From instant messaging to endless social media feeds, cell phones have made almost everything in modern society more convenient. While they have allowed people thousands of miles apart to keep in touch at the tap of a button, that convenience has also become a double-edged sword. Constant phone use has become a destructive force. In his TEDTalk, Ambrosi presents a concerning statistic that the average 18-year-old is on pace to spend 93% of their remaining free time looking at a screen ; time that could be spent developing skills, or pursuing meaningful goals. By feeding our curiosity with endless streams of quick, shallow content—what Robertson might call intellectual junk food —people are sacrificing opportunities for self-improvement and living healthier lives. Reduced phone usage has immediate benefits as Zomorodi finds after a week-long social experiment: people who attempted to cut down their screen time reported feeling happier.
