Same thing happened to me with podcasts and articles. Used to feel guilty about "reading" stuff with my ears but then realized I was getting through way more books than I ever did squinting at pages. My sister is a school librarian and she told me the whole gatekeeping thing about what counts as reading is mostly people being snobs. Brains don't care if the words come in through your eyes or your ears. Now I do audiobooks on my commute and paper books at night and honestly stopped keeping score. The story is the point, not the format.
