I think the main issue with this line of reasoning is that before all of these internet based forms of content, did many people actually read literature, like is mentioned in the article? I am not sure, but I would expect that the books that were read were probably not some high form of art but entertainment - which is fine of course, and it is different to a large extent from scrolling tiktok, but does it like up with the authors thesis about reading providing some deeper form of enlightenment? Maybe it still does, since it's still the same act of reading, but maybe not as much, since it's not normal "intellectual content"
