It used to be you could find a box of photos or keepsakes that you inherited to look back on how things were or when you were a kid. Now, most of that is stored on phones, and most parents probably don’t think to share or save them in a way to be passed down in the future.
To be fair I don’t think much anyone but the parents care for the photos. The number of old photos and albums I see in antique stores and estate sales is staggering. I’m not saying nobody wants them at all, but generally unless you have something very interesting like Dad working on some important civic project or a snapshot of him in theater as a soldier, or Mom as Wendy the Welder or in a foreign country as Doctors Without Borders, most of the generic family shots of christmases and travel get filtered out into the trash.
Also, most all modern ink and paper is non-archival, so it won’t last.
I’ve had a camera on the side of my house, streaming 30 pictures per second for 12 years, I only look at about 2% of those pictures - though I have a computer that sounds an audible alert when something interesting is happening in them…
That’s over 11 billion photos, so far, “lost” from just one camera out of six we have running 24-7 now.
