Sometimes it does feel like a task but when I finish a book or even a chapter that I liked I feel happy and satisfied for what I just did

Definitely, this new entertaining system is highly incompatible with traditional reading habits (at least for people whose attention is not great)

Exactly, it feels like the thing I'm reading is never "enough", it's never entertaining enough for me to be doing this.

I definitely think that TikTok and YouTube short videos have something to do, we are getting used to be permanently entertained and if anything bores us we just swipe and go back to being entertained. But I don't think that's the whole reason because it's something that has happened even with entertaining readings
