The amount of data we processed with pen and pencil was multiple orders of magnitude smaller than what we do in 2023. We might be able to maintain a few systems chugging along with pen and paper but just imagine the sheer magnitude of all industrial control systems that rely on automation, every single one of those won't exist. Processing 2023 taxes manually, that's another hell by itself. We will regress much further than the 1940s, we don't have living knowledge of how to keep complex systems working that way, we will need to relearn all of that while in the midst of absolute chaos. The main issue won't be technical but social, when civilisation is collapsing it's pretty hard to maintain order to bootstrap these complex systems with pen and paper...
