The little places are closing so those 5 here and 3 there all add up, you just don't read about it in the paper. But what you say is true.
Blacksmiths are no longer around and the skills they had are well gone. Not many kids now go out to the back shed, stoke up the forge and start pounding out a sword. CNC will/is the same. With the grass roots gone, as a hobby or a profession it wont be around in the future either.
You can call this progress and life moves on, but I think it's sad. Machining has given me great joy and the mill in the garage runs nearly 24 x 7, but my kids wont pursue metal work of any kind because if you ask them, making stuff is a dead end... and they don't get why would you make something when you can buy it. It's partly for the same reasons I think 3D printing will never become mainstream.
