Gasoline hoses have a tiny hole at the end. Without chips involved, it is the smartest piece in the entire supplier

by

If you’ve ever paid attention to the pump while filling up, you may have noticed that it has a small hole located near the tip of the metal nozzle. That little hole is, possibly, the most ingenious piece of the entire set. And it is responsible for the hose “knowing” when to stop adding fuel and stopping on its own with that characteristic click. What exactly is it. This small hole is located at the end of the pipe (the part that you insert into the tank) and is connected to a thin, secondary tube that runs inside the nozzle parallel to the main fuel line. The nozzle uses the fuel itself that is being pumped to create the effect that activates the automatic cut. So to speak, the little hole does not pour gasoline, but rather breathes air. How it works. The key is in a physical principle called the Venturi effect. While the fuel flows at high speed through a narrowing of the duct, a low pressure zone is generated that sucks air through that small hole in the tip. The Venturi effect occurs because The density of gasoline is greater than that of airand it is precisely this phenomenon that causes the dispenser to turn off automatically when the tank is full. The moment of cutting. When the gasoline level inside the tank rises to cover that hole, the tube stops being able to suck in air. When the airflow is cut off, the suction is triggered and creates a vacuum that pulls on a flexible membrane (a diaphragm) housed in the handle of the nozzle. That movement releases a lever mechanism that slams the main valve shut, stopping fuel instantly. The pressure change causes the diaphragm to “jump”releasing the mechanical lever that closes the valve and ending with a click. And as you may have already noticed, the cut occurs even if you continue to pull the trigger. 100% mechanical. This entire system is purely mechanical. There are no electronic sensors, no chips, no batteries. The handle simply generates a slight vacuum at the tip of the pipe, and if that point becomes clogged, a mechanism closes the valve. It is basic physics applied to this little invention that we use in our routine, and that is capable of detecting even a small amount of fuel, blocking the hole to prevent it from overflowing. Security and cuts. This system prevents gasoline from overflowing from the tank, something that would be dangerous (risk of fire) and polluting. But its usefulness goes beyond safe filling. This extraordinary sensitivity is also the cause of those premature and repeated cuts when the jet turns off even though the tank is not full. The most common cause of these annoying cuts is simply a little gasoline splashing back and covers the hole momentarily, activating the mechanism ahead of time. In cars with short filler tubes, a rapid flow can easily flood that column, so the first recommended remedy is usually to reduce the filling rate. The position of the nozzle and the temperature of the fuel also play a role. In Xataka | The United States has the best electric car chargers in the world. Europe has something more important

Pancreatic cancer was almost invincible. A new targeted therapy just doubled survival

by

Pancreatic cancer has been, for decades, one of the biggest challenges of modern oncology. Its diagnosis usually arrives late and therapeutic options in advanced stages have historically been limited, accompanying a mortality very high. But a new experimental drug has hit the table by promising to double survival in patients who have the most severe forms of the disease. The protagonist of this revolution is called daraxonrasib and has come to light together with the data recently presented at the American Society of Clinical Oncology congress that has shaken the medical community, confirming that we are facing a possible paradigm shift for a disease that had not received good news for too long. More months. To understand the magnitude of the advance, you have to look at the results of the phase 3 trial, called RASolute 302. This study has focused on patients with metastatic pancreatic ductal adenocarcinoma who had already received previous treatments without success. Until now, the standard therapy, which is the well-known chemotherapy, in this second line of treatment offered a median overall survival of just 6.7 months. But it has been seen that, when administering daraxonrasibthe median overall survival shot up to 13.2 months. That is, practically double. And there is more. The trial, considered the first large phase three study of a drug of this type in this context, not only demonstrated an improvement in lifespan, but also in disease progression-free survival and in the objective response rate of tumors. The endorsement Although it may seem very promising and fanciful, we are seeing that this therapy is based on a scientific basis that had already been audited and published at the highest level. By this we refer to the published results of the previous phases of this trial that were public in The New England analyzing 168 previously treated patients, and a powerful antitumor activity was seen. But it is not without problems, since the NEJM article detailed that about a third of patients experienced significant adverse effects. However, in the context of metastatic pancreatic cancer, the risk-benefit balance is considered extraordinarily promising. An invincible enemy. The real technical triumph of daraxonrasib is its mechanism of action, since pancreatic cancer is known to be largely driven by mutations in the RAS gene family, and especially KRAS. And for more than 30 years, the scientific community considered that proteins mutated by KRAS were impossible to medicate. But now daraxonrasib is a multi-RAS inhibitor that acts on the mutations of this very specific protein that were the gateway to pancreatic cancer. This makes it the first pancreatic targeted therapy capable of offering sustained responses over time. The Spanish accent. The arrival at phase 3 does not mean that the research ends here, but rather that the scientific community is already looking for a way to enhance this drug with other drugs to prevent the tumor from ‘learning’ to endure it. In this field of preclinical biology, the work of Spanish researchers stands out. The group of the prestigious scientist Mariano Barbacid has already documented work in animal models using a triple combination that includes daraxonrasib along with other drugs that have been on many people’s lips recently.

