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.
A drop in the bucket compared to those that were never taken at all in the last 4,000 years of civilization before the picture boxes came to be.
