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?

I think it's crazy to not open source everything, which is would happen in communism. Not just because of bus factor, but also for collaboration. Companies put random trace metals in their experimental chips, so you can't reverse engineer them from mass spectroscopy.

On the other hand, a lot of the knowledge isn't really secret, just patented and documented in papers. And many, many research institutes and companies who don't even make semiconductors, just parts for machines who do, share in the knowledge. After a catastrophe, we wouldn't have the newest generation chips anymore and it would take a lot of resources and effort to rebuild fabs, but we wouldn't start from zero.
