I don't think novelists have yet figured out how to completely occupy your cognitive apparatus or put you under pressure to stay engaged. When I'm sitting in my comfy chair reading a novel, I can close my eyes without worrying that I might miss something while I'm asleep.
How is this different than closing your phone, screen shotting a FB post, pausing your video? Really. Even live streams, for the most part, are able to be paused and watched at a later date albiet without chat interaction. I fail to see the difference.
If you fall asleep during a video, now you'll have no idea where you were. Similarly if I lose concentration watching a video, I now have to either go back or hope I didn't miss anything important. If I lose concentration while reading, the page is still there, I just have to skim it until I find where i went on a tangent.
You really don't see a difference between skimming a single page and scrubbing through a video that could be hours long? And scrubbing only works when the video is visually distinct enough between parts that you can tell without having to watch a few seconds at multiple different points.
