The United States promised to be very happy manufacturing its own chips. Nvidia just spent 150 billion in Taiwan

by

Houston, we have a problem. A couple of days ago the CEO of Nvidia stood on the stage at Computex in Taipei and said an inconvenient truth for the United States: “Taiwan is the epicenter of the AI ​​revolution. This is where chips and packaging are made. This is where systems are created. This is where AI supercomputers were created.” The setting was Computex 2026, Asia’s biggest tech event, and it wasn’t a compliment to the host, it’s a real depiction of how the industry works. It may sound paradoxical for an American company and at a time when The United States wants to reindustrialize with chipsbut he needs it. It is a structural issue. The harsh reality of profitability. Nvidia plans spend 150,000 million dollars a year in Taiwan, much more than the 100,000 million they spend now and with an abysmal difference compared to the 10,000 and 15,000 million five years ago. If it sounds silly, it’s because it is, but so is its billing: in the first fiscal quarter of 2026 billed 81.6 billion dollars, 85% more than the previous year in that same period. Also its benefit it’s already going off the charts: 58.3 billion, more than triple compared to the same period last year. That this money goes to Taiwan and not to the United States is due to technical and objective issues: Taiwan produces 90% of the most advanced chips in the world, according to a study by the Stimson Center. Of that Taiwanese production, TSMC controls 70% and is going to invest between 52,000 and 56,000 million this year. Bottom line: If Nvidia wants cutting-edge manufacturing capability, it has to be there. Why is it important. The best way to see it is to put Vera Rubin on the table, who In Huang’s words it is “probably the biggest product launch in Taiwan’s history.” Each system contains about two million parts and is assembled with 150 suppliers, almost all Taiwanese. This mechanism is not assembled by decree or in a legislature: it requires years and putting billions of dollars on the table. There is no factory in Arizona that can do something like this at least until 2030. Constellation will be Nvidia’s new headquarters in Taipei and will come to stay permanently: 4,000 engineering professionals will work in that center that according to Huang It will be operational by 2030. It is no longer that it buys in Taiwan, it is that the most valuable semiconductor company in the world is building the heart of its R&D in that core, an island 10,000 kilometers from the United States. A splash of cold water on Trump’s aspirations. Context. In January 2026, Taiwanese companies they committed to invest $250 billion in semiconductors and AI in the United States, as part of a trade agreement with Washington. Because Taiwan and the US are a symbiosis: each needs the other to maintain its position in the race for AI. The investment of a private company like Nvidia is another expression of this pact. In fact, Nvidia is not the only one: AMD is doing exactly the same: associate with Taiwanese manufacturers such as ASE, SPIL and Wiwynn with their Helios AI platform on the horizon (expected for the second half of 2026). That the two largest AI chip designers in the world strengthen ties with Taiwan is confirmation that the island’s industry is strategically necessary for the entire industry, not a particular bet by one firm. The elephant in the room: China. China’s role in this story is twofold: it is a threat and also a client. According to Reutersin 2026 Chinese companies have placed orders for more than two million units of the H200. Trade restrictions have made the operation difficult, but they have not been able to prevent it. One of the last cases point upon the arrival of a shipment of Nvidia AI chips to China via Japan. Nvidia lives in a contradiction from which it cannot escape: Its supply chain is on an island that China considers its own. China, which is its largest potential market, is blocked. Washington prohibits him from selling to Beijing while asking for independence from Taipei. And judging by his statements, Jensen Huang has bet everything on continuing to walk that wire. Yes, but. The Nvidia CEO forgot one problem in his speech: Taiwan makes the overwhelming majority of the world’s most advanced chips, but TSMC’s diversification into Arizona, Japan and Germany will not be ready before 2028 at best. That is to say, there are almost four years ahead in which Nvidia depends totally on Taiwan, a country that matters 97% of your energy. Furthermore, the atmosphere in the Strait of the same name is increasingly heated. Concentrating the production of its most critical component in a geographically hot spot is dangerous to say the least: if something explodes, there is no plan B. The closure of the Strait of Hormuz has reminded us of this the hard way.

