I'm not an expert in this area so IDK. I could ask my brother if he knows if you really want? I imagine one of the differences is that they run 24x7x365 without any downtime unless it breaks (they never do maintenance only break/fix). These machines were super overbuilt so maybe they were never used at peak capacity back then either? Maybe there were improvements over the years? I assume the getting raw materials to the factory is much more efficient now days allowing more production then they used to be able to have? Look how many things ran out during the pandemic. Maybe we are over capacity at many of these places already? How often do any of us head out to the middle of nowhere to check the stock levels of product regularly?
