I think the bigger issue is all the parts that we make currently for the production environment of cpus that use cpus in their production now. The cleanroom and robotic parts and such that would have to be made in old fashion ways and the whole process of finer and finer components that meet very specific tolerances and such. Like how advanced of parts can we make before we need vaccum tubes or such to make some machines to automate to a level to get an advanced enough part to make and integrated circuit.
Im talking precision of things like the screws in the hvac system. Manufacturing relies on other manufacturing that relies in the first manufacturing type of thing. So like how good a clean room can we cobble together to make how decent a cpu today. I certainly know the clean rooms of the past allowed in much to high a size particle to be used with our latest chips today.

This is about institutional memory. Like we know how to make a cassette tape player, but we can’t actually do it.
There are a half dozen people on YouTube today that literally made their own cassette encoding and decoding circuits for the Kansas City Standard.

Which is good enough to bootstrap 1990s grade computers.
Never underestimate the power librarians protect in their hallowed walls.
