You were generalizing, I showed you an instance were what you said didn't hold; and I know more cases. You bet that train videos were boring to kids and I proved you wrong in the general case.
> Is a switched off screen addictive too?
This question is absurd. A switched off screen is, for all intents and purposes, not a screen.
My argument is that my kid and many others are instantly attracted to screens as long as they show motion and sound, and that it doesn't have to be a children's cartoon or song.
Switched on screens remain powerful attractors for many children.
