For a while, we had the "maker movement" and "maker spaces", and people were learning that stuff. But that all tanked when TechShop went bankrupt.
There are still maker spaces around, but most of them are now more into sewing, paper folding, and hot glue than CNC machining. Few go beyond a 3D printer. The ones that do tend to have some kind of subsidy from a larger educational institution.
We used to have shops in schools back when funding for education went to education instead of administrators.
That's not been the case for a generation so no one under 70 even knows what we've lost.
