Screens and computers are incredibly useful in education when they are used for some concrete purpose. Just think about how incredibly useful it is to use Desmos or Manim to explain certain mathematical concepts, as opposed to chalk on blackboard or print on paper.
Replacing a paper book with the same pdf on an ipad screen though, has to be one of the most stupid ideas anyone could come up with.
This is all downstream of the backlash against social media and AI, and it's attacking the symptom rather than treating it IMO. You don't need to abandon digital tools entirely, you need to control how they're used in the classroom.
Not every kid can learn concepts just by having them explained verbally or with simple, inanimate diagrams. Desmos etc were incredibly valuable for unlocking certain concepts.
Also, you can't ctrl+f a textbook. Sure, you might find what you're looking for in an appendix or ToC.
