The role of the librarian has become increasingly unnecessary. Why?
Because ancient databases have evolved to become more user-friendly. Librarians aren't the lone guardians of information anymore. Knowledge has been democratized.
Is this a bad thing?
No. This is a wonderful thing. 99.99% of the populace benefits. But there will be less librarians needed. Some say I'm cold for not thinking of the .01%. I say you're out of your mind for not prioritizing the 99.99%.
