Hot take: why? Why is reading _better_ than gaming?
From an "entertainment" point of view I very much doubt it. I see it as snobbish.
From "productivity" point of view, well games have never been a productive thing so why comparing apples to oranges?
From an "educational" point of view stuff doesn't differ much that from a productivity point of view.
Then again, if you have non productive time to slot where you can do anything, why are books the "superior" choice?
Context: Yes, I do play games, but I also read 9-10 books a year.
