Seems like there’s one or two multinational corporations at the bottom of the supply chain granting us the ability to manufacture semiconductors. Precision engineering that spits in the face of God. What’s the bus factor on the knowledge required to produce these? Companies forget how to make things they used to know how to make. It happens all the time. What happens when their institutional knowledge decays? We just can’t make the computers that run MRI machines anymore?

A hobbyist with a few thousands of dollars to throw around can make chips from the 70s or 80s in their garage. If some catastrophe wiped out all the best fabs, the machines that made them, and the people who knew how to put them together, as long as that didn't go along with a complete loss of all existing computing hardware and industrial capital you'd probably see production of chips from the 90s or early 2000s be up and running at scale within a year and as long as all the documentation of the actual tech behind modern chips wasn't lost people could relearn it and the machines required could be recreated and things would probably be back to where they are now within the decade.
