Right, the argument against screens shouldn't be that they aren't natural. It's not "natural" to go to the gym and do repetitive contrived exercises, but this turns out to be a healthy habit. On the other hand I don't think any great leaps are required to be wary of the effects of screen time. Even as an adult, if I get into the habit of scrolling through newsfeeds, I notice a strong effect of being distracted and seeking stimulus when doing work. My brain has been trained for quick hits of novelty. In general, there's a night-and-day difference between activities that are easy and tempting vs. challenging but rewarding. I'm sure there are some great educational games on the iPad, but realistically the vast majority of screen time falls into the easy and tempting category.
