A former Facebook executive has said social media is doing great harm to society around the world. The executive is a man called Chamath Palihapitiya. He joined Facebook in 2007 and became a vice president. He was responsible for increasing the number of users Facebook had. Mr Palihapitiya said he feels very guilty about getting more people to use social networks. He said the networks are destroying society because they are changing people's behavior. Twenty years ago, people talked to each other face to face. Today, people message each other and do not talk. People also really care about what other people think of them. They post photos and wait to see how many people like the photo. They get very sad if people do not like the photo.
Mr Palihapitiya said people should take a long break from social media so they can experience real life. He wants people to value each other instead of valuing online "hearts, likes, and thumbs-up". Palihapitiya also points out how fake news is affecting how we see the world. It is becoming easier for large websites to spread lies. It is also becoming easier to hurt other people online. Anyone can hide behind a fake user name and post lies about other people. Palihapitiya said this was a global problem. He is worried about social media so much that he has banned his children from using it. However, he did state that Facebook was a good company. He said: "Of course, it's not all bad. Facebook overwhelmingly does good in the world."
