When the Mexica people left their ancestral land of Aztlán in search of a new home, they were following orders from the sun god Huitzilopochtli. In 1325, the god’s prophecy brought them to a salty swamp at the lowest dip of the Valley of Mexico. “Among the reeds and bushes they spotted an eagle perched on a cactus devouring a snake,” writes the poet Homero Aridjis. “This was the sign they were looking for, and there, among the salt and sweet water lagoons, their priests took possession of the place with a ritual immersion in the waters.”

By the arrival of Hernán Cortés in 1520, the floating city they’d built in the marshlands of Lake Texcoco had boomed to a population of 200,000—larger than the Old World capitals of Lisbon or Paris. The city of Tenochtitlan grew through a complex system of artificial islands unlike anything the Spanish had seen, a feat of hydraulic engineering pioneered by Nezahualcóyotl, the city’s philosopher king.

Five centuries later, this lake system has nearly vanished—drained by colonists who razed Tenochtitlan, tapped its tributaries for farms, and paved its lake bed to build the second largest metropolis in the Americas: Mexico City, home to more than 21 million.

Today, Lake Texcoco has lost more than 95% of its historic expanse. It faced extinction when the $13 billion Nuevo Aeropuerto Internacional de la Ciudad de México (NAICM) began construction in 2015 on its desiccated bed. Building an airport there would have required expanding the gargantuan system of pipes, pumps, and canals that had already buried the valley’s lakes and rivers. Instead, Texcoco’s deserted ex-lake has become home to an immense ecological experiment close to the heart of Mexico City.

Weeks after President Andrés Manuel López Obrador took office in 2018, the combative leftist leader enraged international investors and Mexico’s business community by canceling the airport, which was already around one-third complete. During his campaign, López Obrador had railed against the project’s management for overspending and corruption. Then, in a post-election referendum launched by López Obrador’s party, the public had voted to scrap it (though critics claimed the results were unrepresentative, with just one in 90 Mexican voters casting a vote).

Left behind was an eerily empty landscape bigger than Paris, circled by the sprawl of Greater Mexico City. In this vast footprint, the president decreed, the city would build one of the world’s biggest urban parks, a project he dubbed a “new Tenochtitlan.” To oversee what would become known as Lake Texcoco Ecological Park (PELT), he appointed Iñaki Echeverria, a Mexican architect and landscape designer who had spent over two decades advocating for the site’s restoration.

Echeverria’s vision for the park is part of a wave of projects that have upended the traditional goal of ecosystem restoration: returning ecosystems to the state they were in before humans damaged them. Instead of seeking to roll back the clock, Echeverria is creating an artificial wetland that aims to transform the future of the entire Valley region, drawing lessons from both Tenochtitlan and modern Mexico City on how thriving cities can coexist with flourishing ecosystems.

With a budget of $1 billion, Texcoco Park is repurposing the structural skeletons and concrete gorges left behind by the airport construction to create artificial lakes and habitats intended to host human visitors and an unprecedented mix of species. And Echeverria’s team hopes the park can also help foster economic development by developing native plant nurseries and reviving cultural practices facing extinction, including the harvest of spirulina algae. While the end result would look little like Texcoco’s past, it could revive something more fundamental: the Valley of Mexico’s long-dormant history of building in step with natural systems.

Yet today, miles of Texcoco Park remain ringed by a perimeter fence, manned by guards in military uniforms. As the project races toward 2024, when López Obrador’s term ends (he’s vowed not to seek a second one), much remains inaccessible to the public and besieged by controversy. The plans for Lake Texcoco’s rebirth could yet vanish.

Lake Texcoco returns

Edged by mountain ranges and two volcanoes, the Valley of Mexico has historically formed an “endorheic basin,” where water cannot flow out but instead diffuses into the ground. This process concentrates salt at the lowest spot, where Lake Texcoco sits—the plug in the Valley’s bathtub. Through history, the area’s mixed salty and fresh waters have served as a petri dish for the evolution of unusual organisms, including an entire ecosystem of now-extinct fish species and the axolotl, an amphibian with the ability to regenerate limbs, named for one of the Mexica’s gods.

Today, the Valley’s environment bears the marks of destructive

Finding value in generative AI for financial services

UBS report cover

With tools such as ChatGPT, DALLE-2, and CodeStarter, generative AI has captured the public imagination in 2023. Unlike past technologies that have come and gone—think metaverse—this latest one looks set to stay. OpenAI’s chatbot, ChatGPT, is perhaps the best-known generative AI tool. It reached 100 million monthly active users in just two months after launch, surpassing even TikTok and Instagram in adoption speed, becoming the fastest-growing consumer application in history.

