Nobody has mentioned the tens, if not hundreds of millions of dollars that the major platforms have spent to take advantage of and manipulate people on psychological positioning. Get them interested, get them addicted, manipulate algorithms to prey on people to make them spend more time and give these platforms more importance and influence against the well being of it's users, especially those with minds that have not fully developed that individually, some people can't cope with.
Sure, for the majority of people, it's not much of a concern and I don't personally have any issues with them, but I've seen first hand how people born with social media influencing their every thought and action have been detrimental to their developing minds. All you need to do is notice the growing cultural divide and toxicity that has come from all this. So much division and hatred, but it's not just social media anymore, though it's influence has shaped how mainstream media and people's perception of one another have changed.
The only real solution would be to prevent people access until they've reached the developmental capacity and to teach people how to spot and avoid becoming part of these trappings. It's probably too late to expect any paradigm shift but the future isn't looking great no matter which political, socioeconomic, ethic, or other group you fall into, belong or identify with. People are mostly falling into this re-segregation without even realizing this. We're all humans, everyone isn't perfect, many people who have suffered neglect, abuse and face other personal adversities may need more help than others, but the hate, division and self-absorption are now too strong. It doesn't cost anything to be nice, but there are fewer and fewer people who would care.
