Good read. I've been reflecting recently on the idea of demand-side economic growth as something that happens across two variables: consumption and reproduction. Until very recently in history, only the reproduction variable ever moved the big number much at all. It could be that as each of our own energy needs continues to increase, especially as compute-hungry AI proliferates and personalized medicine extends lifespans, it becomes culturally more normal for populations to fall.

Though as others have pointed out, nothing about our society seems to be set up to accommodate that at all, which makes it terrifying.