UBS report cover 1

According to a McKinsey report, generative AI could add $2.6 trillion to $4.4 trillion annually in value to the global economy. The banking industry was highlighted as among sectors that could see the biggest impact (as a percentage of their revenues) from generative AI. The technology “could deliver value equal to an additional $200 billion to $340 billion annually if the use cases were fully implemented,” says the report.

For businesses from every sector, the current challenge is to separate the hype that accompanies any new technology from the real and lasting value it may bring. This is a pressing issue for firms in financial services. The industry’s already extensive—and growing—use of digital tools makes it particularly likely to be affected by technology advances. This MIT Technology Review Insights report examines the early impact of generative AI within the financial sector, where it is starting to be applied, and the barriers that need to be overcome in the long run for its successful deployment.

DOWNLOAD THE REPORT

The main findings of this report are as follows:

Corporate deployment of generative AI in financial services is still largely nascent. The most active use cases revolve around cutting costs by freeing employees from low-value, repetitive work. Companies have begun deploying generative AI tools to automate time-consuming, tedious jobs, which previously required humans to assess unstructured information.

There is extensive experimentation on potentially more disruptive tools, but signs of commercial deployment remain rare. Academics and banks are examining how generative AI could help in impactful areas including asset selection, improved simulations, and better understanding of asset correlation and tail risk—the probability that the asset performs far below or far above its average past performance. So far, however, a range of practical and regulatory challenges are impeding their commercial use.Legacy technology and talent shortages may slow adoption of generative AI tools, but only temporarily. Many financial services companies, especially large banks and insurers, still have substantial, aging information technology and data structures, potentially unfit for the use of modern applications. In recent years, however, the problem has eased with widespread digitalization and may continue to do so. As is the case with any new technology, talent with expertise specifically in generative AI is in short supply across the economy. For now, financial services companies appear to be training staff rather than bidding to recruit from a sparse specialist pool. That said, the difficulty in finding AI talent is already starting to ebb, a process that would mirror those seen with the rise of cloud and other new technologies.

More difficult to overcome may be weaknesses in the technology

The Download: unpacking OpenAI Q* hype, and X’s financial woes

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Unpacking the hype around OpenAI’s rumored new Q* model

Ever since last week’s dramatic events at OpenAI, the rumor mill has been in overdrive about why the company’s board tried to oust CEO Sam Altman.

While we still don’t know all the details, there have been reports that researchers at OpenAI had made a “breakthrough” in AI that alarmed staff members. The claim is that they came up with a new way to make powerful AI systems and had created a new model, called Q* (pronounced Q star), that was able to perform grade-school level math.

Some at OpenAI reportedly believe this could be a breakthrough in the company’s quest to build artificial general intelligence, a much-hyped concept of an AI system that is smarter than humans.

So what’s actually going on? And why is grade-school math such a big deal? Our senior AI reporter Melissa Heikkilä called some experts to find out how big of a deal any such breakthrough would really be. Here’s what they had to say.

The Download: OpenAI’s wild year, and tech’s cult of personality

This is today’s edition of The Download our weekday newsletter that provides a daily dose of what’s going on in the world of technology.

Inside OpenAI’s wild year

Few companies can say they’ve had more of a rollercoaster year than OpenAI. At the beginning of 2023, the world’s hottest AI startup was riding high on the success of its ChatGPT chatbot. Now, it’s dusting itself off from an attempted coup which saw Sam Altman ousted and reinstated as the company’s CEO within a few short days.

Our AI experts have been following OpenAI’s every move throughout the year, often with exclusive access to the people building the revolutionary products and systems. Check out just some of the highlights from the past year—and what we think is coming next.

+ ChatGPT is everywhere. Here’s where it came from. While ChatGPT may have looked like an overnight sensation, it was actually built on decades of research.

+ Back in April, our senior AI editor Will Douglas Heaven had exclusive conversations with four OpenAI insiders to learn more about how they built the viral chatbot.

+ One of the year’s hottest topics was how ChatGPT was already changing education—from cutting corners for science homework, to writing entire theses. But some teachers believe that generative AI could actually make learning better. (Bonus: check out high school senior Rohan Mehta’s robust defense of ChatGPT in the classroom)

+ OpenAI’s hunger for data is coming back to bite it. The company’s AI services may be breaking data protection laws, and there is no resolution in sight. Read the full story.

+ Ilya Sutskever, OpenAI’s chief scientist, was one of the key executives to turn against and try to overthrow CEO Sam Altman in the recent OpenAI revolt. When Will Douglas Heaven met him earlier this year, Sutskever told him about his new priority—figuring out how to stop an artificial superintelligence from going rogue. Read the full story.
