On one hand I get your point, but on another if you spend most of your time learning (but through other formats than books: through quality online articles or videos, and not eBooks) then it does not seem so bad to me.

I am reading nearly 24/7 but I complete a full actual book maybe once a year. Might be bigger if you count the books that have also (legally) been wholly posted online, but I often forget them because I read them just like an extra-long article: on my phone. I read peoples' original fiction that they post online so I'm not sure whether to count it or not.

I like longer articles but I do admit that I consume so much less long-form content than I did as a child. At least I avoid TikTok and Reels and the like? (Not to be elitist, but because I know I specifically would get addicted and waste my life. Very bad for my particular ADHD brain.) Also something something possible link between lower attention spans and only consuming short-form content. So I get the general gist of your idea and agree even if I do not particularly agree with the emphasis on the medium of books.
