> Ancient technology was astoundingly precise (see the famous Antikythera mechanism).
Ancient technology was neither accurate nor precise. Making two specific things fit (e.g. THIS dowel pin in THAT hole in a brass plate) does not require precision in the actual sense of the word, you can achieve the goal by consistently small iterations (ex: grinding the dowel down until wanted fit is achieved).
Precision (all my threads are the same) and accuracy (and they fit with the thread from every other machine shop) are what made the industrial revolution. Ancient technology had neither of those.
