You're right. But I think it's more than just about being an introvert or extrovert. In the past, boredome created a reason for most people to visit someone, play cards, host friends, or go somewhere. At present, more and more people (introverts and extroverts) are already turning to social media, streaming, gaming, YouTube, and any other online platforms as these offer modern, instant, unlimited entertainment with almost no coordination or planning.
