Thank you. I wondered what company that was.
The line workers seem well trained and perhaps they make their job look easy. Of course if you work with your hands while others are watching, as I often do, it's fun to make it look easy. That being said, look at the intersection between man and machine here in 1936. They already had four hands in a press requires four buttons pushed before the damned thing comes down.
It's probably fun also to show off the robots which the Tesla video did.
Closest I ever got to a monster assembly line like these was helping a plant layout guy from England working on a Jaguar plant. I was just the Autocad guy. He had a funny way of saying Jaguar, something like Jiggy-wire. Cracked me up.
