The digital age moves the focus (pardon the pun) from protecting the original by defensive measures to protecting the image through replication.
If your house were to be flooded, catch on fire, etc (G-d forbid), with photos and slides and negatives, there was not much you could have done to protect those images - not without some very serious and sometimes expensive effort, like making dupes, etc. Not many people do or did that (yes, I know YOU did, but most of us didn't).
We've had this discussion before - I recall one person who argued that he had a shoebox of 30-year-old Kodachrome slides that looked fresh as a daisy, so that was clearly the superior method. I am glad his house has suffered no catastrophes, but I'll bet there are some folks in Florida and New Orleans who feel differently about their shoebox that floated away, slides and all.
Now, the onus is on YOU to keep track of your digital photos, to make copies, to change file formats if necessary (seldom needed as far as I know, but it could happen) and change digital storage media as old ones become obsolete. Yes, CD's fade. Yes, no one makes 8 inch floppies anymore. That's YOUR responsibility to keep up with.
All the examples the author of the linked article used are failures of the primary caretakers of the data. If they wanted it, it was their responsibility to protect it. That's not a fault of the digital age, that's a failure to plan.
Same thing can be said for all the movies that turned to goo in the movie cans over the years before people started desperately trying to save them by copying them to newer formats on safer film bases. Not the fault of the media - it was what it was - the best they had at that time. The fault was with the caretakers of those reels.
Banks and other financial institutions have lost lots of value in recent weeks - but they have lost no data. That's because they are on the hook in a very real way for preserving and protecting that data from destruction. So they take it very seriously, they have plans and procedures in place to replicate, backup, and test restoral methods - and it works.
If you treasure your photos - digital or film - you are the one responsible for taking care of them. That includes not letting technology pass you by, checking your CD's to make sure they're readable, getting an offsite storage plan working, making redundant copies, and so on. Fail to do that - blame yourself.
