> if LLMs give us immediate summaries of every page stored in them
I assume very few people go to the library currently to read a summary, why would this change in the future?
The premise of all your questions assume others agree with you that books will be replaced.
The web has been "replacing" books for a long time. Books still exist.
I think LLMs will make knowledge in older books much more accessible via modernization and reinterpretations of now-Copyright-free stories from the past.
