When I have kids (or if I ever run a school somehow), I would give my kids hackable, terminal devices that could connect to the internet with work. Both sides are doing it suboptimally. The anti smart phone crowds are suppressing kids natural desire to look for learning and new experiences outside of taking exams. The smart phone crowds underestimate the power of these multi billion dollar addiction engines. The optimal solution is to work with the children's natural curiosity and provide them a runway to growth.
