It is easy to imagine a world where not only can few people read, few need to or want to. Serious reading can become the preserve of a s mall group of specialists, just as shoe-making or farming is for us. Think how much time would be saved. We send children to school and they spend most of their time learning to read and then, when they leave, they never pick up another book for the rest of their lives. Reading is only important if there is something worthwhile to read. Most of it is ephemeral. That means an oral culture of tales told and remembered. People can be immensely sophisticated in thought and understanding without much writing.
