   How did they make molds for like, engines back in the 1800s when engines require things to be so so perfect down to very very small measurements for the moving parts to work correctly? How about on aeroplanes, and how did they get the molds so perfect to begin with? How were machines able to machine other machines back before computers could set everything to the exact measurement?
   
   Trains, man TRAIINNNSS!
   
   this reminds me of a certain chapter of Atlas Shruggd

   It's all a clever lie. The veil has been pulled over your eyes... the machines have always been running things.
