Meta's landmark settlement with nearly every US state promises curfews and time limits for teens on Instagram and Facebook -- but rests on age and parent checks nobody has figured out how to make work.

The deal, which ended a federal trial in Oakland, California, on Wednesday, gives Meta one year to identify which of its users are 13 to 17 years old.

Those accounts will have curfews and time limits switched on by default, and only parents will be allowed to loosen them.

How that gets enforced is unclear -- and any system Meta builds risks angering privacy advocates, who warn it hands platforms and governments yet another way to identify users, infringing on civil liberty.

For the new regime to work, Meta must determine the age of every user in the participating states and territories, adults included.

Methods could include identification documents, mandatory selfies, or analysis of user activity. Any account not verified within 14 days will face the same constraints as a teenager's.

These approaches have already faltered elsewhere.

Eight months after social networks were banned for under-16s in Australia, teen usage has climbed back almost to previous levels, thanks to virtual private networks, or VPNs, that conceal a user's real identity and location.

As for parents, the agreement offers no way to establish that a supervising adult is who they claim to be.

What would stop an older sibling from passing themselves off as a guardian, Judge Yvonne Gonzalez Rogers asked Wednesday as she weighed Meta's plans.

"There is some fluidity, very intentionally," said Nicklas Akers, a California prosecutor, who added that there was no plan to require a birth certificate or identification from the parent.

- Margin of error -

With no reliable way of verifying ages and parents, curfews and time limits remain theoretical.

"Teens are notorious for finding workarounds to these types of rules, and parents can also override some of the most stringent ones," said social media industry expert Jasmine Enberg.

"Looking ahead, that could take some of the responsibility away from Meta and put it on parents, with the goal of helping insulate the company from similar cases in the future," she added.

In France, where a ban on under-15s was just struck down by the Constitutional Council, many children get around the rules with their parents' help, according to the communications regulator Arcom.

If Meta cannot verify a user with identification, such as a driver's license or passport, it will estimate age by analyzing that user's activity -- collecting still more data in the process.

"This enshrines Meta's harmful surveillance into law, and it will compromise users' privacy and anonymity while increasing their exposure to data breaches and government data requests," the digital rights group Electronic Frontier Foundation said in a statement.

The settlement does include safeguards, limiting data collection to what age estimation requires and letting adults wrongly classified as minors appeal.

It is "the most significant intervention in children's online safety we have seen," said Iain Corby, head of the AVPA, an industry association for age-verification providers.

Identification documents carry their own risks. In October, a breach at a third-party age-verification company potentially exposed the government IDs of 70,000 Discord users.

- Improvising -

With no reliable or trusted methods available, everyone is improvising.

OpenAI applies a restricted version of ChatGPT to minors by guessing a person's age from their usage patterns, an approach Meta's settlement allows.

In the European Union, where the tracking of minors is tightly constrained, it has delayed the rollout for months.

France has sketched out a different path, in which a trusted third party verifies ages using the "double-blind system" already in place for adult sites.

The verifier does not know which site is asking, and the site gets only a binary answer: allowed or not.

Nothing like that exists in the United States, where Meta will run the checks itself -- and keep the data.

Huawei launched a new version of its flagship foldable smartphone on Monday as it seeks to defend its lead in the Chinese market for premium handsets against Apple and Xiaomi, both of which are also unveiling new products.

The new Mate XT2 folds out twice to open into a tablet-sized screen and ‌features Huawei's ‌new Kirin 9050 Pro chip.

Huawei ‌says ⁠the chip's design ⁠allows it to deliver more computing power while using less electricity, helping the company overcome US restrictions on access to advanced technology.

Xiaomi launches a rival foldable phone later on Monday, while Apple unveils its latest ⁠iPhone series on Wednesday, with expectations ‌high that it ‌too will be unveiling a foldable phone.

The Mate XT2 ‌features a redesigned folding mechanism, improved water ‌resistance as well as an optional screen that prevents people nearby from seeing what is displayed. It also has upgraded cameras and delivers ‌42% better overall performance than its predecessor, based on company tests.

Huawei, which ⁠does ⁠not sell in the US due to sanctions, leads China's smartphone market with a 22.6% share in the second quarter, ahead of Apple's 18.1%, according to consultancy IDC. Xiaomi has 12.4% of the market.

Huawei is even more dominant in folding phones, accounting for 68% of shipments in China in the second quarter, according to Smart Analytics Global, a US-based research company.

AI Data Centers Are Less Thirsty Now, Tech Giants Say

Data centers are running into a wall of public anger in the United States over their thirst for water and power.

The tech giants spending billions of dollars on them say the water part, at least, is solvable.

Data centers are the warehouses full of computer servers that run the internet and increasingly artificial intelligence.

The computers get hot, and keeping them cool takes water.

American chip giant Nvidia said in a June report that it can eliminate water consumption almost entirely at some facilities when deploying DSX, its newest system for designing and managing AI data centers.

It's a bold claim, and one the industry is under mounting pressure to make good on.

In 2025, data centers consumed 222 billion liters (59 billion gallons) of water worldwide for cooling, according to consultancy Rystad Energy.

