Could civilization actually end like this? Not in a big bang but slowly grinding to a halt because no one knows how stuff works besides some nonfunctional web forms? No. I'll give you a clear counter-example: my iPhone 13 mini. Go read an iFixit teardown of any advanced product like that. Many state-of-the art chips, many suppliers, a huge logistics effort. And yet Verizon managed to send me one of the damn things just a few days after I ordered, shortly after the phones were introduced. Sure, some people trying to fund their product using kickstarter have problems, but the big boys can build and deliver hundreds of millions of "supercomputers" per year.
