This is lame beyond believe.

Do you know how in the 80's and 90's everything that everyone was already doing was 'changing' because of computers.

it's the same now with 3D printers. Forever you could duplicate a key in a machine with just a picture of the original. just because the machine to duplicate it become easier it's not going to change the world. dammit you could already do the same with a blank and a hand file, it would just take 40~200min depending on skill instead of 5~15min on the machine.
