That just means exploiting the medium to full potential hasn't been normalized yet. Much like with the books, you can pause video and audio. And, much like with books, you can go through the material once to get the high-level overview, and then play it again to learn more, now that you have better feel for how things fit.
I've noticed that both pausing to think and playing the same work couple times in a short succession, are something people are reluctant to do. Writing this, I've noticed that myself I am reluctant to do it too, for no apparent reason. Might be because people my age and older, we weren't forced to learn from videos or audio during school and university years, so we didn't internalize the same consumption patterns as we did with books.
