I find that a copout answer. Screens are inherently distracting. They literally flash and flicker. The devices that those screens are attached too have buttons and little jiggery bits. There's a ton of distracting software on those devices, browsers, games. The supposed learning software is all about gamification and slidey swoopy menus and other completely distracting BS. So yes, "screens" as a pars pro toto for digital learning is inherently distracting. It's only when you reduce it so far as to be meaningless, - "a screen is just some LED-lights organized in a square, how's that different from paper," - that you can say they're not.
