Australian police are working on an AI prototype that will help them decipher Gen Z slang and emoji-laden messages written by online predators, a top official said Wednesday.

Australian Federal Police Commissioner Krissy Barrett said social media had become a breeding ground for bullying, sexual exploitation and radicalization.

Police were working with software giant Microsoft to develop a tool that would unravel sinister messages hidden by seemingly innocuous emojis and slang, she said.

“Clever AFP members, with Microsoft, are developing a prototype AI tool that will interpret emojis and Gen Z-and-Alpha slang in encrypted communications.

“This prototype aims to make it quicker for our teams to save children from harm much earlier.”

Barrett also warned about the rise of so-called “crimefluencers”—online predators who used their social media savvy to target young and vulnerable users.

“They are crimefluencers, and they are motivated by anarchy and hurting others, with most of their victims pre-teen or teenage girls,” she said.

Australia will from December 10 force social media platforms such as Facebook, Instagram and TikTok to remove users under the age of 16.

There is keen interest in whether Australia’s sweeping restrictions can work, as regulators around the globe wrestle with the dangers of social media.

The story of the park begins in 2014, when Enrique Peña Nieto, the president of Mexico at the time, announced plans for a new transport hub for Mexico City. It would be built on the largely dry bed of Lake Texcoco, the body of water that had once surrounded Mexico City’s ancient ancestor, Tenochtitlán, the center of the Aztec empire. The marketing promise was that NAICM would be one of the greenest airports in the world. The terminal, designed by Norman Foster—winner of the Pritzker Prize in 1999 and the Prince of Asturias Award for the Arts in 2009—was going to be the first to obtain LEED platinum certification, the highest international recognition for energy efficiency and sustainable design.

Its site, Lake Texcoco, had already lost more than 95 percent of its original surface area, and in 2015 plans were made to drain it completely to build the airport. However, when Andrés Manuel López Obrador took office as Mexico’s president in 2018, he canceled the plan. It would end up costing more than $13 billion and would leave behind serious environmental damage: The incomplete project destroyed a key refuge for migratory birds; carved up mountains in the State of Mexico (the federal region that surrounds Mexico City); razed agricultural land; and altered the landscape of the cultural capital of the Nahua, an indigenous people that includes the Mexica (or Aztecs).

Echeverría, who says he has been obsessed with the area for nearly three decades, was appointed by the new government to restore the local ecosystem. “It felt like I was stepping onto Mars,” says the architect, reflecting on being placed at the helm of the project. The park covers an area equivalent to 21 times the area of Mexico City’s enormous Bosque de Chapultepec park. Echeverría offers his own comparisons: “This place is three times the size of the city of Oaxaca and, as a reference for those outside Mexico, it’s roughly three times the size of Manhattan.”

The restoration project wasn’t a mere whim of Mexico’s new president, but the culmination of a century of visions and plans. “We’ve been skating around this for 75 years,” Echeverría says, citing restoration projects that were proposed as early as 1913, including ones by Miguel Ángel de Quevedo (a celebrated early environmentalist) in the 1930s and agronomist Gonzalo Blanco Macías in the 1950s. What was missing, Echeverría says, “wasn’t a lack of ideas, but of political will.”

Whether you’re worried about the open network at your local coffee shop or want to get around geo-restrictions when you’re traveling, NordVPN can help. A virtual private network (VPN) is like a protective tunnel, keeping your data safe from prying eyes. VPNs aren’t perfect protection (you need to trust your VPN provider), but they’re always going to be better than nothing when you’re using a public hotspot. They also make it easy to continue to watch your favorite shows even when you’re on vacation. If you want to learn more about how to protect yourself online, see our guide to The Best VPNs.