why understanding these acronyms is the difference between buying an air purifier or an expensive fan

by

At first glance buy a purifier air can be a simple task, but as soon as we start reading the specifications… we can easily get involved, especially with some of them such as the type of filter. Here we must be especially careful because it is possible that we find HEPA filters or HEPA type filters, and they are not the same. In fact, with each of them we will have a totally different experience. How a HEPA filter works HEPA (High Efficiency Particulate Airor air with high efficiency particles) is a quality standard for filters, so if we see it in a purifier we can know that it meets rigorous tests to guarantee efficiency in retaining particles such as dust, pollen, mold and even bacteria or viruses. If we get a little more technical, bacteria measure between 0.5 and 5 microns while viruses measure between 0.02 and 0.3 microns. HEPA filters must be capable of retain at least 99.97% of particles having a size of 0.3 microns (particle size most difficult to physically filter). If it is not capable of this, it is not a HEPA filter. However, you have to be careful because this is where HEPA type filters come into play. What is a HEPA type filter If we see that a purifier has a HEPA type filter, we may think that it meets the standard we have discussed. But this is not the case, and they can be much less efficient. The expression “HEPA type filter” is usually used as a claim for some purifiers, generally inexpensive, although it is more normal to see them in other devices such as robot vacuum cleaner. These filters They are not as effective because they have not been tested with the tests that HEPA filters are subjected to, and it is possible that they do not even comply with the European standard that defines the different kinds of HEPA filters that we can find. Can they retain bacteria? Yes, but they do not have certified efficiency. How purifiers work The purifiers have a fairly simple structure: Inside there is a motor, a fan and a box where the filter is located.. Its operation is summarized in that the motor makes the fan move to attract particles and deposit them in the filter. However, it is worth mentioning that the filtering process is more complex. Inertial impact: affects large, heavy particles that travel at high speed. The particles cannot change direction quickly, so they continue straight until they collide with the fibers until they become stuck. Direct interception: some medium particles that follow the air flow pass very close to the fibers until they come into contact with them and remain adhered, which is known as direct interception. Brownian diffusion: on the contrary, small particles do not follow the air current in a straight line, so they continually collide with the gas molecules in the air. This movement increases the probability that the particle ends up hitting a fiber and becoming stuck. HEPA-type filters can retain certain particles, but they do not have certified efficiency. It’s not that they are useless, but they simply may not be as effective as HEPA filters. The good and the bad of both options, face to face hepa filters hepa type filters THE GOOD 🟢 They are capable of better filtering dust particles, bacteria or viruses. They are usually found in cheap purifiers, being interesting for devices whose purification function is secondary. THE BAD 🔴 They are found in more expensive purifiers, so they are aimed at devices whose purification function is the main one. They are less efficient than HEPA filters. Ideal for: People looking to improve the air quality in their home. Economical devices whose purification function is secondary. What purifier should I buy then? At this point you may have wondered whether or not it is worth buying a purifier with a HEPA type filter, and the truth is that it is, although it depends on what we are looking for. 👉 Choose a purifier with a HEPA filter if: You want to retain large and small particles for a cleaner home, from dust to viruses and bacteria. 👉 Choose a purifier with a HEPA type filter if: You only want to retain large particles such as pet hair, dust or lint. Recommended models Philips 2200 Series He Philips 2200 Series It is an air purifier with a HEPA filter that has a fairly small format. It incorporates a three-layer system composed of a prefilter, a HEPA NanoProtect and active carbon to capture 99.97% of particles up to 0.003 microns (3 nanometers) through NanoProtect technology, a technology that allows even smaller particles to be captured thanks to electrocharging. It can be controlled from your mobile phone to program routines and is capable of capturing odors, bacteria, viruses and larger particles. Philips 2200 Series Air Purifier The price could vary.

Festivals turned food trucks into a money-printing machine. Now they have a problem: Ozempic

