I feel like anything like that has to be predicated on not being able to find any book. Which is certainly possible, but I feel like $DISASTER will probably leave behind some libraries and books somewhere. The people would just have to be dedicated to learning the lost info from books + experimentation.

I worry that such an event would still be devastating. One fire was all it took to lose all of the wealth of Alexandria's knowledge several thousand years ago.
