Carboloy

Awesome! Very neat video. Video raises interesting social questions. Seems like not much has changed! Except instead of work getting easier with people making more. Interesting too to note the diesel electric trains, and other factors. Seems like we have refined what existed then, but not much else has changed!

It's just like everything else. Air travel, computers, CNC machines, etc. In 1928 you probably had to be one of the 5 richest men in the US to get your hands on some carbide cutting tools. Now you can buy carbide tipped masonry bits at any hardware store for a few dollars.

Pretty neat.
