It’s just not something you can do in your garage these days (or for the past few decades), even if the designs were open sourced. I like your idea and wish there was less concentrated power in chip manufacturing, I just don’t think it’s very feasible.
I work nights with 2 other guys. One of them is cool and seems to be a bit introverted, but we’re both into sports so we’ll watch games the first few hours and chat intermittently. The other guy openly hates sports, but loves “shooting the shit”, which he understands to mean him going on a fringe political rant or into way too much detail over some random shit he saw on YouTube… Luckily work gave us headsets with ANC, so me and the cool guy just headset up once the games are over and live in silence on the slow nights
