The highway with the most lanes in the world is in China and has 50 lanes, except for one small detail: it is a lie

by

Demographic growth, urban development and the great automobile boom crossed paths in the 20th century to give rise to some of the most spectacular roads today: from the Panamericana that has never closed to the road with the longest straight line in the world. Logic leads us to think: if there are more cars, then more lanes are needed to avoid traffic jams (spoiler: from one point on, not working). And if we talk about roads with more lanes, there is one place that takes the cake: the Interstate 10 in the United States. The point that interests us in question is in Houston, Texas: there an ordinary six-lane highway from the 60s became thanks to an astronomical widening of the widest road on the planet. It is this American highway that holds the record with 26 lanes and not a chinese highwaydespite the fame of the 50 lanes of the G4 Beijing-Hong Kong-Macao. The highway with the most lanes is in Texas. Within that highway that crosses the United States from Santa Monica in California to Jacksonville in Florida with a route of 2,460 kilometers in total length there is a specific section known colloquially as the Katy Freeway: a segment about 37 kilometers west of Houston. At its widest point, at Gessner Road, the road has 26 lanes in total: 12 main lanes (six in each direction), 8 service lanes (four in each direction) and 6 central dynamic toll lanes. This corridor is the backbone of mobility for the entire west of Houston, one of the largest cities in the United States and extremely dependent on the automobile (even for the United States): it has hardly any public transportation, little urban planning and decades of peripheral expansion. In this scenario, the I-10 is more than a highway: it is the artery of mobility and business parks, logistics centers, hospitals and universities that depend on private vehicles are concentrated around it. An unofficial record, not official. The Katy Freeway holds this record in practice, but it is not official (there is no Guinness for this) because no one has agreed on how to count the lanes. Do you only count those on the main road? There are 14. Do you add the side service lanes and the center toll lanes? You reach 26. Without a single, agreed upon criterion, Guinness cannot set a number and certify it. Brief history of its construction and expansion. The Katy Freeway was built in the 1960s and had six to eight lanes, sufficient for the mobility needs of the time. But between the 80s and 90s, Houston suffered spectacular urban growth: in 2000, traffic surpassed the 200,000 vehicles when had been designed for 120,000. In 2004, the American Highway Users Alliance (AHUA) classified it as the second most serious bottleneck in the country: they estimated that drivers lost 25 million hours a year. So the Administration planned a huge road expansion: an investment of 2.8 billion dollars and a four-year project between 2004 and 2008 to incorporate dynamic toll lanes inside an interstate highway for the first time. To make room they demolished an old railway corridor. As a curiosity, in 2014 there was another small expansion to add an auxiliary lane in each direction. Travel time from Pin Oak to downtown. Source: City Observatory / data: Houston Transtar More lanes and more traffic jams. Since a picture says a thousand words, above these lines is a graph from the non-profit organization City Observatory with data from Houston’s official traffic agency. City Observatory collects Although the AHUA described in a report that this expansion was one of the great success stories of traffic engineering to alleviate traffic jams and traffic jams, this was not the case: the congestion got worse. Just two years later, they recorded that travel times on that 47-kilometer route from the outskirts to downtown Houston increased by 13 minutes in the morning rush hour and 19 minutes in the afternoon. This phenomenon has a name: induced demand. Thoroughly developed by Gilles Duranton and Matthew Turner in “The Fundamental Law of Road Congestion: Evidence from US Cities“, offers a clear conclusion: vehicle kilometers traveled increase proportionally to the available lanes and the new roads attract more drivers and more trips until the added capacity is saturated. The G4 toll, seen in Street View What happens with the G4 Beijing-Hong Kong-Macao. It is common to find references to the G4 as “the 50-lane highway” thus overtaking the Katy Freeway on the right. The reality is another story: as verified by Africa Check with Google Mapsthe G4 is in practice a four-lane highway along almost its entire length of more than 2,000 kilometers. The expansion to dozens of lanes that usually appears corresponds exclusively to the Zhuozhou toll area (can be verified with Street View), near Beijing, where the number of lanes is expanded punctually to distribute the flow to the toll booths. Just half a kilometer later, it is reduced to four again. In 2015 there was a terrible traffic jam during the week of China’s National Day at that point that caused kilometer-long queues and the spread of that supposed “50-lane highway” when in reality it is the toll infrastructure of an ordinary four-lane road.