by

During the marathon days of the past Coachellaone of the most important music festivals in the world where, paradoxically, music is the least important thing, an image caused a certain sensation on social networks: the total absence of lines at the food stalls. To the plethora of content generated by the festival, a showcase for social networks where only the show by Niece Carpenter and the revival by Justin Bieber caught some attention strictly musically, we had to add the “get ready with me” on Instagram and the usual parade of looks themed, generally quite unsuitable for the Californian desert. In the background a silent revolution was brewing. Because within this hyperaesthetic ecosystem there was a shadow. In the videos of many influencers and tiktokers We were able to observe a scene repeated day after day: non-existent queues to get food (even when it’s free), facing crowded lines to buy sunglasses or other accessories. For many, the reason was obvious: Ozempic. We can interpret it from irony or, on the contrary, as a clear cultural symptom that is deeper and difficult to ignore. Because, if something seems evident, it is that, in a festival where consuming aesthetics is much more important than consuming food, the Ozempic era has found its best showcase. Less hunger = less business Anyone who’s been to a festival, especially in recent times, knows what it’s like. Until recently we went with our eyes closed and our wallets open, assuming that, in addition to the increasing price of admission, we had to pay absurd amounts for a cold burger or a pad thai stale at Michelin star price. We got into the game and no one was surprised by the exorbitant prices, those 20 euros on average per plate were part of the ritual of the festival experience; but something has started to change at Coachella. To get an idea of ​​the importance of this change: the economic volume of its gastronomic industry covers more than 100 positions. Ozempic and derivatives are completely redefining the cultural codes of the last decade. Starting from the basis that each person does with their body what they consider, it is true that we were already noticing in red carpets and derivatives that curves are beginning to go out of fashion; with bloody examples because they are carried out by former standard-bearers of the movement curvy. Actresses and artists like Rebel Wilson, Barbie Ferreira either Meghan Trainor show a change in their figure that advances from photocall in photocall. Little by little this permeates society; and also leaves a side effect that someone may consider unexpected. It is not only transforming bodies but also habits and, among them, our relationship with food in spaces of mass leisure. This change in the psychological relationship that we establish with food and the hunger-suppressing effect means that this character is eliminated from the equation. hedonist and impulsive. If the desire for food ceases to exist, the key turn occurs. For years festivals were governed by a simple rule: the economic margin is not so much in the entrance, but rather in everything that happens inside. In this mechanism, food is a key element with these inflated prices, encouraging impulsive decisions in marathon days that invite consumption. This is where Ozempic has broken the model at Coachella, fully attacking that impulse. In this showcase where it seems that eating is “annoying,” a drug that controls hunger is not useful, but rather more than consistent with the environment. And yes, Coachella may not be the Cruilla or the Arenal Soundbut on a large scale what is at stake is not only what the companies can bill food trucks. What is relevant is something deeper: in an environment where excess was part of the festival attraction, a model is now beginning to prevail where control, especially of the body and image, redefines spaces designed for the opposite. Ozempic and the end of hunger The impact of this medication is such that we are no longer talking about a health phenomenon, but rather a cultural phenomenon. What began as a diabetes medication, later converted into a weight loss solution, is no longer the beauty secret of the celebrities. The pharmacological equivalent of “drinking a lot of water and sleeping eight hours” has spread with universal consumption, and with this it not only transforms bodies with their corresponding physical consequencesalso behaviors. What began as a resource for the elite is now heading towards a more affordable distribution and on a large scale. Because we are not talking about a diet, but about something much more radical, deactivating one of the most basic impulses of human behavior on a large scale, and the data begins to reflect that change. At a global level, about 46 million of people already use these medications. In the United States, the number of people without diabetes who start treatment with these drugs has grown more than 700% in just four years. Today, around 12% of adults use them, with annual growth close to 30%. This impact does not remain only in the body and, if we transfer it to the context at hand, we see that it is directly reflected in consumption; These users spend 31% less on food and drink, especially on everything associated with whim and impulse (snacks, chocolate, etc.). In Spain the trend points in the same direction, approximately 6% of households are already consumers of these treatments, thus representing an expense of 5.4 billion euros annually in food and beverages. And, again, the most relevant thing is not what you spend, but on what: this hedonistic consumption falls and basic and functional products increase. With these numbers it is logical that the conversation of “surely he has lost weight thanks to Ozempic” does not die, but it is no longer limited to celebrities like Oprah, Kelly Clarkson or the native Ibai Llanos. The same statement now slips and extends to much closer environments such as the office, the … Read more

