The title is a bit over dramatic but, per the title, if you could contribute with one piece of knowledge to a book that every single individual should learn from in order to kickstart a civilization, what would be yours?
My personal choice would be the process of soap making, from scratch.
Basic logic gates for the most basic computational math As well as binary, octal, hexadecimal systems
I’m pretty sure you can make logic gates with water so maybe that’ll be of some use
Omg will they have redstone? :3
