Is it the end of the social media empire? Twitter is in disarray, with advertisers fleeing the network and users constantly refreshing their feeds to check if it still exists. The famous lettuce that beat Liz Truss has been put on the scene again, this time against the blue bird of Twitter. Facebook and its parent company appear to be inching toward the decline of the terminals: shares are down 70%, user growth has stalled, and the young people who feed the networks are leaving the platform. Empires seem to be tottering. “The story of its ruin is simple and obvious,” Edward Gibbon wrote of another empire, “and instead of asking why the Roman empire was destroyed, we should be surprised that it has lasted so long.” Gibbon wrote a six-volume treatise on the decline and fall of the Roman Empire, but his insights into its decline may well apply to the social media empires of Twitter and Facebook. “After diligent investigation,” he wrote, “I can discern four principal causes of Rome’s ruin: I. The injuries of time and nature. II. Hostile attacks by barbarians and Christians. III. The use and abuse of materials and IV the domestic disputes of the Romans. These four, I think, may well apply to the decline of the social media twins.
