The Irony

As I was reading the novel The Shallows by Nicolas Carr, I noticed something ironic, but also hilarious. His first chapter describes how the internet  has changed our brains and attention spans, and how most of us can't even get through a paragraph without getting fidgety, much less an entire book. Yet, Carr writes a book. He writes a book, about not being able to read books. How does he, who also confesses that his mind is hungry for the internet, expect us to enjoyably and attentively read his book if we, as teenagers, are worse than him?
