After decades of immunity from liability, social-media platforms such as Meta and Snapchat may be vulnerable to a new bipartisan bill that seeks to curb damaging content on the Internet. But even if it passes, the law wouldn’t take effect until January 1, 2027, giving Big Tech plenty of time to bury Congress in lobbying money and political pressure. That’s why a new documentary, Can’t Look Away: The Case Against Social Media, matters now more than ever. The film follows the Social Media Victims Law Center, a scrappy group of non-white-shoe lawyers trying to help the parents of children who died buying fentanyl-laced stimulants on the Internet or who killed themselves over sex scams or an overload of suicide messaging. The stories of loss are affecting and scary. But the film also makes clear just how these sites use algorithms and other techniques to bombard vulnerable users with irresistible and inflammatory content. When misused, social media can be as lethal as cigarettes and guns, making Silicon Valley the Big Tobacco of our age. —Alessandra Stanley
