It's hard for me to understand. I have a friend who has kids who are in some ways smart, but unable to put down a smartphone, forming ADD, and reinforcing autism.
As I remember, there was a policy a few years back in P.R.China which restricted online activities for kids under a certain age. I think this was obsensibly linked to online gaming. Perhaps MMO games which I think have always been under some kind of restrictions, if seldom enforced, at least back in the days when there were internet bars.
Being more of the TV generation, the best I can do to rationalize the addictiveness of gaming or social media, is using analogies of cocaine or opium derivatives and synthetic derivatives. But I think even that is not nearly a good analogy.
I'm not sure what are the solutions to the divisions in the US, other than a sane leadership that values the meaning of life, liberty and love of itself. US policies affect more than just the US, so fair to say we all have a vested interest to see the US, the EU and other places adopting forward looking policy.
Sueing Tiktok might be rational, but I'm not sure whether the effect will be so helpful.
What would be a better remedy after money has changed hands. Investing that money into teaching kids how algorithms work, how they are employed in social media and how they might be affected by them. Even how they might use there own algos..
or just to keep sueing, and keep restricting the next social media platform, again and again? You gotta give kids a better alternative.
