Across Europe, the USA, the UK, Australia, and elsewhere, it is expanding into social media, messaging, gaming, search, and other mainstream services.The real question is no longer whether age checks will spread. It is what kind of internet they are turning into.The common framing says these systems exist to protect children. That concern is real.