Spain has been without an essential weapon for war for years. Airbus has found the solution in Seville, and fires torpedoes and sonobuoys

by

One of the most outlandish ideas of World War II was to convert old B-17 bombers into giant loaded drones. with almost ten tons of explosives. The pilots would take off, activate the remote control system and parachute before the plane continued toward its target without a crew. The project it was a failurebut it left a curious lesson: finding submarines and destroying hidden targets has always required the development of some of the strangest and most advanced technologies of each era. The capacity that Spain lost. Modern warfare still relies on highly sophisticated technologies, but some capabilities remain as essential as they were decades ago. One of them is the surveillance and pursuit of submarines. Spain lost that tool in December 2022 with the withdrawal of veterans P-3 Orionleaving a void that was especially striking for a country with thousands of kilometers of coastline, a strategic position between the Atlantic and the Mediterranean and intense naval activity in its waters. Since then, the Armed Forces have lacked an aircraft capable of locating, tracking and attacking enemy submarines, a situation that is now beginning to be resolved. thanks to a program developed entirely in Seville. Cockpit of the new maritime patrol C295 The answer comes from Andalusia. Airbus advances in the construction of the new C295 MPAa version specifically designed to return to the Air and Space Army a capability that had been missing for years. The program has already passed several important industrial milestones, including powering up systems and commissioning the engines of the first aircraft. The company ensures that the deadlines remain as planned and that flight tests will last for more than a year before the delivery of the first unit in 2028. Beyond a simple replacement, Airbus considers this development the most ambitious project carried out on the C295 platform and aspires to turn it into an international reference within maritime patrol. View of the interior of the warehouse from the airplane ramp The return of the submarine chaser. The characteristic that distinguishes this aircraft from the rest of the C295 versions is its ability to combat underwater threats. The device will be able to carry between two and four Mk46 or Mk54 torpedoes and deploy up to sixty sonobuoys, small floating sensors that listen to sounds underwater and allow hidden submarines to be located. The combination of both systems returns to Spain a fundamental tool for contemporary naval warfare. For years, the country has lacked a platform capable of searching for submarines at great distances, classifying them, tracking their movements and, if necessary, attacking them. The new plane recovers precisely that function, one of the more complex and strategic within any modern air force. An arsenal of sensors. Anti-submarine warfare depends on both sensors and weapons. Precisely for this reason, the C295 MPA will incorporate a very extensive set of specialized equipment. Among them are synthetic aperture radarselectro-optical systems, magnetic anomaly detectors capable of perceiving the presence of large metallic masses underwater, automatic vessel identification systems and an advanced acoustic system to process information collected by sonobuoys. Added to this are self-protection equipment against missiles, encrypted satellite communications and tactical data links that will allow information to be shared in real time with other naval and air units. An industrial project. Although Airbus leads the program, development has also become in a shop window of the Spanish defense industry. Companies such as Indra, SAES and Tecnobit participate by providing self-protection systems, acoustic sensors and encryption equipment. The contract also includes simulators, infrastructure, training and logistical support, consolidating a technological ecosystem that goes far beyond the manufacture of the aircraft itself and reinforces Seville’s role as one of the main military aeronautical centers in Europe. Much more than a new plane. The acquisition of eight devices of maritime surveillance and eight of maritime patrol is part of an investment greater than the 1.7 billion eurosto which other contracts for new versions of the C295 have been added. The program reflects the extent to which Spain is rebuilding capabilities considered essential in an international context where submarines once again play a leading role. In essence, the history of new C295 MPA It is not just about a plane that has just come off a Sevillian assembly line, but rather about how a country that had lost one of the most important tools to control its seas is recovering the ability to find invisible threats underwater and respond to them with its own means.

