Industrial society had to end. Why? Because industrialization is a lark, an experiment, it was never meant to last.
Industrialization was both the product and the cause of the largest scientific breakthrough in human history. It only started because of science and it happened to advance science. Now that human scientific output is ending industrialization will no longer be needed. Remember, all the "economic output" you see today was the product of science in some form. Once an industry matures and science can no longer produce any value corruption will start to take hold, companies will start to bake in other things to continue to produce profits, like subscriptions, hidden fees, price increases, etc. which don't add anything of value to the economy. Essentially at that point no more intrinsic value can be added to products, after this happens human birthrate plummets and manufacturing will no longer be needed. Nothing about the economy is "arbitrary" and 1st world birthrates are going down for a reason, same thing with the 3rd world. We've exhausted all the extensions science has afforded to us.
