The history of factory automation and mass production goes back long before the development of electronic digital computers. For example, quoting from http://en.wikipedia.org/wiki/Mass_production#History:
Crossbows made of bronze were mass-produced in China during the Warring States Period [in approximately 475 BC]. The Qin Emperor unified China at least in part by equipping large armies with these weapons, which were equipped with a sophisticated trigger mechanism made of interchangeable parts. Ships of war were mass-produced at a moderate cost by the Carthaginians in their excellent harbors, allowing them to efficiently maintain their control of the Mediterranean [in approximately 264 to 146 BC].… Mass production in the publishing industry has been commonplace since the Gutenberg Bible was published using a printing press in the mid-15th century.
