Funny how quickly "won't someone think of the children" turns into mandatory government ID for private services, banning necessary and secure (and encrypted) communications systems, and locking children out of access to the de facto communication systems of the modern era.
This is a privacy nightmare on all fronts and a horrible limit on freedom of speech. These kids will be learning how to drive a car, yet unable to contact their extended family over Messenger or follow news on Twitter. For everyone else, it means no anonymity or secrecy which has a chilling effect on free speech at a time when fascism is growing within democratic countries and dissidents are being imprisoned or murdered.
Yes, there are some really big problems with social media, but keeping children away from it doesn't fix the problems - it just leaves them for the rest of us to deal with. Let's fix the root of the problem, starting with the recommendation algorithms that inherently polarize people by building echo chambers around them and pushing divisive content all in the name of "engagement".
That's because the tech industry never made any attempt. It's like you blocked all the good options, now you get the worst one because it's one you can't block.
