Nah.. It does benefit me. Having a CNC cut the stone is far less labor intensive. Having a hoist to move pieces is much less strain on my back and body. The productivity rate is only changed marginally, the machine runs for an extended period of time allowing me to basically stand and watch. If I had to hand fabricate everything; I would be working, much more intensive labor, non-stop until the fabrication is complete.

Longer and harder compared to what? I work as a granite fabricator, I use cnc machinery, if I had to cut and shape all of the countetops by hand I would be working much harder and longer.
