Well. Had I not done so, the photographs I shared earlier this year with my former classmates would have been lost forever and nobody would have even remembered them. They were taken on film and printed on paper, but the originals are long lost. What survives are the digital scans I made some time in the mid-1990s and that I 'found' with 3 clicks in the folder I saved them in 30 years ago. Since they're digital, they simply replicate onto whatever next medium I use for digital storage. As said, the originals (supposedly much safer/more robust) are lost, destroyed or God knows what might have happened to them. They're gone, in any case.
This problem of a gap in people's archives is not the fault of the technology involved or the companies behind them. It's the lack of attention, recognition and discipline of the owners of these data. These data weren't lost because the technology was flawed. People were careless. It's the same reason why there are so many albums of faded color prints while the original negatives were chucked, and that's only in the cases when people even bothered to put photos in albums (or even boxes) instead of just piling them up waiting to be incinerated after the next Spring cleaning.
Let's be fair here - this is not a technological problem. It's a psychological one.
Also, plenty of people don't even care/mind that they lost some photos. On this forum we're preoccupied with photos and preserving them. We're biased. Personally, I couldn't care less about some (to me) anonymous family's lost photo archive. It was their responsibility and insofar they cared, they could have elected to preserve their data. Whether or not they did, is not my beeswax. As a result, I don't quite get the lamentations in the linked article. Yes, sh*t happens and luck favors the well-prepared. Nothing new there.
I think this article was not written by someone in your age group, so (hoping I'm assuming correctly and not offending you) someone who's slightly older, might have already been a settled professional in the early 2000s, and someone with the know-how and/or discipline and/or time to methodically backup their media, whether digital or film. Somebody perhaps prepared for the 'watershed moment' (mass analog>digital + mobile phones doubling as capture devices) or having the time/desire to prepare.
I think who wrote this article is in my age group, a late millennial who in the early 2000s would perhaps be at University, or rushing to finish it, or hunting for their first job, flat sharing, moving often and possibly far away from being settled and having the time to think about storage and backup. This digital revolution hit us like a train in a very busy and confusing period of our lives, and many people were simply to busy to readjust to the deluge of media. Does that make people 'careless'? I like to think people need time and have priorities.
In those years I was moving from shared flat to shared flats, I was stressing about exams, theses, job hunting, girlfriends, leaving friends behind due to a move, and the article touches a nerve: where are my early digital pictures from those times? I do remember I owned a lot of CDRWs (I remember we'd buy them in stacks of 100 or so at the time, or was it DVD-RWs already) and that I probably burned most of my images on that kind of physical media at the time - the question is where are those CDRWs? They are probably lost in one or more of the boxes I filled with my stuff during my nth move, hopefully I can still find them.
But I agree with you in one thing - at the time in spite of having switched to a digicam like many, I still held onto my Nikon F100, which had been my first prized teenager purchase (and what a disappointment it was...) and I shoot a lot of (then cheap) Sensia slides. I had a film scanner I'd bought new (a Minolta) and the mounted slides still survive, as well as some of the scans I uploaded to Flickr when it became a thing (I think 2006 or so).
