I lived it as an engineer. Started on the drafting board then moved to 2D cad, then 3D cad and then to solid modeling. ProEngineer and SolidWorks. I followed the space program starting as a kid. Most of the hardware used to get to the moon was the modern equivalent of one off prototypes. Machined on manual mills and lathes or at best numerical controlled machines using punch cards. People nowadays don’t have a clue how it was then. Rotary dial phones! It was the sixty’s.
