A picture of a rock might or might not provoke any particular thoughts about rocks in the viewer.
But if I write anything more than the purely descriptive "there is a rock" then I have conveyed some sort of thought about the rock or rocks in general, and at the very least you have been introduced to my thought, and very likely you have also reacted with some thought of your own. And the mechanical process of reading gave you the time and venue for that to happen.
Even if I do try to be purely descriptive, it's impossible to seperate my perception from the output. I can only describe what I noticed and considered noteworthy. I litetally cannot write the equivalent of a photograph of a rock, but can only write my thoughts about that rock.
The photograph may contain more data, but no opinions and no understandings. The viewer can possibly have no thoughts at all about it, and not actively notice most of the data, or the significance of various bits of the data, but the reader must have at the very least the thoughts of the writer, and it will be almost impossible not to have some sort of thougts of their own in reaction to reading the writers.
Other things also provoke thought, including video games. But I only asserted "more".
An incurious person can fail to think about anything at any time.
And you fail to think about games. Interesting what you say about yourself.
It is a contrived exception because you have to pick a special video game and a special book to make it work, and the example will not hold when picking 100 books at random and 100 games at random, and that's even granting that the cherry picked example even holds, which I actually deny.
The tone of your post suggests you're refuting this wholesale. I think you're wrong, reading books makes you smart(er) at least by expanding your vocabulary and widening your understanding of the world by putting in front of you experiences from people that are not exactly like you.
You're offering video games as an alternative, but people that invest a lot of time in playing video games as opposed to reading, usually do it with terrible games, where the lesson to learn is that life is expendable, enemies must be stopped at all costs, genocide is valid as long as you're the main character, etc. Games as art form rarely engage people in the same way as mass murder types of games. What are the sales numbers of Disco Elysium vs Call of Duty?
And yes, pulp exists in writing too, probably to an even greater extent, but at the same time the peaks are higher and, in my opinion, the benefits, as subjective as they may be, greater.
You make an almost credible post but then totally undermine it with this statement. It's rather like saying Looney Tunes is bad because the intended lesson is that you should set your cat on fire.
My problem is not that games make kids shoot schools, is with the fact that games in order to "be fun" and have people play them need to follow this recipe in the first place. The violence is probably intellectually understood as "wrong" by the large mass of players, but in my opinion it still desensitizes and erodes normal reactions against it to a level that should not be acceptable.