That bug has been waiting for its moment in Spain for 60 years. And your time is now

by

In 1964, someone decided it was a good idea to release a handful of estrildas in Portugal. Before the end of the decade, this small opportunistic bird from sub-Saharan Africa had already settled in Extremadura and Andalusia. By the 80s, it had already reached the east of the peninsula. For 60 years, estrildas had remained in a discreet background. It had taken root, but they weren’t getting traction. However, that has begun to change: in the last 15 years, Valencian estrilds have multiplied by 10 and in Catalonia the population has tripled. AND, to the surprise of the expertsthe key to the boom has been two other invasive species. What has happened? In recent days, several media have begun to publish reports announcing that the African bird “has already arrived” in Spain. However, the common estrilda has been here for decades. What is new is not that: what is new is that in recent years the proliferation of uncultivated plots (one in five are) is becoming the perfect breeding ground for two other exotic species, the common reed and the Pampa duster. And those species make the perfect habitat for estrildas. Do they eat them? No no. That’s why I say it’s curious: the researchers they have realized that it is not that birds consume these plants. The plants provide shelter, roosting sites and perfect structures for this species. The strilas have been surviving for years in a very hostile territory, now they have found some areas that suit them like a glove. The story, as you can see, is more complex. Above all, because it has an agricultural substrate. Without the profound changes of recent years in the countryside, neither the Pampa duster nor the common sugarcane would have reached where they have. In this sense, what is truly worrying is not the estrilda (a bird that, as far as we know, is not affecting the local fauna either). What has experts worried is the chain of invasions. You just have to think about it a little to understand: the feather duster is South American, the common reed is Asian, and the estrilda is African. Together, they have managed to become strong in southern Europe. Fauna and flora have logics that we are still unable to understand in depth. In the end, the key is always in the same place: that there is a moment when we are going to have to assume that the only way to get out of all the problems we are creating is to start comprehensively managing the field.

The superapp model that dominates in China never caught on in the West. something is changing

by

Superapps are mobile applications that offer many unified services, from messaging to mobile payments and much more. In Asia, especially China, They are the default formula that has been successful for years with apps like WeChat, Meituan or AliPay. In the West we are more into specialized apps, but the market is beginning to show clear signs of approaching the Chinese model. The Uber case. Uber just announced the integration of hotel reservations in your app through its alliance with Expedia. In this way, in the same app we have car reservations, food delivery and hotel reservations, a solution that is quite similar to the model of a Chinese super app like WeChat, which integrates all types of services under one umbrella. Uber’s goal is that, by offering more services, the Uber One subscription will be more attractive to consumers and thus increase its income. An important detail: Uber CEO Dara Khosrowshahi was previously CEO of Expedia, so this alliance does not seem coincidental. TikTok Shop. Uber is not the only one that is following this strategy, there are other proposals that also point in the direction of consolidation. We have the clearest example with TikTok and the integration of the marketplace. ByteDance has managed to export a very Asian model: see a product in a video and buy it without leaving the app. TikTok Shop has been in Spain since the end of 2024 and, at the end of 2025, there is already a TikTok account more than 12,000 stores operating on its platform. The adoption data is positive, but the model is still very far from the penetration it has in China. There have been attempts. The creation of a super app that succeeds in the West was Elon Musk’s obsession when he bought Twitter. The bet did not work out and today X continues to be what Twitter was: a microblogging social network. PayPal also tried its superapp version integrating hotel reservations with little travel. Years ago there was talk that WhatsApp could be the WeChat of the West, but despite having been adding functions, it is still a messaging app. Looking to the future, we have the case of ChatGPT and its path to a super app that integrates the chatbot with the Atlas and Codex browser. Why in China yes and here no. It is not a question of simple preferences, but has a structural explanation: Internet penetration in China was much slower and, in some ways, skipped the era of the personal computer. While Western consumers came to the smartphone with already formed habits (a browser to search, an email program, an online store), the Chinese did so directly from the mobile phone. By not having already created habits, this made the creation of these “everything apps” much easier. Likewise, the penetration of credit and debit cards was also slow and many consumers switched from cash to mobile payments, hence apps like WeChat or AliPay have become the default standard for paying everywhere. Another factor that plays in favor of the adoption of these apps is that they had no competitors. With the entire Google and Facebook suite blocked by the Chinese government, these apps did not have to compete, but rather filled a void. And of course there is the regulatory issue and institutional support. in China you can pay taxes from WeChatapply for a business license or pay a traffic fine without leaving the app, because the Chinese government actively integrated its public services into these platforms. In the West, the merger between a private company and the State would generate immediate political and regulatory scrutiny. something is changing. On the one hand, the perception we have of China from the rest of the world has been changing in recent years. The success of TikTok, the Labubu, the popularity of electric cars… are symptoms that China has become a cultural reference and technological. This opens a new opportunity for success. On the other hand, there is a new variable: AI. The arrival of AI tools is already changing our information-seeking habits and has the potential to function as a layer on top of everything we already use, connecting services that previously lived separately.