Mexico wanted to end telephone anonymity. SIMs are already being sold with someone else’s identity on the black market

by

He Mexican government made the decision to end the anonymity of cell lines and thus put an end to telephone extortion. The goal is for each number to be linked to a person by June 30; after that date, all unregistered lines will be disconnected. The problem is that on the black market there is already a way to circumvent this rule. What is happening. They tell it in Xataka Mexico following a newspaper investigation Millennium. In the historic center of CDMX anyone can buy a SIM card already activated under the identity of another person, without having to leave their personal data. It costs 200 pesos and can be done in minutes. He modus operandi. The official process To register a mobile line, you must provide your identification document or passport and perform biometric identification using a selfie video. The sellers of these SIMs take a photo of the barcode on the card and send it via WhatsApp. In a few moments, the fraudulent registration is done and they even offer a guarantee if there is a problem. All for 200 pesos: 100 pesos for the SIM and 100 pesos for the procedure. A striking detail is that the majority of SIMs sold with this method are from Movistar. Deepfakes. Although it is not clear how registration is carried out, it has already been confirmed that the identification system is not infallible. As reported in The Countrythe system cannot distinguish between a real person or a deepfake made with AI, so registration can be done on behalf of anyone simply by having their data and a photo. False lines have even been registered using the senator’s data Gerardo Fernández Norona. Fear of identity theft. There is another problem with line logging related to trust. Many citizens flee from the registry for fear that their personal data will end up on the black market. It is not an unfounded fear, it is something that already happened in a previous attempt to create a database with mobile phones in 2008. The initiative was called Renaut and ended up being eliminated in 2011 after complete databases were leaked and sold on the black market. Later, in 2022, the Supreme Court invalidated another attempt because it considered it violated the right to privacy. Massive line losses. This distrust has had an impact on telephone companies’ numbers. Many prepaid users have preferred to let their lines die rather than comply with this obligation. Taking into account that in Mexico more than 80% of the market is prepaid, this translates into massive line losses. In the first quarter of the year, AT&T Mexico lost a whopping 577,000 lines, while Telcel lost 483,000. With contract users there is not so much resistance since when signing with the operator the personal data has already been delivered. An unreal goal. The government is putting pressure with advertising campaigns to get registration done before the deadline, but it does not seem realistic that they will achieve it. As of May 19, there were registered 49.5 million lineswhich represents 30.7% of the total, which is about 160 million lines. As we said, if the plan continues as planned, all lines that have not been registered before June 30 will be disconnected.

