Same with reading actually. Reading a book makes you think for a long time about the subject and form your own judgments. I like audiobooks and online content too, but they don’t seem to stimulate this nearly as much.
For audiobooks, I seem to not have as much of a tendency to pause the audio and stop and think, and it’s harder to reread a passage, so it’s a more passive experience.
For online content, there’s not as much of an intention to fully engage with the material. It’s easy to skim or switch to something else.