Unamuno and Borges in all homes in Spain for 25 pesetas

by

If you have lived in Spain (or someone in your family has done so) at the end of the sixties of the last century, there is a very high chance that copies (perhaps all of them) of the Salvat RTV Library that were sold in newsstands from 1969 passed through your house. Aesthetically unmistakable (paperback covers in light tones without photos or illustrations, low quality paper, very rough binding), this collection did a lot to introduce a series vast amount of essays and fictions, many unpublished, in Spanish homes. It is probably the most shared cultural object in the country’s recent history. Government origins. At the end of the sixties, the Ministry of Information and Tourism, then directed by Manuel Fraga, called a competition among private publishers to finance and distribute a literary collection of mass reach. The project had the explicit support of Radio Televisión Española, whose initials would appear on the cover of each issue. What emerged from there was a collection of one hundred books that would end up selling more than thirty million copies. The contest. The Ministry ended up choosing the joint proposal of two companies with very different profiles: Salvat Editores, founded in Barcelona in 1869, with decades of experience as a publisher of enclopedias; and Alianza Editorial, newly born in 1966 at the initiative of José Ortega Spottorno (son of the philosopher José Ortega y Gasset, future founder of ‘El País’) and with the no less legendary collection ‘The Pocket Book’ already underway. The importance of television. The ‘RTV’ label was of great importance in promoting the dissemination of the collection. National Radio of Spain and Spanish Television authorized the use of their initials as official support, which gave the collection visibility and institutional legitimacy that was very important at that time. Furthermore, the books were advertised on television just when the progressive penetration of the appliance in Spanish homes was making it one of the main leisure options for Spaniards. Photo by Alberto Haj-Saleh Spain reads. The Spain that saw the birth of books was still suffering the echo of the decades of post-war cultural isolation, and many foreign authors were still circulating in imported or clandestine editions. The Press Law of 1966promoted by Fraga himself, had partially lifted the weight of censorship, but it still continued to exist. The researcher Francisco Rojas Claros states in ‘Cultural management and editorial dissidence in Spain (1962-1973)’ that the Salvat Basic Library was for many families the first real opportunity to access notable works from different periods, with correct translations and at a price that did not leave out the working classes. What was in the collection. The committee that selected the books (here the complete list) was made up of Dámaso Alonso, the Guatemalan Nobel Prize winner Miguel Ángel Asturias and the French writer Maurice Genevoix. Each volume included a prologue signed by a figure linked in one way or another to the work, and the selection combined universal classics (Shakespeare, Dostoevsky, Molière, Swift, Tolstoy, Dickens, Stevenson) with Spanish literature from the Golden Age (Quevedo, Calderón, Lope), Spanish authors of the 20th century (Unamuno, Baroja, Machado, Delibes, Cela) and a Latin American selection (Borges, Cortázar, Vargas Llosa, Onetti, Asturias himself). And yes, somehow Orwell’s ‘1984’ passed the censorship filter. The magic of 25 pesetas. The RTV seal was important for the popularization and dissemination of the collection, yes, but nothing was more important than the price of 25 pesetas (with adjusted inflation, we would be talking about a little less than five euros today). At that price, books were within the reach of an expanding middle class and working-class families with a stabilized salary after the years of developmentalism. They were not as cheap as newsstand novels were, but they were affordable if bought week by week. Mine. Let’s finish with a personal note: I only have one book from that collection where I first tasted Poe, Wilde, Hammett and Clarke. As everyone who has come to touch it knows, over time the glue of the binding became worn and the pages began to come off (note in the header image how the owner has had to re-stitch the spines of some copies). The book that I read and reread dozens of times was ‘Spanish graphic humor of the 20th century’, number 46 in the collection, an absolutely monumental anthology of cartoons, satirists and graphic humorists, to the point that I would say that it has not been surpassed. Many of those books (those mentioned in the previous paragraph, without going any further) I have subsequently read in better and more convenient editions, but this volume remains unique, has not been reissued and is among my favorite volumes in my library. Furthermore, since so many copies were distributed, it is relatively easy to buy it second-hand at a ridiculous price, so you know: let it not be said that we only recommend things with a built-in microchip here.

