The information on the internet is unbounded. You know this, you are aware even if subliminally, no matter how you control your browser by blocking ads, pop ups etc. An unbounded information horizon is destabilizing. There is always more (possibly better) information a click away. It's hard to justify keeping attention on just one article. I even read a paper newspaper article with more attention than the same article online.
Of course pop ups, ads, the incredible commodification of attention, has made this much worse, but the problem is inherent to the internet.
When I open a book, there are two covers, marking beginning and end. It's awesome. In between is a place for deep attention.
There have been books that have enriched my life. It's deep focus, not shallow scanning. I think there is something soul crushing about the shallow attention we are left with after years on the job. (Slack & Teams are part of the problem.)
