My parents have saved tons of boxes of old family photographs growing up. They are fun to look at from time to time, because it used to be a bit harder to create photos. I wonder if the next generation of people will collect moments the same way we used to, seeing how quick and easy things are posted online. I’m sure many of them don’t even have pictures saved locally somewhere and rely on social media and the cloud to store their past.
You get a good number of data hoarders after a picture provider goes down/enshittifies. Yes, they’ll lose at least one large collection of photos. But I suspect many folks realize they could be banned, lose their account, etc, and take some effort to save things that matter.
