I don't think that so much craft is lost, I think it has just reduced in scale. For example, I still believe that there are places where Linotype machines are available and usable, even if the number has shrunk.

Maybe this is a good example of a long-tail problem? As interesting technologies are supplanted, the number of practitioners drops, levels out at a low number for some time, and then eventually goes to zero. Then the hard part is—if people still care—extending that tail as long as possible.