Why do prices go up if sales go down?

by

The real estate market has started 2026 with a strange ‘photo’ that, a priori, seems to contradict the most basic laws of the market: sales fallbut prices go up. Or what is the same, thousands of fewer operations are closed in notary offices than a year ago without this apparent cooling in demand being passed on to prices, which continue to grow at the same time. double digit after saying goodbye to last year with historical data. The question in view of this duo trend is evident: What is happening? And above all, what can we expect now? Fewer homes sold. Although winter is not the time of year more dynamic For the real estate sector, the first quarter of 2026 has left a curious image: despite how tense the market is and that homes continue to be created at much more speed of which new homes are built, in Spain there are fewer houses changing hands. The purchase and sale operations chained three months downward during the start of 2026, which explains why the INE registered a 2.6% decline in the first quarter. The number: 4,713. To be precise, the INE registered 61,295 transactions of homes throughout March, 2.2% less than during the same month in 2025. If we talk about new constructions, the decline was even more pronounced: 10.2% (5.3%, if we talk about the entire quarter). In general, the aggregate for the year (January-March) is 178,473 purchases, 4,713 less than in the equivalent period of 2025. The ‘photo’ of the marketOf course, it is not the same throughout the territory. There were eight regions in which March closed with more transactions than last year, with Castilla-La Mancha in the lead; but in eight others (including some of the most populated) the trend was the opposite. In Madrid the INE recorded 2.5% fewer purchases and sales, in Catalonia the decline was 3.5% and in Andalusia 6.5%. The largest falls were recorded in the Basque Country (-11.6%) and Cantabria (-15.4%). The INE is not the only one to detect the setback. In March, the Notarial Council also registered a 4.7% puncture in transactions, more pronounced in the case of apartments. And the prices? They point in the opposite direction. He latest newsletter from the Ministry of Housing on appraisals shows that, in general, free housing became more expensive during the first quarter of the year until the residential square meter (m2) stood at 2,315.7 euros. For reference, it is 3.8% more than the previous quarter and 13.9% above what was paid a year before. In new housing, less than five years old, the increase compared to 2025 was 12.8% and in used housing (more than five years old) 13.8%. Once again, the trend was also felt in the offices of notaries. In it same statement in which it notes a general drop of 4.7% in sales in March, the sector reports a 7% rise in the cost of m2. Its balance sheet shows this apparent dissonance even more clearly: apartment transactions fell by 5.8% compared to March 2025, while prices rose by 9.7% to reach €2,332/m2; In the case of single-family homes, operations contracted by 1.1% while the cost rose by 2.2%. Year (1st quarter) Free housing (€/m2) less than five years More than five years 2020 1,640.4 1,891.5 1,632.5 2021 1,625.4 1,879.3 1,617.5 2022 1,734.0 1,980.9 1,726.7 2023 1,788.4 2,112.1 1,778.1 2024 1,865.8 2,199.3 1,855.8 2025 2,033.4 2,357.3 2,024.1 2026 2,315.7 2,685.2 2,303.8 But… Why? The first thing is to take perspective. The market may be stepping on the brakes with respect to 2025, but it continues to move at high levels if we analyze what the sector has managed since the setback that followed the brick crisis of 2008. That is, the 61,295 transactions in March may be less than those of 2025, but they are still well above the 44,664 of 2024. In fact, a year ago we were at record values that have not been seen since 2007. It is an important nuance because it shows that the drop in sales in the first quarter of 2026, as much as it may attract attention, seems to point more to a gradual slowdown than a sudden turn or change in cycle. The market gives signs, true, but they come after 2025 that closed with more than 700,000 salesthe highest figure in almost 20 years, since the bursting of the brick bubble. He last balance from the INE also shows that purchases do not suffer throughout the territory. In fact, there are regions, such as Castilla-La Mancha, Navarra, La Rioja or the Valencian Community, Galicia or Asturias, where they have grown. And the prices? Not everything is uphill. There are those who also appreciate some restraint. A recent study by Idealista shows, for example, that in the first quarter 14% of homes for sale they had to lower their price. During the same period in 2025 that percentage was 11%. Other reports specify that, beyond the general ‘photo’ provided by the Ministry of Housing, there are cities (including some capitals) in which prices have moderated. something moves. The above helps to put things into perspective, but it does not mean that the residential market is not changing. confirms it in theEconomist José García Montalvo, expert at the Pompeu Fabra University: “The slowdown in sales is one more example of a trend that is corroborated by the increase in sales time, the growing disparity between the prices that sellers want to receive and the growing limitations of buyers due to the difficulty of obtaining credits of the necessary amount for homes whose price has grown rapidly.” Ángel Talavera, from Oxford Economics, launches another reflection in elDiario: “When prices begin to rise uncoupled from rising incomes, it is likely that purchases will slow down.” The truth is that the cost of housing itself partly explains the slowdown in sales. Rentals, for example, they continue to get more expensive. And while this makes the purchase more attractive, it also … Read more

