That all depends.  If they're handled right, they last forever, unlike paper.

That isn't a problem as long as it is copied to a newer (or the same) 
medium as necessary.

That sounds like a good thing to me.

Well, then that may be a good thing.  That which is worth saving will be 
saved.  That which is not won't.  Van Gogh's paintings will continue to be 
saved and preserved.  Mine won't.  No great loss.

The same is, and has always been, true of printed materials.  There are 
literally tons of books at LC that will self-destruct before they're 
de-acidified or otherwise copied or preserved.  They preserve the most 
valuable, those most worth keeping.

Gee, sounds just like a library.
