Mine work now for almost 40 years. And don't forget: floppy disks have mechanical attrition.
The floppy disk lifetime was, as always, an estimate. My 5 1/4 disks for C64 seem to be the way more robust product compared with the 3 1/2 for Amiga and later PC. Maybe information density plays a role here.
CDs have the reflection layer problem, not the information loss per se. That's the main difference between disks and CDs.
