Yes, the older ones of the rotating backups are still readable.
But that’s not even the actual problem nowadays: CDs and DVDs were nice when their size was still relevant in comparison to usual amounts of data. The real problem behind their decay is that we are lacking a widely available, properly scaled backup solution for more than a decade. So the mean reason people have now unreadable optical data is that they stopped thinking about it a long time ago for an utter lack of options.

Well, there are 100GB and 120GB Bluray M-Discs. But yeah, the only things larger are either spinning rust (i.e. HDDs that need to be refreshed regularly to prevent bit rot) or very expensive LTO hardware and tapes.
