Just imagining world few centuries ago with instant social media is incredibly scary. When Science was not the first thing one could have thought about, people did not know what meant being on a planet. One took birth to fight wars and the cycle of war economy with dynasties, kingdoms, ambitions, rule. In the backdrop of constant war socio economic conditions, social media would have been only weaponised depending on who owned. With its feature of reach, speed, subtlelity, it would have been only a question of who was more smart to make it unnoticeable and tech knowledge to build an empire. One might argue that it could have solved problems sooner in those days but that is questionable even today. Ideas with good intention and direction become a unsolvable mess once outside interests start mixing with them.
