Frono, I did not read the article. I know bad form. However, the analogy of magnetic media and chemical media is not a great one. Magnatism has a longer life than a very thin film of chemical emulsions. While digitally scanning the results may allow someone to guess at the details lost, film doesn't have pixels, really. With color film, certain colors go off first. I think the reds. and then others. It's not like color film is just black and white details with color shading. Some of the detail IS the color. A persons face could almost go clear on a slide film, if they weren't cared for properly.
You might be surprised. Data backup is a HUGE issue and one that most of us take for granted. Hard drives go bad, and it can happen in surprisingly short amount of time. Take this article: https://blog.storagecraft.com/data-storage-lifespan/ While I don't necessarily agree with those numbers, but when you've been in and around IT as long as I have you absolutely see data "just go away". I've seen hard drives that someone stored "for safe keeping" be practically useless after just sitting in a safe deposit box for years. Same with tape, same with everything that holds data. There really is no such thing as data permanence.
Of course I've seen the opposite, too. A floppy disk that sat in my drawer for 15 years read perfectly when I found it. The problem was finding a floppy drive!
I don't discount your point about undeveloped film, though.
