I'm quite surprised that CD-Rs have such a long potential longevity, though I suppose they are only a certain kind (that I almost certainly have never used when I was burning CD-Rs) that are designed to be more durable. It also kind of assumes that they're keeping them in an environment suitable for archival purposes, which does not exist in my home. Still, even the lesser CD-Rs are rated for much longer than what I would have pegged them at, given just how many CD-Rs I have that have already begun deteriorating. Perhaps the ones I was buying in giant spindles weren't advisable for archival use. I've many CD-R that I or friends have burned that have their layering flaking off, making them completely useless, and I'm sure that many people out there do as well, which is why I am skeptical of using them for anything important. In the end, for people's personal archives, they should certainly follow typical data integrity advice (i.e. the 3-2-1 rule) and also importantly, heavily curating what they choose to hold on to.
