Complexity is a great lens to consider almost every modern issue with, agreed. I'm also agreed with the money/power behind complexity. I'm not so sure I'd use the us vs. them framing. Most seem quite comfortable within modernity, even those who raise the rebel flag of their form of freedom or simplicity. I'm also not sure that those that monetize it (for instance, operating the most sophisticated supply chain end-to-end) think they are doing evil in return for money and power, they see it more as being efficient. We *generally* don't account well for energy, minerals, and negative externalities.
My take is that we arrived here in classic whack-a-mole of technology (we fix one thing, make it more efficient, and now we have three problems, etc.).