Spain already experienced it between 1900 and 1912

by

Many people in the world have never seen a solar eclipsedespite There are usually between 2 and 5 in a year. The reason is that yes, they are relatively common; But, unlike the lunar eclipse, which is seen in all places where it is night at that time, the solar eclipse is seen in a very small strip of territory. In general, They usually spend between 300 and 400 years for an eclipse to repeat itself in the same place. Therefore, that In 2026, 2027 and 2028 there will be three solar eclipses visible from Spain is most peculiar. It is true that not all of them will be total, since the third will be annular, and that they will not be seen from the same points in the country, but, even so, it is something rare. Now, just because it is rare does not mean that it is impossible, since in mainland Spain we already had another trio of eclipses a little over a century ago. The first was in 1900, the second in 1905 and the third in 1912. They were not three consecutive years, as will happen with this Iberian trio, but they were very close dates for what is usually normal. May 28, 1900: a total solar eclipse that left the railway without tickets The first of these solar eclipses took place on May 28, 1900with the onset of totality at 14:53 UTC. The strip of totality, in which the complete occultation of the Sun could be seen, measured 70 kilometers wide and It extended from the north of Extremadura to Elche. Although there was still a lot of superstition surrounding eclipses, they were already beginning to be seen as something positive and, above all, as a spectacle worth experiencing. For this reason, thousands of people traveled to the locations of the strip of totality to witness it. The strip of totality was from the north of Extremadura to Elche Two of the most visited places were Plasencia and Navalmoral de la Matain Cáceres. This last town was the one that attracted the largest audience, with more than 4,000 railway tickets sold from Madrid. The influx was so great that when the tickets were sold out it was decided to release another edition, with a 25% increase in price. Still, many people bought them. Nobody wanted to miss this event that attracted scientists from Spain, England, France and Ireland. In Spain, the photographs taken by Manuel Gil, a science professor at the Central University of Madrid (the current Complutense University) stood out. There was great media coverage and many anecdoteslike those who said that the bees revolutionized, the sheep bleated uncontrollably and the storks returned to their nests. Night fell shortly after noon and this baffled the animals and fascinated the humans. August 30, 1905, the eclipse that ended religious prejudices Although in 1900 religious prejudices were slowly beginning to be put aside, they were still quite present. However, possibly the fact of seeing a solar eclipse and the world not ending led to the 1905 eclipse being received much more calmly among the general population. Totality, which began at 13:03 UTC on August 30, was observed in a strip from the north of Galicia to the north of the Valencian Community, passing through Castilla y León and Aragón. It lasted more than 3 minutes in some of these locations. Specifically, The center of the strip was in the town of Quintanillain Burgos, although the places where it was best seen were Burgos capital and the Leonese town of Cistierna. Unfortunately, the weather was not the best, so there were many places where the clouds They prevented the viewing of the eclipse. Despite that, this total solar eclipse had great media and scientific coverage, with astronomers from all over Europe meeting mostly in Burgos and León. April 17, 1912, a peculiar eclipse The solar eclipse of April 17, 1912 It was quite peculiarbecause it was a mixed annular-total eclipse. There was a very small strip of totality, just a few meters long, in northwest Spain. Furthermore, that totality lasted only a few seconds, so very few people were able to see it. On the other hand, annularity was seen in a larger area of ​​land, from Porto to Gijón. During an annular eclipse it is not night, but rather the Moon hides the center of the Sun, which is seen as a kind of bright disk. It attracted the attention of many astronomers, both Spanish and French, who gathered mostly in the Leonese town of Cacabelos. However, being so short, it did not attract as much of the general population and much less the press, which was busy with international news such as the sinking of the famous Titanic. October 2, 1959: the Canary Islands It is often said that 1912 was the last total solar eclipse in Spain. However, this is an unfair statement, since in 1959 one took place in the Canary Islandswhich also attracted a lot of national and international press and scientists. Totality occurred from 9:26 UTC and could be seen in La Orotava, Santa Úrsula, La Victoria, La Matanza, Tegueste, La Laguna, Santa Cruz de Tenerife, el Rosario and Arafo in Tenerife, Las Palmas Santa Brígida, Ingenio, Telde and San Bartolomé de Tirajana in Gran Canaria and the Jandía area in Fuerteventura. That was the last total solar eclipse in Spain, but only until now. Soon we will be able to enjoy one more. And then another. And another one. How can we not be excited, releasing one news item after another? It is a very special period.

You thought you ended up liking beer out of habit. Science has seen many ways to acquire this taste

