I think that looking 10 years in the past is not a reliable way to interpolate to 100 years in the future.
I think you're wrong, specifically because I'm not only looking ten years in the past.
I'm comparing the arc of the consumer computer industry with the arc of
every single other consumer industry in the history of mankind.
Once something is thoroughly commodified in the consumer sphere, seismic shifts do not come fast and furious. In the real world, people who wanted to save the data on their 5.25 floppies had years of overlap with other technologies to do so, and still can--and that was even before the commodifcation of the microcomputer industry was complete. There is simply nothing, nothing, in all of human history to lend credence to the idea that the media used by basically everyone in the western world to record most of their data will, with any swiftness whatsoever, become obsolete and unusable.
Point me to an exception, please. Nobody can, because
none exist.
The point being, one more time: in the real world, people who care about their images will find film or digital exactly as easy to carry forward as the other.
People who don't, will without any doubt at all have less trouble getting files off a forgotten hard drive in 100 years than they would restoring a bunch of slides that have been molding in an attic for a century (someone will likely be able to do it, but it will cost five years' salary for the average person).
Face it: film and slides deteriorate and rot, are lost to fire, are simply ignored and never looked at. Almost nobody takes care of them properly. For those people, their digital files will be no less accessible in 50 or 100 years than their film images.
Nobody has been able to provide a rational support for the contrary viewpoint.
