I have nothing against audiobooks, but they are not the same as reading. It is a passive consumption of the content. You can daydream or lose focus and the story keeps rolling on. If you lose focus while reading, the story stops. You may find that you've "read" a few sentences, but it's quickly self-correcting.
Additionally, reading forces you to parse tone, interpret context, and resolve syntactic ambiguity on your own. Listening to a narrator removes those tasks.
I think that this door was opened when we started accepting that reading graphic novels was the same as reading a book of text. Rather than elevating new(ish) media for storytelling for their own merit, we've lumped them into another medium that was already deemed "good".
All that said, listening to an audiobook or reading a graphic novel is still better than not reading a book at all.
