problem of today is not having enough knowledge, books, ... for storing that stuff or for generating more appropriate stuff to work with modern knowledge they did not had, but problem is not having workforce big enough to do this stuff AND live in current economic system on top of physical/planetwide system.
there is just too may people and only two things can solve that problem - A) what stalin, hitler, did [ graph in GIF https://www.hawaii.edu/powerkills/20TH_C_MORTACRACIES.GIF ] B) culture of not having 4 children and having need to live energy expensive life.
after hitler in west, reforms were made.
after lenin in east, stalinist came.
so without having everybody on board choosing B)... what is the answer? and you can not be peruan-style farmer when you have terrorists pumping oil from ground , building tanks, drones, paying people to burn buildings, cars, writing nonsense "red-pilling" people ...
USA was lucky not having wars, and not having war in USA was 99.999% because of geography - no land bridge. and 0.001% of "tyrrany" of state not allowing mass murder in rest of the world (yes redpill-ing oil here). but culture is changing, state no longer cares about that 0.001% (or atleast seem so ).
we do not care about transporting muck into our fields so we do not need to manufacture fertilizers. so yeah culture is not important but it is. he means culture as a "we do care about sitting next to your field and thinking about it [but that means not spending time programming healthcare system systems] and we do care about earth" [even without hippie drugs]
