I think that social media will never work so long as people can post politics/news/drama/celebrity gossip in it. These are topics that NEVER run out of content. People engaged with it will never find peace and will never let others have peace.
I used to think it was only politics, but I visited a social media like Reddit that filtered politics by default--I forgot what it was called--and it still looked terrible because of all the drama.
It's a colossal waste of time. If you spend 20 hours learning Regex, that will help you for your lifetime. If you spend 20 hours talking about the latest disaster, in 20 hours that is all obsolete because there is a new disaster. And those 20 hours will make you angry and fill you with indignation while even gaming for 20 hours would have a more positive impact on you.
I'm not saying these things aren't important, but they are really not that important compared to how much of the Internet has become soaked with them.