The animal testing of the elixir for future warfare has been a success. Now the most difficult thing remains: making it work in humans

by

In 1667, the French doctor Jean-Baptiste Denis performed one of the first transfusions of history using lamb’s blood on a human patient, convinced that it could calm his behavior and save his life. The experiment generated such controversy that ended up being banned in several countries for decades, leaving a lesson that has accompanied medicine since then: when it comes to replacing blood, each advance opens a door… and also a risk that is difficult to foresee. An experiment that redefines war medicine. A lot has happened since that test by Denis, but now it is making strong noises again with the development of a powdered blood substituteone that marks one of the most ambitious advances in military preparation for future conflicts, where conditions no longer guarantee rapid evacuations or immediate access to hospitals. In this context, the idea of ​​transforming blood into a portable and stable resource ceases to be science fiction and becomes a solution, or perhaps an operational necessity. They counted on Insider that, for the Pentagon, what is at stake is not only improving logistics, but changing the way soldiers’ lives are saved in environments where every minute counts and medical infrastructure may not exist. The “elixir” that seeks to change war. The program powered by DARPA has managed to turn a complex concept into a potentially revolutionary solution: a powdered blood substitute that can be stored, transported and activated in a matter of seconds. This system is presented as an alternative to the current model, where fresh blood is limited, perishable and difficult to move in combat zones. The key, they say, is in its operational simplicity: mix the contents with sterile water and have a vital resource at the exact moment it is needed. Success in the laboratory. The initial results have been promising enough to generate expectations within the military and scientific field. After demonstrating its viability in controlled environments and later in animal models, the project has overcome one of the most complex phases of biomedical development. In other words, the advance suggests that the concept works in biological termsopening the door to real applications in scenarios where conventional transfusions are not possible. The great challenge. There is no doubt, despite of the advancesthe final jump remains the most difficult of all. The next step is to overcome the regulatory processes and demonstrate that the system is safe and effective in humansa long path that involves clinical trials, medical validation and approval from regulatory bodies. In fact, this is where many promising developments stall, not because of a lack of technology, but because of the complexity of ensuring that they work in real conditions without unexpected risks. A necessity. They counted in their report in Insider that interest in this type of solutions does not arise in a vacuum, but as a response to a profound change in the nature of conflicts. Conflicts have shown that air superiority no longer guarantees rapid evacuations, and the wounded can be trapped for hours without access to advanced medical care. In these contexts, the immediate availability of blood becomes a critical factor that can make the difference between life and death. Limitations of the current system. In the absence of alternatives, the armed forces have resorted to methods such as emergency transfusions among soldiers, known as “living blood banks.” Although effective in specific situations, these solutions depend on the availability of donors and cannot scale in scenarios with multiple casualties. Again, this highlights the need for a more robust solution, capable of responding to high-intensity situations without relying on improvised resources. Beyond science. The future of this technology announced by DARPA depends not only on its medical effectiveness, but also on its economic viability. The production, distribution and adoption of synthetic blood require significant investments in a sector where margins are traditionally low. Without a sustainable model that incentivizes companies and hospitals, even the most promising advances can remain in the experimental phase, never reaching the battlefield. Be that as it may, the objective set is more than ambitious: to turn development into an operational tool before end of the decade. To achieve this, almost nothing: coordinate science, regulation and industry in an accelerated process that avoids the usual blockages in such complex projects. But if successful, this sort of modern “elixir” could redefine war medicine, bringing the ability to save lives directly to where it is needed most.