Without adaptive measures, the figure could nearly triple to 644 billion liters by 2030, Rystad estimates. Steps to limit the growth could keep it under double.

Nvidia's new method uses a closed-loop cooling system in which liquid flows directly through the servers, as close as possible to the chips, whose temperature can rise above 80C (176F).

The problem is that "there's a pretty direct trade-off between how much water is used and how much energy is used" for temperature control, said Andy Masley, an independent researcher who covers AI and data centers.

Cutting back on water use usually means more power as the liquid in those sealed pipes still has to be cooled down somehow, usually by blowing air over it -- and that takes electricity.

Nvidia gets around some of this by letting the liquid enter the servers warmer than usual, at 45C.

Most other closed-loop systems ran at about 32C in 2024, according to the Uptime Institute, which certifies data centers.

By starting with warmer water, Nvidia does not need to pump in cooled air year-round.

"Simple fans circulating the air" are often enough, though sometimes a mix of methods is needed, said Josh Parker, Nvidia's head of sustainability.

At sites in extreme climates, or during a heatwave, chill airflow or water evaporation is still necessary.

- Public relations -

Microsoft, Amazon Web Services (AWS) and Meta told AFP that they also use closed-loop systems, which they said involve no net water loss.

The two cloud computing giants, which have been expanding their already huge data center footprints, used more water overall between 2022 and 2025, but their water use efficiency improved by 25 percent at Microsoft and 37 percent at AWS, according to their most recent sustainability reports.

There is no industry-wide consistency, however, in how companies report data on so-called environmental, social and governance (ESG) efforts.

Elon Musk's SpaceX, now a major player in data centers after it acquired his artificial intelligence company xAI, has never published an ESG report.

In June, ratings agency MSCI gave SpaceX its lowest ESG score.

"Because water is generally much cheaper than electricity," companies have less incentive to cut water use on cost grounds alone, said Shaolei Ren, an engineering professor at the University of California, Riverside.

"There are incentives," Ren said, but they have more to do with public relations amid the growing backlash to data centers across the United States.

Another obstacle is that upgrading an older data center to newer, less thirsty technology is expensive.

That may matter less than it sounds.

Older data centers are smaller and less powerful than the enormous new ones being built now, so they need less cooling in the first place, said Minh K. Le, who leads data center and hydrogen research at Rystad.

And the water a data center uses directly is only part of the story.

Water is used to generate the electricity that powers the data center, and to manufacture its chips and servers.

In the United States, that hidden water use can be twice the amount a data center consumes on its own.

At the World Humanoid Robot Games in China last month, robots jumped, boxed and danced. Some fleet-footed bots ran faster than Usain Bolt over 100 meters. Spectators cheered the machines’ improving capabilities and their meme-worthy stumbles.

Two days after the Games ended, the People's Liberation Army's official newspaper drew its own conclusions from the show. The PLA Daily called for researchers to accelerate the transfer of cutting-edge technologies from laboratories to military training grounds for robotic "combatants."

China's defense establishment is accelerating research into humanoids’ military uses and planning for their eventual wartime deployment, according to a Reuters review of more than 100 Chinese military procurement notices, academic studies, patents, official publications, government records and defense-company materials.

Military institutions are testing humanoids against battlefield requirements, seeking to acquire robots and technologies to train them, and studying how they might function alongside troops, the previously unreported records show. The work gained momentum in 2025 and 2026, focusing on robot perception, manipulation, and training data.

Chinese manufacturers accounted for about 95% of global humanoid shipments in 2025, according to BofA Global Research. That commercial dominance gives the PLA access to an expanding industry while developing its own military applications.

China’s robot defense research underscores how rapidly military technologies are evolving globally. In the Russia-Ukraine war, semiautonomous drones that use artificial intelligence for navigation and targeting have transformed reconnaissance and attack, while robots carry supplies and retrieve casualties. Reuters has previously documented the Chinese military’s efforts to learn from Europe’s deadliest conflict since World War II.

That evolution is driving worldwide military interest in autonomous systems.

"Going where we don’t want humans to go is one of the most compelling reasons to develop robots in the first place," said Dennis Hong, a professor of mechanical and aerospace engineering at UCLA. "If losing a robot means avoiding the loss of a human life, then the robot can become expendable."

China's defense ministry and the National University of Defense Technology (NUDT), the PLA’s premier research institution, ‌didn’t respond to requests ‌for comment about humanoid robots’ military applications.

Reuters found no evidence that China has deployed an armed humanoid with an operational PLA unit. The robots remain energy-intensive ‌and unreliable ⁠outside controlled demonstrations. Battlefield ⁠environments pose many variables and challenge robots’ abilities in unpredictable ways, said Aaron Johnson, a professor of mechanical engineering at Carnegie Mellon University.

URBAN ASSAULT FORCE

Already, China has a vision for humanoid robots in urban warfare.

Six "combat robots" – humanoids, robot dogs or unmanned vehicles – would be split up between two assault teams. Working with ground troops, the robots would clear an enemy-occupied building, floor-by-floor and room-by-room.

