Noah Smith: Left Wing Dystopias.

Noah suffers from "number blindness", possibly as a result of short-term thinking. Of course we need growth in our current economic system - but it is NOT SUSTAINABLE.!

Simple math.

1% economic growth over the next century to 2123 implies a 2.7x increase in production. This may require similarly large increases in energy use, resource extraction, and even population size unless we can reduce population size but maintain growth with productivity gains. A planet with 2.7x the the current requirements to sustain economic growth?

But wait, that is merely a century hence. Surely we want civiolization to last longer than that? What abount the same growth for teh next millennium to 3023?

Well that results in an economy nearly 21,000x larger. Obviously the Earth cannot support this. Neither can any of the rocky planets, so it would mean that in a millennium, almost all of the human population would be living in space, perhaps filling teh solar system with habotats in a Dyson swarm.

And then what?

A millennium only looks back as far as the Norman invasion of Britain in 1066. Not exactly a long time historically, yet we would have effectively put our human future in a dead end. maybe all that production can be maintained by robots in the solar system, but to what end?

If we want to maintain a liveable Earth, with a population that lives well but doesn't destroy our biosphere, we simply have to consider nogrowth and degrowth strategies at least as far as consumption is involved. Earth would be far better off with a much smaller poplulation, all living comfortable lives at a high standard of living, with the most destructive of resource extraction and manufacturing tightly controlled and possibly even off-planet.

Current growth is just not sustainable over the long term. It is the same issue as decarbomnizing our energy production. There are always excuses to maintain "business as usual" rather than really aggressively working towards that goal.
