Same thing that happened when the internet became a thing (or is still in process of happening in many cases).

The things we need to learn change, and shift to adapt to how the works works. You don't need to know the Dewey decimal system anymore, but you need to know how to find information and determine which is credible. You don't need to know how to write cursive anymore, but you do need to know how to present your ideas in a way that other people will be able to understand them.
