I'm talking about technical documentation or videos, precise enough to replicate the steps and finished product, for things like:
- Agriculture - which seeds grow where, and how to start and care for them?
- Seed banks
- Mining at scale
- Geologic maps of mineral deposits
- Metallurgy
- Manufacturing processes
- Construction techniques. How do we build buildings today? Would we be able to replicate the supply chain so that people used to getting drywall, plumbing fixtures, and electrical outlets can actually get drywall, plumbing fixtures, and electrical outlets?
- Chemistry
- How to make and mold things like plastics
- Electrical infrastructure - how do you run and repair a grid?
- Modern medicine. Diagnoses, treatments, anatomy, etc.
- Semiconductor fabrication. It doesn't have to be the latest generation (which is insanely complicated), but any group that can get a ~2000s-era fab up and running while everybody else is struggling not to starve would have a huge quality of life advantage
- Other electronic manufacture
- Etc.
Sort of like the Doomsday Vault in Svalbard, but with the knowledge distributed across many communities, because Svalbard is likely to be the last place that people will be able to get to in a collapse of civilization.
