That's not quite true- audio CD don't have the additional ECC protection that data CDs do, but they do
have the built in Reed-Solomon parity bits. You'll probably have problems if the disc shows copious C2 errors. Otherwise if you rip a CD with a tool like Exact Audio Copy, there won't be any degradation.
OTH, I'm having no longevity issues with my 40 year old 80 column punched cards.
Unfortunatley I can't find a card reader for my 42 year old punch cards anymore (outside of a museum)
and they're a bit warped...
