I don't think you're wrong, but I'd just add that social media platforms like Facebook are doing everything they can to keep a user's attention at the cost of closer IRL relationships or anything else in their lives. To them, the more time you spend on their platform, the more money they make.

So increased social media use is definitely a symptom of broader disconnection in our societies, but it's also helping that disconnection along quite happily.
