Well, I meant more like basic industrial and scientific knowledge, e.g., that petroleum can be used as a fuel, or that the universe is quite large and the Earth revolves around the Sun. Even if 99% of the world's civilizations were erased and you had a zombie/nuclear/etc. hellscape, I don't see people losing this basic sort of knowledge. It's simply too pervasive. The idea of humanity returning to a caveman-level of knowledge seems unlikely to me.

Agreed!