by

There are many people who cannot stand certain foods, such as the hated broccoli or cauliflower, which for some is inedible and they do not even understand how someone could like that. This also happens when you first take a sip of coffee or a drink of beer whose strong flavor can put anyone off. However, a few years later, that same bitter drink is part of the daily routine or even a pleasure, as is the case with beer. How is it possible? This is the question we can ask ourselves about these sudden changes in taste, and the truth is that it is quite documented under the term “acquired taste“. These two words explain not only why our preferences change, but also how our brain is capable of rewriting its own danger alerts to transform rejection into a reward. Survive. To understand why we learn to love certain flavors, we first have to understand why we hate them in the first place. Much of the blame lies with food neophobia, which is nothing more than the fear or refusal to try new foods, since although in childhood we usually label it as “being picky”, from an evolutionary point of view it is a sophisticated defense mechanism. If we look back to prehistory, children put anything they found in their mouths; like a new berry or a bitter plant, they were very likely to end up poisoned. That is why any bitter taste for our brain is a sign of toxicity and, therefore, we must reject it. Although this is not the case, as is the case with many foods. It’s genetic. The interesting thing is that this rejection is programmed from the factory and has a very strong genetic component. This has been seen in studies done on twins who demonstrated that childhood food neophobia is highly heritable, estimating that heritability by up to 72% during early stages. This genetic predisposition is often associated with a lower acceptance of diverse flavors and textures, and a more restrictive diet in childhood. But genetics only deals the cards with which we will later play in a great environment, since 28% of the probabilities leave a margin for environmental factors. Hacking the brain. The question here is that if biology has programmed us to spit out coffee because it is bitter… Why are many people hooked on it? The answer lies in the brain mechanisms of flavor learning and memory, since our brain constantly evaluates the post-ingestion consequences of what we eat. This is what explains, for example, that if we vomit a lot after eating a tortilla, we begin to put it aside later because we associate it with illness. But if we drink something bitter and, instead of getting sick or dying, we get a boost of energy like with caffeine or a social disinhibition like with alcohol, the brain updates its database and points out that the risk was worth it and that we achieved something positive. Repeated exposure. In order to introduce new foods into a diet that is being developed, as occurs in children, science suggests that Consistency destroys this disgust that generates. However, visual exposure alone is not enough to break this ‘phobia’, rather repeated oral contact is necessary for the nervous system to adapt and accept the food. To facilitate this process, humans have thought of techniques such as, for example, sweeten foodand that is why the fact of adding sugar to coffee or drinking it with milk arises. This acts as a neuropsychological bridge to signal to the brain that these are safe calories. The social model It is one of the most important tools to intervene in our tastes. Here studies in infants suggest that seeing parents enjoy an unfamiliar food significantly increases acceptance in babies. And the reasoning is quite simple, since if the adult eats it and does not suffer damage, the food is considered safe to continue eating. And as you grow up, a large part of the flavors acquired in adolescence, such as beer or traditional dishes, are adopted because they are strongly linked to contexts of socialization and group acceptance, since if a friend takes it and nothing happens to him, it is because everything is fine.

