Agreed. I also tend towards Save All The Things, because Future Me (or my kids/grandkids!) might feel differently. I'd prefer to err on the side of having too many pictures, than only having a few. We can always cull them later, but it's hard to bring back what has been discarded.
If you have someone in your life who likes to do genealogy research, talk to them. You might also find that you would have been Very Interested in seeing what your grandparents did in their spare time, hear how they spoke, and so forth.
30 years from now, my kids will (I hope) be starting their own families, and I'd like their kids to be able to have insight into what their parents were like as kids, or what I and my wife are like as parents.
I liked looking through my parents' photos as a kid, but there was a couple of photo books at most. I can't imagine my (hypothetical) grandkids sorting through 60 years worth of digital photos unless software has gotten a lot better.
The busy work and stress of dealing with digital photos has actually caused me to take fewer photos. I have a preservationist bent and I just don't want to deal with organizing them.
that's the sad part - few photos available made each of them worthy inspection, bringing memories etc.
now, having 100 GB of photos & videos from somebody's childhood will either produce ignorance of whole content (no, nobody will ever want to go through all of them, guaranteed, and if yet they would hate it), or some automated way (yet to be invented) to take out best maybe 100-200.
By not selecting few good worthy now, you're just pushing the decision into the future, to your/somebody else's shoulders.
