plenty of earlier civilizations had better crafts than we do now.. Second, existing society has lost its crafts.. example 17th century French goldsmithing that is not reproducible today
I completely agree. A few hundred years ago is somewhat understandable. It’s the peak before electricity allowed further progression (and demise).
To me, 3k years ago is a bit more shocking, when I compare it with items from 5-10th century.