The Chinese brand that sells the most cars in Europe decides on Spain

by

MG will manufacture cars in Spain. It is official after weeks of rumors in which we had been hearing that the Spanish region was one of the best positioned to produce cars from the Chinese firm of British origin. It is its first major investment outside China in almost a decade and, without a doubt, an endorsement of its European plans. The advertisement. MG has confirmed it: Galicia is the region chosen for the return to MG manufacturing in Europe. The announcement had been advanced by Alfonso Ruedapresident of the Xunta, this morning but it was not until this afternoon when the MG herself confirmed the news. For months it has been known that the Xunta de Galicia has been in talks with the Chinese brand to settle on Spanish soil for its new arrival in Europe. And in April, Rueda himself held a series of meetings with representatives of the brand between April 23 and 25 in China, according to The Automotive Tribune. The project. The company assures that, from the outset, the project has an investment of 200 million euros and that it will create “more than 2,000 jobs in Europe, establishing a strategic center for the next phase of MG’s growth.” That is, the press release provided by the company does not specify how many of these jobs will be in Spain and how many will be created by the increase in cars in the European market. The company assures that this new plant is scheduled to come into operation in 2028 and that it will have an annual capacity to manufacture up to 120,000 vehicles. At the moment, it has not been confirmed what types of vehicles will be manufactured (pure combustion, hybrid or electric) nor have the models been specified. For its part, in information collected by The Worldthe Xunta raises the figure to 2,300 jobs, of which 1,000 would be direct, another 1,000 indirect and 300 would be related to the company’s activity in As Pontes (a town near Ferrol). In this location, the company is expected to build a components plant. Some doubts. For now, what is known is that the company will establish itself in Ferrol and build an auxiliary plant in As Pontes. The choice of Ferrol is determined by its port, which has already served as a gateway for other Chinese manufacturers for sale in Spain or subsequent distribution throughout Europe. What has not been confirmed, in addition to the type of vehicle used, is what manufacturing method will be carried out. The Chery Group in Barcelona uses the DKD method where the local impact is minimal. The companies (Omoda/Jaecoo/Ebro) have repeated that they will increase the number of operations that will be carried out in Barcelona but, for the moment, the cars arrive semi-assembled in containers and on Spanish soil only the last pieces of the puzzle are being put together. At the moment, in its information SAIC (owner of MG) does not refer to whether the cars will arrive more or less assembled on Spanish soil. The more processes that need to be carried out in the Spanish plant, the more direct jobs and the more work will be given to auxiliary companies in the area. “In Europe, for Europe”. That is, according to MG, the maximum of this landing in Galicia. And the company has found a vein in our continent with the sale of cars with all kinds of technologies at very low prices. In Europe it is the Chinese brand that sells the most carsplacing in 2025 a total of 211,014 units in the European Union and 305,717 units if we put the Nordic countries and the United Kingdom into the equation. These sales are understood because the SAIC Group has found in MG a vein to sell cheaply in Europe. The brand, previously British, is not unknown to the public and both its hybrids and electric ones are cheap compared to traditional European proposals. In Spain, so far this year, the MG ZS is among the 10 best-selling non-plug-in hybrids and is the sixth best-selling car in the sum of all technologies, according to ANFAC data. Furthermore, the brand is the tenth best-selling company in our country. Duty. It remains to be known, as we said, what the bet is in terms of specific models but it is clear that the landing of Chinese brands such as BYD in Hungary and Turkey or the Chery Group in Barcelona is directly associated with the implementation of European tariffs on Chinese electric cars. SAIC, which owns MG, is the company facing the highest tariffs. Manufacturing in Europe may allow them to compete, even more, on price, but the European Union has already made it clear that it will be necessary to make a minimum number of investments to consider that the car is European. This does not mean that the car is electric. Although cars with combustion engines do not have tariffs, rumors point to greater European shielding of their economy. And producing in Europe for Europe can help, even more, to lower the price of cars with combustion engines, partially alleviating the economic effort that the company has to make with electric cars.

