CNC is cool, and you can do some pretty amazing things e.g. with a 4 or 5 axis machine, but ultimately the value is in repeatably churning out the same part over and over again. The industrial utility is obvious, but there's not a lot of pedagogical utility and to a hobbyist or prototyper it's generally just not worth the overhead.
