I think this is extremely overblown. I have DVDs that are 25 years old that spent 10 of those years in an attic and have no issues whatsoever. I ripped all of them, plus Blu-rays ranging from βnewβ to 15 years old just a few years ago. Several hundred discs, zero issues.
Yeah, that's a big reason that I wanted to (hypothetically speaking) rip all my blu-rays and DVDs.
Rip them while they're still good, and store them on a RAID hard drive cluster with proper error correction, and I think that as long as I'm a little vigilant with scrubbing and replacing drives when they fail, it should last quite awhile.
