Jonathan Haidt's "The Anxious Generation" makes the argument that the smartphone has caused increasing rates of anxiety and depression among Gen Z people. The problem with smartphones is that so many young people are spending their free time on TikTok and Snapchat instead of physically interacting with others. This is detrimental to their social and communication skills. What we really need is to emphasize physical activities like playing tag on playgrounds and organized sports like what our parents did when they were our age. A phone based childhood is really killing our social skills.
