In his book, The Anxious Generation, author Jonathan Haidt confirms our worst fears about what happened to Generation Z, the first generation to go through puberty with constant access to the internet. He writes, “… it was not merely that playing and socializing had shifted to phones, tablets, and gaming consoles but that real-life pleasures and risks were also disappearing: rough-and-tumble outdoor activities, opportunities for physical independence, unsupervised recreation.”

Free play had been in retreat and technology on the march since the 1980s. But it took the invention of the smartphone to complete the mutation of childhood from “play-based” to “phone-based.” He writes, "… giving smartphones to young people en masse constitutes the largest uncontrolled experiment humanity has ever performed on its own children.”

While all this was happening, parents (who were hypnotized by their phones, too) were hearing about, and sometimes seeing at home, children succumbing to real distress—depression, anxiety, self-harm, even suicide.

Starting in about 2010, suicide rates for young adolescents in the U.S. shot up (increasing 91% for boys ages 10-14 and 167% for girls). The rate of self-injury almost tripled between 2010 and 2020.

Ironically, the creation of social media—with their promise of “connectedness”—has left young people lonelier and with fewer friends. For girls, the apps have proved toxic, Mr. Haidt writes: “Social media use does not just correlate with mental illness; it causes it …. The phone-based life produces spiritual degradation … in all of us."
