I worked 8 years at a huge GM auto making complex.
This factory once had 12,000 employees worked 3 shifts + overtime.
When I was hired there were less than 2,000 employees.
More efficient machines doing more work, improved auto designs
using less parts, and ROBOTICS galore.
I used to watch these monsters in fascination.
They never stop, never get sick, never go on strike, never ask for
more of anything in anyway. They, like all machines, do break down.
When they do a specially and highly trained bunch of technician swarm
on the thing, diagnose the problem, fix it, and the line just keeps moving.
Two finished cars per minute flow off that final line!
