Former technology industry leaders are calling for urgent measures to protect children from smartphone addiction. Among those urging major changes is Tristan Harris, a former high-level employee at Google. He just launched a group that will seek to gather and publish evidence of how digital devices and social media can harm children and young people. Leaders of the organization, called the Center for Humane Technology, used to work for major technology companies. They hope to use this knowledge and experience to lead a “cultural awakening” among the public about the dangers of technology.
