Now it's very logical to spin that expensive infrastructure down, removing free communication channels which can dangerously synchronize people against the state, and leaving only channels of control: digital ID, CDBC and a white list of governmental "services", all else outlawed.
People of 2010s uploaded their personal data into the cloud because they thought that was cool, people of 2030s will do because their telescreens demand them so.
Everyone who thinks this will stop at "think about the children" is beyond all repair.
"Think of the children" is weaponized for censorious purposes, but also the harms of social media are well documented (unlike many of the other moral panics fuelled by this phrase). Communication channels are becoming managed spaces, but by private companies not accountable to the electorate, not by the state.
I'm not sure a blanket under-16s ban on all social media is the right answer, but there are really good reasons why people support this that you need to engage with to have a useful discussion here.
Remember how YouTube and Netflix used to let you rate things on 1-5 stars? That disappeared in favor of a simple up/down vote.
Most services are driven by two metrics: consumption time and paid subscriptions. How much you enjoy consuming something does not directly impact those metrics. The providers realized the real goal is to find the minimum possibly thing you will consume and then serve you everything above that line.
Trying to find the closest match possible was actually the wrong goal, it pushed you to rank things and set standards for yourself. The best thing for them was for you to focus on simple binary decisions rather than curating the best experience.
They are better off having you begrudgingly consume 3 things rather than excited consuming 2.
The algorithmic suggestion model is to find the cutoff line of what you're willing to consume and then surface everything above that line ranked on how likely you are to actually push the consume button, rather than on how much you'll enjoy it. The majority of which (due to the nature of a bell curve) is barely above that line.
If e.g. retention correlates to watch time (or some other metric like "diversity of content enageged with"), then you will optimize for the short list of metrics that show high correlation. The incentive to have a top-tier experience that gets the customer what they want and then back off the platform is not aligned with the goal of maintaining subscription revenue.
You want them to watch the next thing, not the best thing.
