9. Scientific advancement requires that in each generation, your culture acquires more knowledge about the world than it loses — and there are a lot of ways for a culture to lose knowledge; among them mortality, library fires, Alzheimer’s, censorship, tech bubbles, faddish beliefs or cults, pareidolia, political propaganda, shame, anti-epistemology, language change, revolt of the masses, economic collapse rendering high-tech/high-knowledge trades untenable, superstitiogenesis¹, the madness of crowds, and other noise. In the absence of really good schooling, literacy, anti-censorship memes, skepticism memes, and economic resilience, the noise is likely to dominate the signal, driving cultures back towards subsistence and ignorant superstition — a condition in which beliefs are no more correlated with reality than is needed to keep you alive from day to day. However, the difference is basically quantitative (how much is preserved?) rather than qualitative (some cultures Have It and others Don’t).
10. It’s just too hard to maintain the technology base for scientific advancement with 1% literacy; there’s just too much chance of losing it due to correlated death of the literate class — plagues; king decides to kill all the scribes and burn the books; barbarians invade and do the same; etc.
¹ any process by which new superstitions are created

I hoped the footnote would exemplify some such processes...
