This is going a little off topic, but I think the big problem is the 'delete' button. I'm a historian by trade and we fear a future where the quality of our data will be much reduced. Government files will always be backed up but what of the shoebox it the attic full of letters written hundreds of years ago, forgotten photos, old dairies. Nobody writes anymore they email and blog and then they get bored and delete the lot, same with photos - only the dedicated snapper backs up, most photos never leave the mobile they were taken on. I often wonder where our future material will come from.
Our common history, so much more fragile than we realize.
The delete button is something mentioned regarding photojournalism too. Sometimes an insignificant photo becomes significant later. The famous Monica Lewinsky with Bill Clinton photos are often cited as examples. Will all today's images be stored the way negatives have been, and if so, will they be accessible?
I'm sad that what will be lost is the collective record from the pictures ordinary people take. I have pictures from the past 40 years or so that I thought little of at the time, but which have a lot of value to me now. They show people who are now gone, places which are now gone or have been forever changed. They show how things looked, how
we looked then. I now wish I had taken many more pictures of just ordinary things. I find a lot of young people are fascinated to see how things looked "way back in the olden days" like say, 1990.

Now, pictures are taken constantly, especially by the young folks. But will they be preserved?
Not too long ago I found Kodachromes of my first Christmas, with my parents looking so young and my brother all of 5. He turned 60 last week. The color is vivid and true. The cover of a book which I still have today looks the same as it did in those pictures. Those slides have spent the last 50 years in Keystone slide trays on a high shelf in a closet, in this house. Being up high, they have been subjected to considerable heat during the summer, and not a whole lot less in the winter. But they're beautiful.
Some of the jpegs on floppies I took 10 years ago with a Sony Mavica corrupted within 3 years. I do have an archaic device called a floppy disc drive

with which to extract them, but a lot of them won't open or only do partially. And a scan of a print put on DVD in '03 doesn't open either.
In contrast, I don't have to open images on the old slides-just the boxes they're in.
No decoding needed-they're in "direct optical read" format.
But then, so is the oldest photograph in the world, still "readable" after more than 180 years. Without even having to be recopied periodically.
