> I think it's actually the most likely future.

Well that deserves some actual argument. This abundant future has been promised to us for generations and has served as a justification for precisely fucking everything up in the name of the brighter future. Yet now we have, to my knowledge, no indicator of things getting better, but all indicators going way worse than we thought.

> I get being critical of mindless consumerism, but degrowth doesn't seem to be about "order less junk on amazon/temu"

Yes it is. It's about mindful production of useful products and services. Which is very much the same as reducing economic activity and energy consumption.
