That is sort of an interesting question on its own. Those born after 2000 didn't know anything about the "Save Icon" ( Floppy Disc ). And those born after 2010s, might never have seen a CD or DVD.
Me neither!
Of course, in practice with optic media you may stumble upon varying forms of bit rot, scratches or recording errors so it's definitively not the be-all and end-all, but still, I've got CDs recorded 30 years ago I can still read in modern systems and that I won't wipe by accident.
