Yeah, that's fair, in this sense they obviously mean "internet/modern technology" but it's funny to me that the "take a break from tech" isn't to go for a walk or reflect, but instead it's "Go consume a different form of media!"
Just like you wouldn't lump tiktok comments and a thought-provoking book into "reading".
you can get profound insight from random youtube comments. A book can be a waste of time.
To separate them is to put a value on it that isn't there by any objective measure.
I'd argue "take a break from tech" does definitely involve putting down the books. go be with yourself for a bit. let your own thoughts develop, go "touch grass"
