It is interesting, could you say more on how old were CD-Rs that failed and what percentage roughly failed? Also how were they stored? I hear a lot of this information, but personally my experiences are diametrally opposite. I've never used cdrs to store really important data, I have all this on hdds, but about 30 20 year + old CDRs I recently found in my storage (stored in a dark cold - sometimes wet basement) are all fine. Same with hard drives that haven't been touched for the same amount of time.

The CD-Rs were around fifteen years old, stored in plastic boxes in my house (in rooms with HVAC). A couple of them failed in a set of twenty or thirty I think. I do have 20+ year old CD-Rs that still work fine though. For hard drives I have had ones that were mysteriously corrupted after being unused for six years or so, but others that were readable after fifteen. It partially is the luck of the draw.
