Of course, they're still better . . . for the time being. Unfortunately, wood has a useful life, it's measured in hundreds of years but it DOES wear out. My mother in law gave me a book that is a survey of some of the great instruments, and the author noted that there is a horizon line beyond which they are going to start to fail. Some of them are preserved in nitrogen-filled cases and never played for precisely that reason. Which is a shame.
But the average quality of violins continues to improve. Even the mass-produced Chinese ones sound remarkably well for what they are.
I would hope so. We have so much more to work with than did some guys in some European villages.