35 billion dollars to build the largest airport in the world

by

95,192,160 passengers. This is the number of travelers who registered at Dubai International Airport (DXB) in 2025, according to data from Airports Council International (ACI). A figure that elevated it to second place in the world for passenger traffic, only behind Hartsfield-Jackson Atlanta International Airport in the United States. This last location has been repeating for three years asThe busiest airport in the world and last year it moved 10 million more passengers than Dubai, breaking the barrier of 106 million passengers in a single year. A figure that, year after year, Dubai wants to reduce to become the airport with the highest passenger traffic in the world. And it has a $35 billion plan to achieve it. An airport like no one ever conceived As we said, so far Dubai has remained below 100 million passengers per year. However, the ambition is to break this barrier in just two years. Paul Griffiths, CEO of Dubai Airports, assured Time Out that they aspired to break this ceiling soon and that by 2031 they want to reach 113 million passengers. These figures would predictably make them the busiest airport in the world but it has a problem: the current Dubai International Airport (DXB) and remodeling it would cost as much money who, directly, prefer to get a new one. At least that is what they maintain from the Emirate. And in 2010 the Al Maktoum International Airporta space that until now has operated at half throttle and is a ridiculous size compared to its Dubai brother. But in 2024 an expansion was approved to position it as the largest airport in the world with the capacity to handle 260 million passengers in a single year. That is, almost the same passengers as the three busiest airports in the world right now: adding Haneda in Tokyo (third in the world) to those mentioned in Atlanta and Dubai. According to the voices that have defended the project, the problem is that the current airport is so large that maintenance work drives up costs and, they say, it is cheaper to build a gigantic expansion of the current Al Maktoum International Airport than to renovate the famous Dubai International Airport. For this, it has been planned to invest 35,000 million euros to make the current Al Maktoum International Airport the center of the Dubai World Central (DWC), the most ambitious mobility hub in the world. This space has been planned as a megacity with residential spaces, hotels, golf courses… and, above all, the largest airport in the world built by man in its history. Specifically, has been projected that the renovation of the new airport costs $34.85 billion. This figure reflects the ambitions to multiply the size of the DBX by five, building five 4.5 kilometer long landing strips separated by 800 meters. It will have four main concourses and more than 400 doors to operate flights. The intention is that, operationally, the new airport will be operating at higher performance by the end of the decade to make the complete move from the current DBX to the renovated Al Maktoum International Airport in 2032. That year they hope to manage the traffic of 150 million passengers in one year. That is, about 44 million more passengers than the current Atlanta airport, the busiest in the world, handles. These passengers will be distributed across three terminals. The intention is that one of them is dedicated solely to the operations of the Emirates Group and another to international flights. The third will concentrate low-cost flights. In addition, a parking lot with 100,000 spaces is planned for workers only. The intention is to build a high-speed train between both airspaces but to transfer the bulk of the operations to the new construction. Of course, its surroundings and all its services are not expected to be built until 2050. By then, Dubai intends to be able to operate flights with the capacity to move up to 260 million passengers. That is, it should be able to manage half the population of the European Union in a single year. To consolidate this mega-move, the Dubai airport is already working with new biometric recognition and baggage management systems using artificial intelligence as a test before the airlines arrive at the new space. Obviously, the intention is scale operations to mitigate the risk of collapse. Consolidation as the largest mobility hub in the world is not only understood with commercial flights. Dubai wants this new space to be the best place in the world for landing flights. Airbus A380the largest passenger plane in the world, but also the best place to carry out your maintenance and repair work. Likewise, it wants to consolidate itself as a key place for the transportation of goods and have restricted space for the landing and takeoff of private flights to which it will be offered all kinds of luxuries with a huge range of auxiliary services such as the aforementioned hotels, shopping centers and leisure spaces.

