I've known this facts that social media has it positive impact and it's negative impact also. @tarazkp but I will always maintain a stand that the positive impact is way more accommodating than the negativity.
Let me state some negativity that these social media indirectly prompted or promoted was the propaganda on sensitive information, information without fact check can be easily put out there and may cause uprising, the religious war and tribal sentiments cants just die down if there's no strict rule and enforcement laid down because someone in his room can just fabricate a lie and send to the public and it can cause a very serious tension. Same way the positivity of social media impacted human life better and faster than ever imagined. I just has it merits and demerits.
*Now for self discipline pertaining social media, the tender age needs parental guardians for proper indulgence to media. The kinds of message passed through the media destroy life's way easier than when social media wasn't in existence.
I think. *
I suspect that there are more negatives than positives, but the negatives people highlight are large, but the positives minimal. There are also many small negatives that stack up, compounding to make a massive amount of negative outcome, that people don't attribute directly to the platforms, but could.
