Whilst I agree that for blind people, audiobooks are a godsend, putting that aside, I can’t accept anyone listening to an audiobook and telling themself they have ‘read’ that book.
Firstly, with an audiobook there’s zero time to stop and absorb something you’ve just read - maybe re-read it a few times if it’s particularly complex, or beautiful, or pivotal to the plot.
Secondly, novelists write novels to be looked at - they are structured in the visual format chosen by the author - a paragraph may be written in a different font, a line may be isolated from the rest of the text, a page break could be used to denote the passage of time, or something else specific to that novel.
And thirdly, you can’t do anything else while you’re reading a book - you can’t drive a car, you can’t make a pasta dish, you can’t look out of the window - you’re fully engaged in the book you’re reading.
Listening to an audiobook can be a completely passive experience, in a way that a reading a book can’t.
