I wish no-cost photography had been the norm when I was a kid. I experimented with black and white film developing as a hobby but every click of the shutter cost money. Compare that with today's essentially free digital photos and you'll see why one reason why most of my photos are only a few years old.
Nowadays, I really don't think one can take too many pictures. I'd like to be able to see images from nearly every point in my life. For example there are a million things from the early 1970's I wish I could view. Although I remember running around Nielsen's field taking photos of objects like apple trees, the only pictures I have from that era are family snaps. Seeing the people is interesting; however, I'd like to have a look at neary anything from that period of time.
I have no photographs of these things, so I doubt I'll ever know the answers.
