I love sci-fi and it’s very tempting to jump in feet first to discuss the growth-is-forever-possible-if-we-live-in-the-matrix argument from Noah Smith’s latest piece The Metaverse and (near-)infinite economic growth. But I won’t do that now. Instead, I want to respond to the – less amusing and yet extremely important – twofold claim that (a) growth is currently becoming green in high-income countries (it is not), and (b) that the degrowth argument is not theoretically founded (it is).
