Justin Rosenstein had tweaked his laptops operating system to block Reddit, banned himself from Snapchat, which he compares to heroin, and imposed limits on his use of Facebook. He was particularly aware of the allure of Facebook likes, which he describes as bright dings of pseudo-pleasure that can be as hollow as they are seductive. And Rosenstein should know: he was the Facebook engineer who created the like button. There is growing concern that as well as addicting users, technology is contributing toward so-called continuous partial attention, severely limiting peoples ability to focus, and possibly lowering IQ. One recent study showed that the mere presence of smartphones damages cognitive capacity even when the device is turned off. But those concerns are trivial compared with the devastating impact upon the political system that some of Rosensteins peers believe can be attributed to the rise of social media and the attention-based market that drives it. Drawing a straight line between addiction to social media and political earthquakes like Brexit and the rise of Donald Trump, they contend that digital forces have completely upended the political system and, left unchecked, could even render democracy as we know it obsolete. It is revealing that many of these younger technologists are weaning themselves off their own products, sending their children to elite Silicon Valley schools where iPhones, iPads and even laptops are banned.
