In a room at the Emirates Towers, among journalists and content creators, sat a child with more than 400,000 followers. The occasion was a media briefing by the Ministry of Family and the Child Digital Safety Council, and the presence of underage influencers was itself a statement. Then two of them stood and asked the minister, Sana bint Mohammed Suhail, a question that cut to the heart of a global argument: why had the UAE banned children under fifteen from using social media platforms? The minister’s reply, delivered with the calm of someone citing settled science, was that the decision rested on extensive studies and wide consultation with national institutions and experts, and that the sole criterion was the best interest of the child.

That exchange captures a moment when the certainties of the past decade are being overturned. The UAE’s ban is part of a legislative wave. The United Kingdom and Australia have both moved to prohibit social media access for those under sixteen, with former British prime minister Keir Starmer framing it as a restoration of childhood. In Brazil, an unprecedented drop in the number of children under twelve who own a mobile phone has been recorded, driven by parental fears of robbery, exposure to inappropriate content, and the toll on mental health. A federal law restricting smartphone use in schools now reaches 92 per cent of basic education institutions, and school directors report sharp improvements in attention, engagement, and face-to-face socialising, alongside a marked decline in cyberbullying and anxiety.

The unease is not confined to direct use by children. A joint study by a cybersecurity firm and the Singapore Institute of Technology, drawing on responses from nine countries across Asia and the Middle East, found that even when a child has never touched a smartphone, social media platforms can assemble detailed “shadow profiles” from photos, videos, and tags posted by parents and relatives. Seventy-four per cent of parents surveyed were concerned that their children’s data was being used to train software; nearly as many believed platforms were actively profiling minors. Yet the practice of “sharenting” reveals a cultural split: exactly half of respondents felt a sense of camaraderie and affirmation when sharing family milestones online, while the other half did not. Meanwhile, a systematic review by researchers at several British universities has recommended that children under two receive no regular, intentional screen time at all, linking early exposure to reduced bonding, delayed language development, and a heightened risk of overstimulation. By the age of two, the researchers noted, daily screen use has become almost universal and routinely exceeds recommended limits.

In Australia, the push for regulation is colliding with the slow machinery of government and the complexities of free expression. A royal commission on antisemitism and social cohesion heard this month that a mandated digital duty of care for platforms—recommended in 2024—remains at least eighteen months away, delayed in part by an election and a change of minister. Jewish community representatives expressed frustration at the timeline, given the impact of online hate. At the same time, a separate debate is unfolding over proposals to force platforms to mitigate the risks of anonymous accounts, which are widely used for coordinated harassment but also provide a lifeline for domestic violence survivors and whistleblowers. The communications minister has insisted that users will not be forced to present government ID, but critics warn of a de facto digital identity system. A major newspaper’s editorial board cautioned that laws to curtail online bile must not come at the cost of legitimate anonymity claims.

The child’s question in Dubai hangs in the air. It was not a protest but a genuine inquiry, and the minister’s answer—that the ban was not a battle against technology but an attempt to restore balance to the most sensitive years of identity formation—was heard in a room where children were already public figures. The UAE’s bet, as one observer put it, is that a nation is not measured by the number of followers its children have, but by the depth of their character and the soundness of their awareness. That bet is now being placed, in different ways, from São Paulo schoolyards to the policy chambers of Canberra, as a generation’s digital childhood is redrawn not by a single law but by a slow, uncoordinated, and deeply personal recalibration of what it means to grow up.
