> If you can't make CPUs and you can't keep the internet up, where are you going to get the equipment for enough "private peering or Sat links" for the privileged?
Storage. You only need a few hundred working systems to keep a backbone alive. Electron migration doesn’t kill transistors if they are off and in a closet.
> You need CPUs to build optical media drives! If you can't build CPUs you're not using optical media in 30 years.
You don’t need to make new drives; there are already millions of DVD/Bluray devices available. The small microcontrollers on optical drives are on wide node sizes, which also make them more resilient to degradation.
> they're definitely f-ing going to have been able to repeat all the R&D to build a 68k CPU in 30 years (and that's assuming you've destroy all the literature and mind-wiped everyone with any knowledge of semiconductor manufacturing).
If you read the post, the scenario clearly states “no further silicon designs ever get manufactured”. It’s a thought experiment, nothing more.

This kind of just breaks the thought experiment, because without the "why?" of this being vaguely answered, it makes no sense. How do you game out a thought experiment that starts with an assumption that humanity just randomly stops being humanity in this one particular way? What other weird assumptions are we meant to make?
If you don't like the rules of the game, you don't have to play it.
But, this is as if people said “well, I can’t carry the soccer ball in my hands, so I’ll carry it with my elbows instead.”

OK, no silicone. But we might be just fine after all. Just yesterday we had a story about Bismuth transistors that are better in every way than silicon ones. Maybe a tad more expensive. There are a plenty of other semiconductors out there too. We’ll have to adjust manufacturing but it will probably be just one upgrade cycle skip. Even with a complete mind wipe it’s still not that bad if only silicone is out.
