Optical discs are already incredibly resistant and shouldn't be expected to fail in your lifetime. Most of the times they do, it's either old media (cd and dvd both had physical flaws in design), damage, or mistakes in manufacturing.
There's really no reason for the discs to degrade. It's just stamped plastic.
The foil coating usually deteriorates first
On cds, yes. Technology from the 80s, designed in the 70s.
