I'm curious, what do you think is the solution for video game addiction? Because, I don't see any other way to tackle it other than limiting game time. My uncle deliberately gave his son an old phone, which doesn't have WIFI connectivity and games, to prevent him from getting a video game addiction. The kid is a lot younger than me, but is more smarter and talented than me, meanwhile I spent a good portion of my childhood playing video games and failing or barely passing classes, except in ones I'm interested in.
Video games have a therapeutic benefit, but often kids don't have the self-control and haven't learned how to time management yet. Which ends up with them overplaying, developing into habit, then turned into a video game addiction. Sure, that parents can be blamed, but most of them are busy these days with work, and have no time or the mental fortitude to keep looking after their children. So why not put limits on it, but I do agree the time shouldn't be decided by the government, should instead make it mandatory for parental guidance settings be installed into games, for them to control the limit on their own.
Getting really off topic and several posts in now so last post on this just to share my opinion and answer you. I think the more you restrict something to young people/children, the more they feel an inclination toward it and potentially abuse it. Of course this doesn't mean the reverse isn't true. Giving free rein almost certainly translates to losing the average and a net loss compared to your strategy. But here's where really good moderation and leadership shows up. China brute forces its way through a lot of problems. It honestly lacks a lot of finesse in politics.
Maybe the Chinese government is actually right in taking this move. The cost of not doing it could be much worse than doing it. My earlier point was a general expression of doubt on that method and restricting industry is a step I think is a little too far ... in my opinion and I'm probably wrong. Let's just remember that many eventually worthwhile things develop from things that were considered "a waste of time". The main issue I have with this is mostly the restricting China's industries. I think there is enough room for all of that and good stuff
could come out of the Tik Toks of the tech world.
As for the conversation on how to limit gaming if that's the desire, it's my opinion that Chinese parenting culture places a bit too much emphasis on the "learning is hard and uncomfortable" kind of attitude where kids need to be forced otherwise they won't do. This is true to an extent and probably why China's so much better than average. Where it fails is this method often extinguishing a genuine love for learning and restricting the outlier genius by placing undue force on them during important formative years. It could even be later than that and the overall more forceful nature of how the society is can limit individuals because they are pressured away from what they might be exceptional at, and more towards whatever makes them more money, is a more stable career, or is just preferred by whatever - their parents, the gov, friends, wives, husbands etc. Plus the whole rote learning + academic achievement culture, while nowhere near as caricatured as some western people make it out to be for China, it does often produce children and people who are a little too focused on only a few things; grades, university, career, income. It doesn't really focus on actually producing real academics, real intellectuals, and really talented people in their preferred and naturally gifted ways.
The evidence for my opinion is in the per capita measures of IP, papers, citations etc. While China's nominally excellent, it ought to be because of sheer size and it's relatively developed now. It still falls far short compared to the fully developed and industrialised nations when it absolute should be comparable (since they all are once a certain level is reached). Most of these nations don't push their kids as hard, don't limit their gaming and don't micromanage their paths and choices. Yet they produce far more per capita.
China's strategy seems to be to lift the average performance and agreeableness higher. The sheer number of genius level would be comparable even with stifling policies (assumed here). Overall win. Western strategy seems to be, almost everyone sucks and the average is really shit but the groundbreakers are allowed free rein to maximise their abilities. The society is pulled up by the very top tier whereas China wants the society to travel up together with a top tier that's comparable in size only due to sheer population. I suppose that's a safer bet indeed but it's certainly much less "romantic" and adventurous or daring. Same as the whole "hold America's ass to cross the river" sort of attitude. lol.
