I think you and the previous commenter have very different opinions on what "all" means. Connecting to parents and grandparents by knowing what art they like is one thing, but, for example, I have hundreds of photos of random bills and documents that I need to remember for later. None of my descendents would ever want to read through that unless they were investigating my life like in a movie.

My most frequent type of data in my personal archive is screen shots of tumblr posts that my oldest child like to take when they were 12 and we all shared photo saving account.

I do snap bills and white boards to remember but not with the eager enthusiasm of the long since grown up child.
