I'm well aware of exponential growth, and I'm not talking about energy efficiency. I'm talking about how economic growth is not fundamentally coupled with the material resources we consume. Like, for a long time, food production was pretty well coupled with population - if you figured out how to grow more food in your country, you'd increase its population but not its living standards. That got disconnected in the industrial revolution, and the link between your standard of living and energy consumption is increasingly getting disconnected today in modern economies.
