Since the Gutenberg days there has never been a shortage of written material to be digested. For hundreds of years there has been way more written material than any one person could read in a lifetime. So the problem has been to pick out what is most worth reading out of the millions of books you could be reading instead. The situation now is no different, except that we should have stricter standards on what information we allow into our heads. There will always be value in a well-curated library (will AIs curate the libraries too?)
