I think the e-generation want to do everything on their phones. That's OK until the system fails, and they will be lost.
On the bright side there are still younger people who delight in using machine tools. My son in law is one such, who refurbs old machines (as a hobby), and has a shed full of machine tools. He frequents a forum where they chat about just this. He recently broke a collar casting, like a big cast exhaust clamp. One of the forumites not only repaired it free of charge, but also took pictures along the way. His brazing skills are quite amazing.
The thing is, you can't always judge the size of things on line, and when an air cylinder arrived one day, we had such fun carting that down the garden. It was absolutely huge.