that the birds recover their original song

by

Noise is an invisible pollutant, but its effects can be seen. To begin with, the natural soundstage changes, altering the behavior of animals and affects health of humans and other species. It is true that in cities noise pollution is usually overshadowed by other pollution such as air or water quality, but its consequences are equally tangible. At the beginning of this century, studies on urban birds They found that noise caused by human activity causes birds to sing at higher frequencies to avoid masking traffic, a source of low-frequency noise. What Paris has achieved. As collects the paper published in Oxford Academicthe French capital has been fighting noise for decades directly and indirectly, especially focused on traffic, which shows a transformation in its urban mobility: it has gone from having 250 kilometers of bicycle lanes in 2003 to 800 kilometers in 2023, recycling traditional traffic lanes, with sound-absorbing asphalt, lowering speed limits, the expansion of electric vehicles and the installation of acoustic chambers capable of detecting and fining the noisiest vehicles (the famous “Medusa radars“). The result is obvious: the government agency Bruitparif demonstrates that Paris is today approximately three decibels quieter than it was almost 20 years ago (since 2008). It may not seem like much, but it is worth remembering that the decibel scale is logarithmic and that in practice this reduction represents approximately half of the previous sound intensity. Why is it important. The WHO is clear: Noise is the second most harmful environmental stressor for health in Europe (behind air pollution) and prolonged exposure to it increases the risk of cardiac ischemia, hypertension and sleep disorders in humans. The European Environment Agency details in its 2025 report that noise contributes to 49,000 new cases of ischemic heart disease annually on the continent. The prestigious The Lancet states in this paper that nocturnal noise causes sleep fragmentation, which raises blood pressure and, in the long term, damages the endothelium. If we stick to birds and their song, it is something like human language: they are culturally transmitted from generation to generation and changes in song are also learned by individuals of the same species in the environment. But it goes beyond changing a sound: it affects your ability to attract a mate, warn of danger, defend your territory or simply communicate. And be careful because this also affects other species such as whales because of the noise of the boats either the bats. This other one study published in Proceedings of the Royal Society B which analyzes 160 species of birds since 1990 found that noise significantly impacts communication, risk behaviors, feeding, aggression and physiology, with a clear negative effect on reproduction. Context. He Noise Prevention Plan in the Environment of Paris seeks to transform the French capital into a more livable city, becoming a living laboratory where urban planning and sensory planning combine to try to curb the impact of decades of acoustic degradation due to automobile dependency. For the study of Parisian birds, the great tit is the sentinel, using recordings of its songs both in the center of Paris and in the Fontainebleau forest as a wild reference. This observation is not new: already in 2006 a study showed that the chickadees that sing under the Eiffel Tower did so with a minimum frequency 400 Hz higher than those that sang in the Fontainebleau forest. This pattern has been replicated in other cities and species and the result is the same: it is common for birds to increase the minimum frequency of song in response to urban noise. The pending subject. Even though noise has decreased, Parisian tits continue to sing with significantly higher minimum frequencies than non-urban birds, and these frequencies have not decreased along with noise reduction. The explanation, according to the research teamis the cultural mechanism: young birds learn to sing by imitating the adults in their environment and for decades the only adults available to teach them sang high because it was the only way to make themselves heard. Now the city is quieter, but there are no teachers who sing gravely to learn. The habit persists even if the original cause has diminished. San Francisco in COVID-19 leads the way: during the pandemic background noise was reduced by about seven decibels and the white-crowned sparrow responded by singing at lower frequencies. Nature is speaking loud and clear: the reduction achieved by Paris is real but insufficient.

more than 2,000 years without hair and a sacred mission in the underworld

by

When I did the 1930s Mexican nationalism began to reclaim its pre-Hispanic past and rescue icons of the country. one in particular which stood out for its symbolism: the xoloitzcuintle. His name may not mean much to you, but you’ve probably seen him in photos or movies like ‘Coconut’by Pixar. He xoloas it is commonly known, is a dog breed originally from Mexico that stands out for two great reasons. First, because of his appearance, bald and athletic. Second, because of its history, which dates back to several millennia ago and connects with the Aztecs. For them the xoloitzcuintle was not just a pet, but a symbol associated with death and the last companion of the deceased on their journey to Mictlanthe Mexican underworld. A name that says it all. It seems like a tongue twister, but “xoloitzcuintle” is not only the name of a breed of dog native to Mexico. The word, from nahuatlthe language of the ancient Mexica, is in a way a description. There is who believes which is the combination of ‘Xolotl’the god of fire and death, and ‘itzcuintli’, which means dog. Others consider that the first part of the word is more of a nod to the hairless appearance of the animal, so it would be translated as “strange or wrinkled dog”. In either case, it is a fantastic business card for the ‘xolo’, a breed that has been linked to Mexico for millennia and stands out both for its exterior appearance and for its history and symbolic value. Hence, in the 1930s, the country’s nationalist movement “exalted her as a national symbol,” comment Raúl Valadez Azúa, from the Anthropological Research Institute (IIA) of the National Autonomous University of Mexico, UNAM. No hair or premolars. Its symbolic value may not be obvious, but as a breed the Xoloitzcuintle is unmistakable. Although there are examples of different sizes and varieties with and without hair, usually their specimens are distinguished by two characteristics: They are hairless and lack premolars. The reason must be sought in their genetic pool. During their first embryonic phase, three layers are formed in the xoloitzcuintle, like remember from the UMAN: the endoderm, mesoderm and ectoderm. The latter, however, is affected by a mutation that affects the teeth and fur. “It cannot be denied that a hairless dog is at a disadvantage. For example, when fighting with other dogs or in the face of climate changes. Despite this, after 2,000 years, it is still here,” reflect Valadez. Its peculiar condition also presents some advantages that have favored its bond with humans. Since it lacks hair, it is easy for us to feel its heat, which in the past caused xolos to be used with therapeutic purposes to relieve rheumatism or muscle pain. Just like huge hot water bottles. “A decision of the gods”. “The people of the region considered that, although the bald dog was a strange animal, its appearance responded to a decision of the gods and that therefore it was not up to them to kill it or decide its fate. Thus, they accepted it like the other dogs and called it xoloitzcuintle,” duck the UNAM expert. The result is fascinating: a characteristic that a priori could have represented a disadvantage compared to other races, ended up becoming a sign of identity that strengthened its symbolic value and the bond with men. An ancient race. If the appearance of the xolo is peculiar, its history is no less so. Experts believe the breed can date back to at least 2,000 years ago (there are those who place it even further back, to 3,500 years ago), emerged in western Mexico and after 500 years it began to disperse following two routes: one took it to South America, the other to Tula, Teotihuacán and Mayan territories. Its link with humans is also very old. Researchers have found remains dating back to 7th century and they seem to associate it, already at that time, with funerary contexts. They even suggest that he was attributed a role as guardian of sacred spaces. The Aztec dog. The remains of bones and ceramic fragments have allowed experts to better understand the role that dogs had in pre-Hispanic Mexico, where they were used for both eminently practical and symbolic purposes. Valadez remember For example, there are testimonies that speak of ritual sacrifices of hairless dogs in times of drought or during mass ceremonies, as well as others that reveal how their scavenging habits ended up associating them with death. “These animals were linked to the underworld because somehow what they ate in the underworld was converted into fecal matter, organic waste that was incorporated into the earth to pass to the underworld and, subsequently, returned to the earth as fertilizer that nourished the plants and, therefore, life,” reflect the expert However, if the xolo stands out for something, if something has earned it the nickname ‘Aztec dog’is the spiritual role that was attributed to it. The last companion. Its role in pre-Hispanic religiosity was so relevant that even today they highlight it the Mexican authorities, who have even designated the October 27 as ‘National Xoloitzcuintle Day’. Mythology claimed that when a person died, their essence undertook a journey to the underworld (Mictlán) that forced them, among other things, to cross the river Chiconahuapan. For that journey, however, he needed the help of the xolo, who would lend him a hand (or not) depending on how he would have behaved in life. Over the last few decades, researchers have found remains of dogs in graves, which has allowed them to confirm the belief that the deceased should be buried accompanied by a dog. Of course, with an important nuance: although at first it was believed that xolos were the favorite breed for that rite, the really relevant factor was the color of the coat. It had to be toasted. Other meanings were attributed to white or black hair that made them invalid for the journey to the afterlife. … Read more

