Humans have a built in desire to gather and share knowledge. We are a social species and evolving ways to communicate and share our experiences in order to increase the overall knowledge of the whole community increases our chance of survival immensely. I would say this communal sharing and understanding of others perspectives in order to strengthen the whole group (empathy) is the greatest achievements of our species and what makes us human.
People take for granted that the ability for a species to have information learned through experiences be passed on and not die with the experiencer. Not many other animals have that. I think this is why most of human culture has a strong culture of story telling and remembering our ancestors.
We stand on the shoulders of giants to see further than they could. This is why the loss of education, the warping of history, and loss of media preservation is so tragic. It leaves us in a loop of having to relearn the lessons we already learnt. That's what happens when you atomize and hyperindividualise a social species.
Imagine if we didn't have this tendency to store and pass knowledge? Imagine not knowing what germs are, not knowing to wash your hands, not knowing which food is poisonous? Imagine if every individual had to come up with the invention of the wheel all on their own?
So yeah, librarians and archivists of all kinds are cool and it's natural to want to be one. I don't think they're valued as much as they should be.
