An ex-Facebook boss has said social media is very harmful to our society. Chamath Palihapitiya joined Facebook in 2007. He was responsible for increasing Facebook's users. He is now very guilty about getting more people to use social media. He said the networks are destroying society. Twenty years ago, people talked to each other. Today, people message each other and do not talk. People worry too much about what others think of them. They post photos and wait to see how many people like the photo. They get sad if people do not like the photo.

Mr Palihapitiya said people should take a break from social media to experience real life. He wants people to value each other instead of valuing online "likes, and thumbs-up". Palihapitiya says fake news is affecting how we see the world. Large websites spread lies. It is also becoming easier to hurt other people online. Anyone can post lies about other people. Palihapitiya said this was a global problem. He has banned his children from using social media. However, he did say that Facebook was a good company. He said: "It's not all bad. Facebook overwhelmingly does good in the world."