the shadow business that moves VTCs in Spain

by

Before the boom of Uber and Cabify, the acronym VTC They were an enigma. Now they have become almost a popular nickname. In Madrid, it is enough to see the sticker of the red flag with stars of the autonomous community on a car to think “it is a VTC”. The urban center is littered with this type of vehicles. But the VTCs, which respond to “transport vehicles with driver“, existed for decades. They were cars intended for luxury transportation, the typical car that was rented with a driver. These actors are still in the market and operate in the tourism sector or as transportation for companies, but they are a minority. Apps changed everything. Cabify, Uber and Bolt have taken VTCs out of their niche to bring them to a mass audience. Thanks to the immediacy they allow, these cars with drivers have become so close to the taxi figure that they now constitute direct competition. But unlike taxi drivers, who tend to be small self-employed, a large part of the VTCs are in the hands of large companies. And they do not correspond exactly to the apps. “There are three large groups, which are Moove Cars, Auro and Vecttor,” says José María Cazallas, Secretary of Organization of the Free Transport Union, which represents around 80% of the workers in the VTC sector and also has significant representation in the taxi sector. “These three groups come together more or less around the 60% of licenses VTC in Madrid.” They are different entities from the applications that the user knows, although Cabify and Uber have participation in these companies. VTCs vs taxis The rise of VTCs in Spain cannot be understood without taxis and the framework in which they traditionally operated. “The model of one license for each taxi driver was followed. It was a very interventionist model. I’m talking about the beginning of the 20th century until the end of the 90s, in which they tried to distribute the business,” explains Alejandro Román, professor in the Department of Law at the University of Seville and author of the book The legal regime for the transport of passengers on demand in tourist vehicles (Taxis and VTC). Román affirms that for a long time the granting of licenses was contaminated by the clientelism. In times where well-paid work was scarce and there were many arduous jobs, a taxi license was a safe option. “These people had a guaranteed job, with a guaranteed profitability, because they had no competition,” says the professor from the University of Seville. “The number of operators in the market was calculated so that all license holders could live reasonably well.” (Unsplash) In a limited market, which barely issued new licenses, these became a scarce commodity. Their buying and selling occurred at astronomical prices. But the panorama changed completely with the arrival of Cabify and Uber. License prices fellalthough later it has come back. Now, in a look on Wallapop you can see taxi licenses for sale for between 180,000 and 210,000 euros for Madrid. In Barcelona they have a similar price, slightly less than 200,000, although some advertisements exceed them. It depends on the schedule for which the license is scheduled or if the car is included. The history of VTC licenses is different: their price has not stopped growing and they have reached almost the same level. Again taking Wallapop as a quick barometer, you can see that a VTC license in Madrid is available for around 180,000 euros. In Barcelona, ​​where the sector faces regulatory uncertainty, the price is much lower, around 75,000 euros. But the most important change that Cabify, Uber and Bolt have brought is technological mediation. “In the VTC the model is different. What happens is that over time it has become increasingly closer to the taxi model,” says Román. The VTCs could not take clients on the street or at taxi stops, while the contracting of their services had to be done in advance. This is established by law to guarantee a market reserve for taxis, which in return are obliged to perform certain public functions, such as not rejecting clients or providing transportation support in situations of health emergencies. “With the arrival of applications, this required pre-contracting is diluted. The technology itself makes it immediate. Because you open the application, you pre-contract the VTC, but you can start using it five minutes later,” concludes Román. In practice, the two models provide the same type of transportation service, although they have different regulations. A sector of large companies The similarity of the service they provide, however, differs in their back room. The exploitation of VTCs is dominated by large companies with hundreds or thousands of licenses in their name. These companies are intertwined with some of the platforms. “Cabify is the owner of Vecttor. And Moove Cars and the Auro Group are owned by Uber,” says Cazallas, from the Free Transport Union. “While the number of licenses that each taxi driver can have is limited, in the case of VTCs there is no limitation on the number of licenses per owner. That is why a market of large companies that request many licenses has emerged,” emphasizes Román. And the number continues to increase. Cabify has deployed in Madrid 800 new licensespart of a package of 8,500 requested in 2018 taking advantage of a legal loophole. (Unsplash) The Estonian platform Bolt, the only one of the three that does not have its own fleet and claims to work with freelancers and small businesses, criticized the granting of these licenses as a form of market concentration. According to their calculations, the addition of 8,500 licenses to the Cabify/Vecttor fleet would put 70% of the active VTCs in the autonomous community under the control of a single company. One of the main figures behind Vecttor has been the Sevillian businessman Rosauro Varofounder of PepePhone. He built a VTC company that accumulated 2,000 licenses for later sell it to Cabifybecoming part of its shareholders. … Read more

