I see this comparison a lot, and I think it's a trap, because it invites us to confuse scaling duplicates with scaling design changes.
Duplicative mass-production was always core to software from the moment it first became "soft". A factory churning out 10,000 copies of the same book maps to 10,000 downloads of a single software release. The paper and bindings of the book may be below hand-crafted standards, but the words are largely unaffected.
In contrast, LLM-coding is the design and prototyping stage. So if we want to learn from textiles/electronics, we shouldn't be thinking of acres of looms, but instead about fashion-design, custom tailoring, determining patterns for clothes, designing new appliances, choosing circuit layouts, etc.
"Does that code work?" "yes" "so lets ship it" "but its not good" "but it works right?"
This is just a hypothetical example, I'm not saying that this is how it would necessarily go in all cases.
