Entertainment and/or fulfillment is most of the value in most books. Whether or not a book contains directly actionable information is mostly dependent on what you are trying to do. For example, a book about Kubernetes is only directly actionable when working with Kubernetes. At random, a human being is unlikely to use Kubernetes. So a book on Kubernetes usually doesn't contain any actionable information.

Suppose you read a book on Kubernetes today. You don't use Kubernetes. So you read it just because you are curious. That's the value of most books. If three years from now you start using Kubernetes then the book suddenly becomes directly actionable.
