Chamath Palihapitiya is the latest former Facebook executive to call the company out, saying at a recent Stanford appearance: “I think we have created tools that are ripping apart the social fabric of how society works,” and expressing “tremendous guilt” for his participation. Palihapitiya certainly doesn't mince words: “The short-term, dopamine-driven feedback loops we’ve created are destroying how society works… No civil discourse, no cooperation; misinformation, mistruth. And it’s not an American problem — this is not about Russians ads. This is a global problem.” Palihapitiya, who rose to the position of vice president for user growth at Facebook, appears to have struck a nerve, since the company made the rare move of defending itself, saying “When Chamath was at Facebook we were focused on building new social media experiences and growing Facebook around the world. Facebook was a very different company back then and as we have grown we have realised how our responsibilities have grown too.” It's interesting that Facebook doesn’t deny Palihapitiya’s criticisms!
