That's a huge problem with digital photography and I guess that most photos from the last 20 years will be lost. I put a lot of effort into a redundant backup strategy to prevent that, so I am very confident my files will not be lost. BUT: this is only valid as long as I take care of the backups (on- and off-site). When I am gone, what then? Then, of course, the shoebox in the attic is more reliable and can be found after 100 years. So, part of my "back-up strategy" is to print my best photos and make photo books of every trip.
i don'tthink that is a problem.
speaking for myself, most of the photographs i have made
in the past 20 years
aren't worth saving, i am sure most people
will go on living ,,
and i am certain most people who use a digital camera
don't really care if
their 20,million photograph oeuvre from 2000-2017
is lost.
most photographs seem to be selfies and belfies and foodsnappies
the
boudoir photographs they took with their spouse/lover/ex &c
is still80x120 high-gloss printed on metal
behind glass spot lit, above the louis14 chaise lounge in the master bedroom..
The OP wanted his 2 year old son when he grows up have a film camera to enjoy. I think the more difficult part is how to make his son enjoy the camera?
by the time the 2year old is in his 40s there will be an implant ...
and he won't even have to buy a camera or film, he'll just live in a
dream state (like total recall .. eternal sunshine spotless mind &C )
im sure if he tells the people in charge " i want to be able to use a leica m3 and tri x and process
my own darkroom prints like my dad used to do " they will be able to help him.
