I think (?) my point was that Socrates equated Memory with Wisdom, and the invention of writing would impact Memory and thus Wisdom. I believe he was just plain wrong. Equating (manual) coding/code-review with Wisdom makes the same category error.
The passage criticizing the "invention of writing" is a quote from a legend where a Pharaoh passes negative judgement to a god, by the way, who had invented writing in the story.
Ironically, the dialogue in question, Phaedrus, is about the dangers of misreading text. It discusses writing political speeches not writing per se.
