I’d hazard a guess that 8-bit machines played a part in the author’s young life - first computer, first job, happiest childhood summer, last computer they felt in control of before they got annoyingly complex - something like that. And therefore a collapse ending right when the author would have useful skills but things wouldn’t be too hard, is the most fun one to imagine.
Computing was around 40 years before the 1980s and electricity for a hundred years, but who wants to try and rebuild room sized punched card machines for ballistic trajectory calculations, get greasy fingers on mechanical parts, or deal with HT electrical power supplies safely, yawn, no fun there. rPi the same - by then everyone can do it and author isn’t special, so whatever. It’s not different enough from right now.