The CEO of Nvidia believes that we are in a new industrial revolution where AI will not replace us: it will micromanage us

by

Artificial intelligence has been available to users and companies for a few years now and we are at a point where they converge several ideas about AI and the future of work. There are several open fronts such as if AI will replace usif it will only be a tool or if, instead of freeing ourselves from the workload we carry, will add more to us. But the CEO of Nvidia, a Jensen Huang who has no trouble spilling his tongue, has another opinion. AI is going to micromanage us. Micromanager. A few days ago, Huang attended a talk at Stanford Business School. At these events, company CEOs usually leave motivational messages and talksbut I don’t know if in this case it would motivate someone who is looking for a job. During his panel, the Nvidia boss commented that, right now, “we are doing things faster, on a larger scale and we can think to do things we never imagined.” That part of the speech is fine, but he went on to note that “AI agents will harass you, micromanage you, and you will be busier than ever.” Like a good 1st century Roman baptisterywho wouldn’t like having an AI agent egging you on? Will create more jobs. Lately, Huang has chosen to blurt out headlines and vaguely elaborate. At the event, he also commented that these agents we have help us explore new avenues of work, do that work better and make it more profitable. He also addressed the great controversy, that of the supposed great replacement. On this, his opinion is that there will be some jobs that will be redundant because AI will be able to do the same as a human, but he considers that, in general, there will be humans with new jobs to adapt to. “I think we are going to create more jobs. There will be more people working at the end of this industrial revolution than at the beginning of it,” he says. Insecurity. It is curious that you compare it with the industrial revolution at a time when there is concern, above all, about the instability of the labor market. Huang ha commented that computer engineers are busier than ever and it makes sense, the problem is what happens next and what is happening with all those who are not dedicated to tasks strictly related to AI. In an article by Fortune published a few weeks ago, the issue of layoffs directly related to artificial intelligence was addressed. An example is Jerome Powell, president of the United States Federal Reserve, who warned that AI is quietly impacting the labor market as job creation is practically at zero. Another is that of Dario Amodei, CEO of Anthropic, who believes that “entry-level” jobs will be reduced by half in the next 18 months. And then Microsoft’s AI chief, Mustafa Suleyman, predicting that AI will cause many white-collar jobs to collapse in that same time frame. AND Meta is going to do without 8,000 employees as it transforms into an AI company. All this while, on short video networks there is a lot of content of young people saying that they have a university degree and are rejected at Target or McDonalds. The AGI has already arrived. Well no. HE esteem that, during 2025, some 55,000 people in the US will lose their jobs directly due to AI. It is only 4.5% of all layoffs, but a significant number that, if forecasts are met, will multiply by several figures over the coming months. For now, so far in 2026, esteem that technology companies have laid off 92,000 people, not all of them must be related to AI, but a scary number if we take into account that, during 2025, the total was 120,000 people. Just 28,000 less in just four months. But, beyond that, the prediction that an AI agent will not take our jobs, but rather will be a tiresome second boss, is not the only thing that Huang has commented recently without going much further. A few weeks ago, on Lex Fridman’s podcast, he already commented on things like that workers must be clear about the purpose of their work and that the tasks and tools they use to do it are related, but they are not the same. Also He commented that we had already arrived at the AGI (artificial general intelligence) giving an example that it has nothing to do with an AGI that, for now, remains theory. A black hole of money. Byan Catanzaro is the vice president of deep learning at Nvidia and has commented that AI currently costs more than human employees. “For my team, the cost of computing far exceeds that of employees.” It must be taken into account in this that AI is not an abstract entity: it is a huge investment in hardware, data centers and energy. According to the calculations According to Keith Lee, professor of AI and finance at the Swiss Institute of Artificial Intelligence, AI expenditures will be $5.2 trillion by 2030 in a conservative estimate and $7.9 trillion in a more aggressive one. But more interesting is what he comments about the fact that fixed subscriptions are not making money for companies because they do not cover operating costs. And that, at a time when companies like OpenAI and Anthropic should not take long to go public, is something to take into account because they will stop receiving millions from other private companies to have to respond to investors with their product and benefits.

