“Can we go back to using Facebook for what it was originally for - looking up exes to see how fat they got?” (Bill Maher)

Recently, Apple CEO Tim Cook made a name for himself when he spoke out in favour of restricting the use of technology in schools, suggesting that he had banned his nephew from participating in social networks. And Sean Parker, co-founder of Napster and long-time Facebook consultant, is quoted as saying,"God only knows what it's doing to our children's brains". Social media has a problem, and not just since Facebook's inglorious role in the American election campaign. Platforms whose self-declared goal it is to bring us all closer together and make us happy seem - indeed - to have the opposite effect.
