declare us responsible for the sixth mass extinction (The last mass extinction occurred 66 million years ago when a giant asteroid killed off the dinosaurs).
Our incessant burning of fossil fuels has destabilized the climate, and the IPCC’s warnings are becoming increasingly apocalyptic in tone. Respected scientists are now predicting “the irreversible collapse of industrial civilization” before the end of this century.
In light of these two seemingly unconnected issues, both of which seem set to halt the march of progress that has been going on since the renaissance, what might our future look like? I don’t take the apocalyptic “mad max” view championed by people like Guy Mcpherson (who predicts imminent human extinction) seriously, but the techno-utopian future seen in mainstream culture seems outdated by now.
What do you think? Are we inevitably headed for a kurzweillian-superhuman-techno-wonderland, in an unstoppable march of progress? Or will climate change bring down our civilization and begin a new dark age?
Personally, I like to imagine future generations centuries from now gazing in wonder at the ruins of our cities, marveling at the ancient people who constructed them. The idea of a trillion humans spreading exponentially through the galaxy has never appealed to me.
