"Although the so-called "disc rot" does exist, the reality is far less alarming than we might think. In fact, the industry's own estimates put the lifespan of a CD, DVD, or Blu-ray disc at several decades—and, under the right conditions, up to a century."
Only on burned discs back in the day. CD-Rs and DVD-Rs. A lot of those were cheap and weren't intended to last. Modern pressed discs were designed to last a lifetime. They should work 100+ years now as long as they are in the proper environment. Most disc rot examples are actual manufacturing defects, or discs kept in super humid conditions.
Disc rot is completely overblown. Your discs will outlive you as long as they are in a climate controlled environment.
Yes. All my sega CD and Turbo library are gone due to rot. Some of my PS One games are starting to go. DVDs for PS2 seem fine so far, but some of my DVDs from 2000 to 2002 are crap now. All Blu-ray discs are fine. I have lived in arid mountain zones, , the Caribbean for 4 years, extreme California desert for 7, now I'm on the humid East Coast.