The race to develop models of artificial intelligence (AI) that the US and China maintain in their struggle for world supremacy is entering a new phase. And the physical applications of AI are gradually gaining prominence. By “physical applications” we mean the integration of one or more AI models into a mechanical device, such as a humanoid robot or a machine for industrial automation applications. The interesting thing is that the rules that will determine which countries will lead this emerging industry are different from those that currently govern competition in the field of AI models and software applications. And they are so for a reason: the robustness of the supply chain plays a fundamental role when the product stops being immaterial and takes the form of a cutting-edge hardware solution. In this scenario, Taiwan, Japan, South Korea, and, above all, China, have a great advantage over the US and Europe. China is committed to the strategy with which it has managed to dominate the electric car Before continuing to investigate the industry specialized in the development of physical applications of AI, we are interested in diverting our gaze for a moment to the semiconductor market. At the moment in Asia they are manufactured 90% of memory chips, 75% of microprocessors and 80% of silicon wafers. These figures are overwhelming. So much so, in fact, that in the medium term they remain absolutely out of reach of the West. It will be very difficult for the US and Europe to compete with the Chinese companies UBTech Robotics, Agibot or Unitree Robotics The electric car market also clearly illustrates the strength of Asia in general and China in particular. The country led by Xi Jinping leads it with a global market share of 62%. On the other hand, the South Korean companies LG Energy Solution, SK On and Samsung SDI accumulate a joint global quota in the market for batteries for electric cars of 16%. And the Japanese Toyota produces more than one million hybrid vehicles per year. Japan’s position is peculiar because leads the production of hybrid carsbut it is lagging behind in the pure electric car market. Whatever China’s strength in the electric car market and Asia’s leadership in the integrated circuit manufacturing industry have been built on a very robust supply chain and overwhelming production capacity. Jixun Foo, the senior director at venture capital firm Granite Asia, which specializes in technology investments in Asia, ensures that “AI is not just about models or software applications (…) If we look towards Asia our advantage is in the supply chain, hardware and engineering capabilities.” That’s the key. China has opted for the same strategy in the physical applications of AI industry that has led it to lead the electric car market. Its meticulous control of the entire supply chain, its high manufacturing capacity and its cost optimization in all probability They are giving you a very important advantage in the industry of humanoid robots and machines for industrial automation applications. And not only in its struggle with the United States; It will be very difficult for Europe to compete in a market in which Chinese companies such as UBTech Robotics, Agibot or Unitree Robotics are already fully established.

