A medical journal once railed against the dangerous combo of mental overstimulation and physical inactivity they believed threatened the well-being of children everywhere. The cause? Literacy and the newfangled institution peddling it (you know, schools). If that 1880s panic in the parlor sounds eerily like screen-time warnings, it should. It turns out basically all new tech—from written language to the printing press to smartphones—has made humans freak the heck out. Experts say the better tactic is to embrace technology, providing kids tools and guidance as they build tech literacy that will last a lifetime.
