Bad take alert. I have just over thirty years of my own photos (scans too) and a lifetime of my parents photos to go through. Time has the quality of making the ordinary extraordinary and the race to purge one thing to make way for another can be passed on as a task to the next generation.
Frankly most of the problem could be fixed by screening what you put into long term storage. If photo looks bad now it won't look any better in 10 years!
There exist plenty relatively high quality photos from Christmas and other family gatherings.
Photos of ordinary things like cutting grass or milking cows however are really few and far between.
Which means some things will forever be hard to explain to my kids.
I keep almost everything except duplicates because I can always delete them later.
