This is a fantastic video, extremely well done in my opinion. I remember fanatically watching "How It's Made", in that show they focused on more run of the mill assembly lines for generic plastic things and usually there was a ton of labor involved. The video linked here was really the first time I saw this level of automation and my jaw nearly hit the floor, the technology industry has created some incredible feats of engineering.
I watched How It's Made with my kids for a good number of years, and I was just amazed that the parts that were automated worked as well as they did. It made manufacturing look really complicated and that human hands were the most important part of the assembly line.
Very few high end factories would allow some random journalists to poke around. Some candle factory is a different story I suppose. But you are right,I'd love them to visit some more modern shops.
