Play-Based Childhood versus Phone-Based Childhood:

Josh Zlatkus:

"The modern world places novel demands on our Stone Age mind—demands it is not always equipped to handle. Modern childhood is an obvious example. Many readers will be familiar with the argument, popularized by Jonathan Haidt and others, that “the loss of ‘play-based childhood’ and its replacement by ‘phone-based childhood’” hasn’t been great for the mental health of children and teens."
