It's not mentioned in the article, but as someone who's taken up remodeling my house as something of a hobby, it's always amazing to me to think about the amount of labor that modern power tools have removed from construction projects. I have a book on framing carpentry, and in it the author mentions that when he first started out, all of the older carpenters had bad repetitive strain injuries from swinging a hammer for a living for decades. Not so for the younger guys who had been using pneumatic nail guns all of their careers. I also have a theory that, in the US, this is why houses are so much larger than they used to be - the amount of labor involved to build one bigger has decreased dramatically.
