Yea this is economics, not tech.

We also don't build carriages as well or have an army of craftsman doing it, but it's lost/regressed because there's no economic incentives.

We build car/truck bodies, which are much the same --- the family station wagon when I was growing up had a badge in the doorwell, "Body by Fisher" w/ an image of a carriage, that company having been a carriage-maker which transitioned to car/truck manufacture.
