Who are we?
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

I had some CD-Rs that rotted within a few years. I was devastated, because at the time CD-Rs were hyped up as the most durable of any consumer media, and storage was expensive. I had tons of stuff that was ONLY on CD or DVD. That's how I archived everything.
There was an old site that did a comprehensive analysis and ranked different brands of CD-R and DVD-R discs into tiers. My main takeaway at the time was Verbatim or bust. There were some other brands that got discs from the same manufacturer, but not consistently so it was something of a gamble. IIRC Sony was one of the better ones, but Verbatim was the safest choice.
I can't say I've tested any of my old discs in the past 10 or maybe even 15 years. I copied my most important data into newer media, but I still have a ton of discs I should probably clone to my NAS. One of these years...
Then came M-discs, which as far as I know are still considered legit. They never really caught on, and production has either halted entirely or is at least limited. I never used them myself.
