So, I might have gotten this wrong, but it was my understanding that CDs and DVDs (at least the writable kind) use an organic (carbon-based) layer for data storage, which is why CDs and DVDs succumb to disc rot over time. Blu-ray, however, shouldn't have that issue because they don't use an organic layer. I might have misunderstood that though.

Writable cds and dvds use a bunch of different technologies, but they are an aside to the conversation here.

Disk rot when it's used is generally always used when talking about pressed disks not writable disks. Dvds, cds and blurays all use variations on the same technology which is stamped plastic with a reflective layer at the back made out of a metal. No organics.

Thanks! I didn't know that, I assumed normal discs were just pre-written [disc]-R with special printing on the label.

Does that mean pressed discs can be potentially fixed by carefully peeling off the metallic layer and applying a new one?
