I see that the compilation and distribution of "civilisational reboot manuals" is already on the list. I love the concept, but think this scope should be significantly expanded to include stress testing and refinement of the drafted content. This would verify whether the most important facets of knowledge and technology are covered, and if the detail and style are such that they can be followed. I heard this suggested by Lewis Dartnell (author of "The Knowledge") on the 80,000hrs podcast, and think it would be great to really run with it. A fun, high-profile and potentially profitable way would be through a televised competition format, where teams of "survivors" have to try rebuild as much of the tech tree as possible (or reach a set technological achievement), with a "civilisational reboot manual" as their guide.The mechanics of such a competition would need thoughtful planning to get a working balance between being sufficiently realistic of civilisational collapse scenarios (number of people, resources on hand etc.), have an acceleration mechanism to model decades of rebuilding within a season length, and be watchable. Challenging, but I don't think it would be a show-stopper (terrible pun, sorry). Benefits of this could include:
An incubator team could refine the concept and goals, perhaps do some limited trials, and then pitch to various networks or streaming services.