The megacity you haven’t heard of is in China and aspires to be the largest in the world

In the world there are big, huge, huge cities and then others that are almost a country in themselves, like Jing-Jin-Jithe huge conurbation that has been taking shape in northern China for years. And “country” can be taken in its most expansive sense. If they are fulfilled the forecasts launched by its promoters more than a decade ago, the megalopolis will host between 110 and 130 million of inhabitants, in addition to a robust business muscle. Its size will also take away the hiccups: is spoken of more than 200,000 km2double that of all of Portugal. It may sound like science fiction, but there is a very simple explanation: Jing-Jin-Ji is not a city founded from scratch, but a new way of understanding and organizing Beijing, Tianjin and the province of Hebei to shape an urban titan. Rethinking Beijing. Although it does not reach the levels From Tokyo, Delhi or even Shanghai, Beijing is one of the most populous cities on the planet. Its stable population easily exceeds 20 million of people, more than all Romania or Netherlands. That huge number of people move every day to go to school, the doctor and of course to companies that may be close by. several hours of their houses. If we add to that the role of Beijing as the capital of one of the greatest potentials in the world, the result is an (almost) impractical megalopolis, polluted and in which complications the services. To face such a challenge and prevent the exodus from the countryside from ending up collapsing the city, in recent years the Government has resorted to several solutions. One has been limit the population. Another is to rethink Beijing itself so that it is no longer just the capital of China or a mere metropolis, but part of a much larger conurbation. The objective is twofold: to relieve pressure on the capital and to promote a new industrial hub, one capable of replicating the success achieved in the Yangtze River Delta or Guangzhou and Shenzhen area. A new giant: “Jing-Jin-Ji”. With this premise, a decade ago the Chinese authorities decided to go for what is probably one of their most ambitious projects: Jing-Jin-jia word that hides a nod to the cities of Beijing, Tianjin and Ji, which is how the province of Hebei is traditionally known. That business card speaks for itself idea. The idea is strengthen the bond between those three territories in northern China, distributing part of the crushing burden that now falls on the capital, improving communications and betting on a distribution of specialized roles. The story of Jing-Jin-Ji can soar at least to the National New Urbanization Plan presented by the Government for the period 2014-2020. In it, China, a nation already accustomed to megacities, advocated the promotion of a dozen “urban clusters.” The greatest of all would be Jing-Jin-Ji, in which Beijing would embrace (in an almost literal sense) with Tianjin, which is another of the biggest cities of the country and nearby cities in Hebei province. More than theory (and politics). The project received Xi JinPing’s blessing just 12 years ago, in April 2014and was sold with a display of astonishing data. Its objective was neither more nor less than to bring together a region of more than 215,000 km2 in which some 130 million people would live in 2050, generating a powerful industrial and commercial hub. It could have remained just that, an ambitious idea, but a quick review of the newspaper library confirms the extent to which China was determined to push it forward. The following year, in 2015, The New York Times confirmed that Jing-Jin-Ji was beginning to become a reality. Shortly after Guardian informed of the plans to create Xiongan, a large city located just under 100 km from Beijing that would allow the urban framework of Jing-Jin-Ji to be articulated. It was just one of the measures to consolidate the new megalopolis. The most effective of all was the reinforcement of rail and road communications. In 2016, China actually approved an ambitious investment plan to build kilometers and kilometers of roads and reach the middle of the century with about twenty of railway lines. Is it just infrastructure? No. Improving communications is a fundamental part of Jing-Jin-Ji, but not the only one. Another, equally important, is the distribution of roles between the regions. He starting point It was simple: Beijing would consolidate itself as a political, cultural and technological center while Tianjin would establish itself as an export port and manufacturing hub. As for Hebei, there was a commitment to also orient it towards industry and wholesale trade. In the background, slide China Briefingthere was the desire to bet on industrial clusters focused on emerging sectors, such as electric vehicles, the biopharmaceutical industry or robotics. To achieve this distribution, of course, it was not enough to set guidelines on paper. In 2015, the Beijing authorities announced his plans to refocus the capital, moving certain services, such as wholesale markets and administrative offices, out of the urban center and moving some services to suburban areas or even to Hebei province. The importance of gestures. Perhaps the best proof of the extent to which the Government wants to keep the project alive is that, from time to time, the Chinese press publishes articles reviewing the progress in the creation of Jing-Jin-Ji. It happened in April 2024coinciding with the tenth anniversary of the presentation of the plan, and it happened again in 2025, when CGTN He published an article to make it clear that Beijing’s suburban dream is advancing little by little. His chronicle highlights the increase in economic production in the region, the opening of new stretches of road that allow travel times to be cut, the reinforcement of public transport or collaboration at an economic level and when providing services. The local press also highlights that the region “has become an innovation center” capable of attracting companies. Of course, there are also important challengeshow to achieve greater … Read more
