The knowledge was not lost. It was embodied in a machine. What is lost is our connection to the materials and that is sad and profound.

In our A.I. robot future, we might be further from the manufacturing than our ancestors could have imagined.
Manufacturing Damascus steel was non-trivial.The knowledge domain has shifted, the people who made the steam engine would be lost trying to generate a STL file from G-code.