Cold War spy satellites

Ander Izaguirre is the author of Return to the country of Elkano. It is a book that mixes travel chronicle with adventure narration. The story begins in Guetaria, where he returns after touring the Basque country by bicycle, taking as the backbone of history the figure of Juan Sebastián Elcano, considered the first person to complete a complete circumnavigation of the world. An idea is repeated several times in the book: the world has always been much more connected than we think. The starting point, in this case, is something that happened more than 500 years ago. What could the life of a person who crossed the planet five centuries ago be like when there are still people today who do not go beyond the borders of their country or their hometown? In its pages it talks about the connections between empires and geopolitical struggles to control trade routes. Sometimes, it is difficult to understand how in those days a person could travel thousands of kilometers and metropolises could trade with each other. But, personally, I find it much more complicated to imagine JUlius Caesar traveling along the Nile or Cleopatra living in Rome on the edge of the new year count with its Julian calendar. We are talking about a handful of years prior to the supposed birth of Jesus of Nazareth. Imagine if we go back further. As much as 4,000 years. That is, around the year 2,000 BC In two leaps we have begun to ask ourselves how our world could be interconnected just 500 years ago to how it would be more than 4,000 years ago. And to that question, some archaeologists believe they have found an answer. A river highway in Mesopotamia And our colleagues Motorpassion They bring us the story of one of those discoveries that will delight history fans. For many years it has been known that mesopotamian cities They have been using an intricate system of tunnels and water management for their irrigation for thousands of years. The invention was so effective that by adding all the conduits that have been active at some point, it is believed that it may have the same distance as there is between the Earth and the Moon, according to National Geographic. These tunnels were used, as we say, to move water from the Tigris and Euphrates rivers but also to serve as a refuge for the inhabitants of these cities, both from the scorching heat of the desert and from possible enemy invasions. This has been, until last year, what was thought. And using spy images and the use of LiDAR, research has continued to advance until making sense of a new use of these channels. According to the researchers who have developed Identifying the preserved network of irrigation canals in the Eridu region, southern Mesopotamia, published by the University of Cambridge, These canals would also serve as a river highway to trade between towns. In the 1960s, the United States launched a spy satellite project called CROWN. These satellites took photographs of the terrain in the middle of the Cold War and the declassified file has allowed researchers to detect subtle changes in the terrain that are impossible to detect from the ground. The photographs revealed small differences in the vegetation, which shows commercial roads and passenger traffic for millennia. But using LiDAR, researchers have also managed to bring to light some cities that were hidden, as was the case of an extension near Abarkuh where those famous canals were discovered. The great discovery, however, has been to verify that these canals were not only used to transport water through complex hydraulic systems or to cool the environment. Everything indicates according to the latter research which were also used to move goods, resources and wealth between city-states such as Ur, Uruk, Lagash or Eridu. With this discovery, it is considered that we are facing one of the oldest and most extensive logistics networks in history and the key to understanding how grain, copper, wood or precious stones were traded then thanks to flat-bottomed ships that would move through these canals and not only through the visible bed of the Tigris and Euphrates.

They are suffering from delusions of grandeur

by

Aaron Levie, founder and CEO of Box, has realized something: AI is causing some managers to suffer a certain disconnection from real work and believe that AI does things that in reality (for now) can’t do. for him it’s clear that what the CEOs of technology companies are experiencing is an “AI psychosis.” AI myths and realities. This year we are experiencing frenetic movements in the technology industry. Stock market valuations of technology companies skyrocket, but at the same time Mass layoffs accelerate. There seems to be an explanation gaining momentum in Silicon Valley: those in charge of technology companies are suffering from what Levie calls “AI psychosis.” There are in these moments some cognitive disconnectionand CEOs and senior officials believe that AI can do tasks today that in reality still require being under human control and expert judgment. There is a long way from saying to doing. According to the CEO of Box, managers are sensitive to this “delirium” because “they are sufficiently removed from that last stretch in which the work is done.” That is to say: a CEO sees a prototype of an AI model that generates a contract or a line of code and believes that is enough to declare that the work is done. However, it is not these managers who have to review that code in search of flaws or analyze contracts in search of misleading or false clauses that the AI ​​has invented. 100x Organizations. There is a particularly surprising case in this area. Zeb Evans, CEO of the project management startup ClickUp, recently said in X that had laid off almost a quarter of its employees after deploying 3,000 AI agents to do their job. According to him, the human employees who have remained in the company simply have to supervise the machines, forming what Evans called a “100x organization.” What the CEO sees vs. what he should see. The triumphalist messages of some companies and CEOs like Evans can be quickly contrasted with the data we have today. The decisions being made – for example, in the area of ​​layoffs that are often hidden behind the adoption of AI – should be based in improved productivity which at the moment does not exist. Some studies made it clear: A study from the University of California at Berkeley evaluated several investigations in this regard and concluded that “there is no robust relationship between the adoption of AI and an aggregate productivity gain.” Other investigation of the National Bureau of Economic Research (NBER) indicated that AI had indeed improved productivity, but found “a productivity paradox, whereby perceived productivity gains are greater than measured productivity gains.” Finally, MIT researchers They created thousands of agents to work on various tasks and concluded that in many cases they did not perform those tasks with human quality. According to their estimates, AI models will be able to complete many tasks “with 80-95% success in 2029 with adequate quality,” but they will not yet surpass human workers. The new bottleneck. The danger of this “psychosis” is that by automating the production of content or code the problem does not disappear. It just moves. If everyone uses AI to produce more things, the bottleneck is precisely the managers who must manage and control the review of a volume of data that did not exist before. It is in fact just what Harvard Business Review denounced in a recent analysis. Levie made it clear: CEOs must “go down into the mud” and see what AI can and cannot do, because otherwise what they will end up having is true organizational chaos.
