Just got an error trying to view that video, but if it's Discovery Channel's position that they're "machine made" just because a lathe was used, that would be typical of that channel's reasoning. I've found that channel to be in general of the poorest sources for anything sensible, much less factual - what they call "science" is at least as often not, and also its cousin History Channel is hysterically unhistorical.
The use of electricty is still a fairly recent addition to human culture, and the most amazing work done with all materials was done before that. So, if the use of electricity is cited as an issue with the claim "hand-maid", then do you think they all used only simple knives before such power came into use? They still could have used this gadget known as the mechanical, gear-driven crank, and with another on hand to operate that they could get a lot of things done.
