It&#x27;s already happening.<p>Recently, I&#x27;ve asked my high school aged sister and colleged aged brother about how many of their friends and peers use FB nowadays.<p>Brother -- He and his friends uses it sometimes. But most of their social activities are shared on Instagram or Snapchat and occasionally twitter.<p>Sister -- Barely at all. FB is seen as uncool and old school by her and her friends. She and most of her friends share their social activities on instagram and snapchat.<p>Ironically, my mom (in her 50&#x27;s) uses FB fairly regularly, both for sharing updates and checking up on her friends&#x2F;acquaintance.
