Was using and programming CNC in the early 80's and many of those machines were from the late 70's
They have just become a bit more intuitive over time.
Not only have they become more intuitive, the CNC machines available today are MUCH more capable and at the same time more affordable. I am constantly amazed by the parts we design machines for these days. Even 10 years ago it would have taken multiple machines to realize a solution that a single machine can easily tackle today.
