Back in the 1980s, just giving kids a computer (without also giving them a bunch of game disks/tapes/carts) would certainly teach them something, in that the only thing you can really do with this "tech" is to fiddle around/tinker with it until you learn how to make it do something you came up with. Just sitting around "being bored on" these computers can—and did—gradually build up a skillset in many of us.
There are still computers that are like this, of course. The Arduino comes to mind. There are also environments you could lock a modern computer down into that do the same.
As well, there are apps and "games" that teach you a ton just by attempting to understand the model behind them, which bored children will stumble into and then learn from under the guise of "wasting time at recess." (The best thing you can preinstall on a computer that a middle-schooler is going to be using is an interactive kinematics sandbox program.)
Can you convince me that any of those assertions is wrong? Pointing out that "YA fiction is literature" doesn't come anywhere close to refuting any of the above assertions.
Even in a for-kids/for-youth book collection, where we used to have Jack London, Jules Vernes, James F. Cooper, Alexandre Dumas and so on mixed with more specific children's literature; I looked at the current catalogue the other day: such authors have been erased, and the whole offer is now made of novelisations of Star Wars, novelisations of cartoons and novelisations of comics... Oh you can still find them in other collections, but those are a bit more, how to put it, distinguished/smart collections (and aimed at a bit older age); so that was quite a shock to browse the catalogue of the 'standard' kids collection.
Well, as opposed to, say, watching TV (or the somehow even more mindless content that’s on YouTube), do you really disagree?
Perhaps a bit more fringe: I think a lot of light young adult fiction has the nutritional density of popcorn and any perceived inherent good in reading those books is likely a product of publishing industry propaganda campaigns. Scholastic Corporation, I am looking at you...
But later on it definitely matters. I had this same struggle with my daughter when she was in middle school -- she got so many kudos for "reading so much" but the books were all filler. I tried many times to point out that books are just a medium and the content is key.
It seems apparent to most classroom instructors that most tech is a distraction, not an enhancement. Obviously exceptions should be made for disabilities and there are some uses—spaced-memory repetition software or some computer science classes can use tech effectively. But in most classes it's detrimental rather than helpful.
