Disc rot is so overblown I'm genuinely convinced companies are influencing discussion around it to scare people away from optical media.
In the, probably near 1000, discs I own
I have one with rot, and that's a CD manufactured in a specific plant, within a specific timeframe known (for decades now) to have had issues.
So it's not as if it's a random occurrence which has caused that disc to fail, but posts like this always seem to push the idea that "your disc could just die at any time bro" and it's simply not true.
