The massive supply chain for transistors / chips is something I chew on as one of the big unsolved problems of localization of supply chains, something I think most communities (and nations) should be taking very seriously in the face of geopolitical and environmental destabilization. Plus it's better for your economy or whatever, I don't know, it just seems crazy to me that entire economies can collapse if one country decides to close its mines or another country decides to blockade the country where all the chips are made. There's always guys like this: https://simplifier.neocities.org/ https://simplifier.neocities.org/ whipping up stuff in their backyard, but so far as I know there's no serious alternatives for general computing that I could, with serious organization with, say, my entire city and the surrounding countryside (which includes some mines), use in case of global destabilization to start building our own computers. Tinfoil hat guy maybe but I think we should have that kind of backup plan ready. Just in case!
