Don’t conflate a mastered CD with an aluminum data layer with a recordable CD-R or CD-RW, which use organic dyes that have a significantly shorter lifespan.
A properly manufactured CD can last 200+ years if it’s stored in a dry environment free of UV exposure and high levels of moisture.
Even a quality CD-R can’t really be expected to retain all of its data integrity for much more than 10 years.
Obviously no one’s seen it happen first hand. It’s a projection based on what’s known about the materials and how they’re made. Burned CD-R’s have definitely been out in the real world for people to learn how short their lifespans can be, though.
Nobody could “prove,” for instance, that the Voyager 1 could stay operational in deep space for 47+ years when it was launched in 1977, but the engineers could still predict and they launched it anyway, and it did. I don’t think your argument really holds water.
That’s what I think when I read endurance/mtbf of hard/solid state drives of like 100+ years. Bitch you released this last week and I know for a fact that you didn’t withhold sales for 100 years for validation of your claims. Also funny how I should reasonably expect 100 years out of it, but you will only provide a warranty for the first three…

Sorta doubting whatever study found proof that a CD can last 200 years…
