@namelus, No need for auto mechanics when all the cars are rusted out, stripped heaps. Same for most all other modern skills. By the time stuff like that becomes important it’ll be done a whole different way, generations after the collapse.
I’m talking the skills needed for being an asset to a self-sufficient community, and the multi-generational tools that go with them. Think panel saw as opposed to circular saw. Basic chemistry for black powder, matches, etc. Bee keeping and candle making. Spinning cotton and wool. Making wicks and thread. Hand hewn wood and the ability to convert it into structures, furniture, carts and wagons. How to make a compass needle, or a sewing needle. Stuff like that.
That’s what we need to pass on.
I don’t think we’re going to lose the ability to speak a common language.
