It's unclear tech transfer is speech driven. People can read machines and reason about purpose without natural language. We've all learned tricks from undocumented code. I've learned mechanical tricks poking around scrap yards.
maybe unclear to you. may I recommend Orality and Literacy by Walter J. Ong. which talks about how text and writing transformed human culture
the point (which I learned from the book) is how writting transformed human culture but did not define it, humans have a pre-literal (i.e. written) culture whose origin is literally really lost to history
I'm saying that tech transfer can absolutely be speech driven, but I admit that text driven technological transfer is in some ways an improved version of oral-only cultural transmision (i.e. knowledge preservation)
Right, but there are certainly going to be a ceiling to how far one can go. With writing it can be copied nearly verbatim and kept for centuries whereas the human mind is brittle and forgets, fuzzes, and randomly changes knowledge, it can contain only so much data.
