> Literacy surely makes accurate and trustworthy communication much faster.
This is an interesting discussion. My thought is that there are quite a few variables influencing when literacy/writing becomes an important technology:
a) durability and portability of media: most is either light and degrades easily or durable but heavy and harder to transport.
b) manufacturing cost: papyrus was used for millenia in the west but was never widespread because its production was time and labor intensive. Ink and dye would be another cost. Most stuff just wasn't worth the cost of writing down.
c) population size/density and network effects: small populations wouldn't benefit much because it would be more cost effective to trasmit and preserve information orally. Similarly, large but diffuse populations wouldn't benefit much because the cost of scribes and materials would be high relative to the population served. Given that writing is a "two-sided market" (needing both a trained writer and reader) then the value of writing is somewhat proportional to the size of the network of scribes. Given that scribes are expensive, it would take some time to bootstrap the network. It seems only large and dense populations would see an economy of scale for writing.
It seems like a number of factors have to line up before writing presents a favorable economy of scale for information transfer and preservation.