That scenario was described in an August 2025 paper by researchers at NUDT’s test center in Xi’an. The study modeled an urban assault force using equipment the authors projected could be available within five to 10 years. It didn’t specify the robots’ rules of engagement, the weapons they would carry, nor how they would handle civilian encounters.

Improvements in balance, perception and endurance could make humanoids useful in places including buildings, tunnels and ship interiors, said Juo-Min Chou, a researcher at Taiwan's Institute for National Defense and Security Research. "Their two hands and two feet could, in theory, combine mobility, climbing and manipulation," she said.

For simpler reconnaissance or logistics missions, however, quadruped, tracked or wheeled robots would generally be cheaper and easier to deploy at scale, Chou added.

Chinese military commentary envisions an expanding range of roles for humanoids. A July 2025 article in PLA Daily argued that humanoid ⁠missions could eventually evolve "from supporting combat toward primary combat" and discussed how robots might be authorized to fire on a living target that had been verified ‌by a human.

In December, the PLA Eastern Theater Command released an AI-generated montage that showed military robots, including humanoids and quadrupeds, overwhelming Taiwan's defenses in a hypothetical ‌future conflict.

China isn’t alone in exploring battlefield uses for humanoids. Last year, the US Army launched a competition to develop "militarized humanoid capabilities" that could eventually work alongside soldiers. The Army said potential roles included reconnaissance, security, obstacle clearing, hazardous-material operations and offensive ‌and defensive missions in urban terrain.

Up to 10 finalists were due to test their systems with US military experts this year, with as much as $1.25 million available for follow-on contracts.

The US robotics industry, however, trails ‌far behind China in developing two-legged and four-legged machines. Reuters reported last month that China’s Unitree robots – among the world’s leading producers of humanoids and quadrupeds – based designs for its best-selling robot dogs on innovations financed by the US military.

The Pentagon and the US Army didn’t comment for this story.

INFILTRATING ENEMY LINES

Chinese interest in humanoid robots’ military applications began to pick up in 2024. That year, NUDT and China’s Academy of Military Sciences hosted a defense-technology forum that included a session on military applications for humanoid systems, according to NUDT’s website. Neither institution responded to Reuters’ questions.

A year later, NUDT explicitly framed humanoid robots as battlefield tools. A university competition in June 2025 featured an event that simulated "infiltration behind enemy lines," requiring robots to enter an area, map it and locate targets, ‌according to its website. Another envisioned robots conducting identity checks, discipline inspections and security patrols at military bases.

The military-research university described the competition in part as a proving ground for humanoids to eventually "move toward the battlefield."

Procurement records around that time reflected that ultimate goal.

In May 2025, the PLA issued a tender to ⁠purchase a humanoid robot, including installation and technical training. Four months ⁠later, a procurement notice that listed an NUDT email as its contact address sought an "embodied humanoid robot intelligent perception and dexterous operation system."

The records contained few specifics. Reuters couldn’t determine whether the tenders were filled, and if so, which companies won or which robot models were supplied.

In June this year, the PLA budgeted about $300,000 for a system to collect and label camera, radar and motion data for humanoids, including information about terrain they could traverse, according to another military procurement document.

The specifications show Chinese military interest is extending from robot bodies into the perception, manipulation and training systems that defense scholars say are essential for humanoids to move beyond controlled demonstrations.

REMOTE OPERATION

By 2026, humanoid development had spread beyond military academia into China's defense industry.

The Fuxi robot made by Norinco, a state-owned defense conglomerate, is one example. Company materials published in August described the full-size humanoid as capable of sentry duty, all-weather reconnaissance, intelligent patrol and fulfilling dangerous roles.

Fuxi can be paired with Norinco’s teleoperation system, which allows a human operator to control a humanoid remotely, according to the company. Removing the need for a robot to make all decisions autonomously would address what many robotics experts say is the biggest challenge with humanoids.

Norinco didn’t respond to a request for comment.

Malcolm Davis, a senior analyst at the Australian Strategic Policy Institute, said he didn’t see humanoid robots as practical battlefield systems at present. "But in five to 10 years," he said, "they could very well be."

Even if remotely operated today, humanoid systems designed for autonomous deployment would eventually need to navigate ethical dilemmas. The laws of war require forces to distinguish combatants from civilians and to refrain from attacking wounded or surrendering fighters.

The International Committee of the Red Cross has cautioned that autonomous weapons may struggle to interpret signs of surrender reliably because such judgments can depend on context, conduct and intent.

The US military requires autonomous weapons to undergo legal review and realistic testing and for commanders and operators to exercise appropriate judgment over the use of force. China’s defense ministry said in March that AI-powered weapons should remain under human control.

Those concerns haven’t deterred China's exploration of humanoids’ military uses.

Wang Yonghua, a researcher at China’s Academy of Military Sciences, wrote in a November commentary that humanoids face unresolved problems in movement, perception and intelligence. Technical breakthroughs, lower manufacturing costs and industrial-scale production would be needed for humanoids to become widespread military systems.

If those conditions are met, Wang wrote, "humanoid robots will stream onto the battlefield."
