How long will CD-R's & DVD-R's last?

Several days ago a thread was posted, in which the discussion was about how to copy tapes to cd. One of the responders, in a passing comment, mentioned that cd-r's would only last 10 years. This got me to wondering, is this scientific fact, or "audio wives's tales"? I'd be interested to hear about the longevity of recordable media from folks who are in the know on this subject.

There are archival quality CD-R's and DVD-R's.

These discs from Mitsui have a life expectancy claim of 100 years because of the 24K gold reflective surface. Even if they are wrong by 50%, 50 years should be enough for most things.