They have asked 1,600 experts how the Universe works. They don’t agree on almost anything

by

We continually read news about new findings that they defy the known physics of the Universe. This may lead us to ask ourselves something: do we know so little about the Universe that absolutely everything challenges it? To answer this question it is important to give a little context. Yes, a lot is known about astrophysics, but when we talk about something as immense as the Universe, even that “a lot” can fall short. Furthermore, much of this information is based on hypotheses that have been accepted as consensus, but not on absolute truths. Therefore, it is not strange that in the largest survey ever conducted It has been proven to astrophysicists and astrophysics fans that there is a lot of disagreement on almost everything related to the cosmos. The largest survey. In 2024, during an astrophysics conference in Copenhagen, a survey was carried out in which 85 experts participated. All of them had to answer a series of questions about some of the best-known theories in astrophysics. With this survey it was seen that there is a lot of disagreement, even in those theories in which there is supposed to be a great consensus. In order to check whether these disagreements were a result of the sample size, a new survey was carried out in 2025, this time with 1,600 people who had to answer 11 questions. Some participants were experts from the American Astrophysical Society. Others were amateur readers of Physics Magazine. With a larger sample, the results were very similar. There is very little consensus. From hypotheses to certainties. Science in general, and astrophysics in particular, is built on hypotheses that evolve as scientific advances are made. For this reason, it is often more full of probabilities than certainties. It is important to differentiate different branches of science. In health sciences, there are certainties. For example, we know that antibiotics attack bacteria and are not useful against viruses, no matter how many people insist on taking them for the flu. We also know that their abuse can be very harmful, since it contributes to the development of resistance in bacteria. Those are certainties, although logically there is also information that evolves over time. In astrophysics, hypotheses accepted by consensus often outnumber certainties. There are very clear certainties, such as that the Earth is not flat or that it revolves around the Sun. But also some hypotheses with which not even experts agree. Cosmic inflation wins. The issue on which there was the greatest consensus in the 2025 survey, the results of which were recently published, was cosmic inflation. That is, the hypothesis that points to an exponential expansion of the Universe which began in its first moments, after the Big Bang. 51% of respondents agreed that this theory explains many problems in cosmology at once and therefore has a high probability of being true. Talking about the Big Bang. The existence of the Big Bang was another of the theories with the greatest consensus in the survey, although the truth is that the figure is nothing to write home about either. 25% of the participants agreed that this event gave rise to the Universe 13.8 billion years ago. On the other hand, there were 68% of people who indicated that the Universe was born at a time when there was a large increase in temperature and density, but they did not indicate when that occurred. Disagreements with dark matter. Gravitational behaviors that do not respond to the observed mass have been observed in the Universe. That is, it seems as if there are massive objects exerting a gravitational attraction on others, but these objects are not detected, not even large accumulations of atoms. There is nothing. 27% of those surveyed consider that this can be explained by the existence of dark matter. However, there are 12% who believe that all this may be due to changes in the behavior of gravity on cosmic scales. That is to say, when we talk about the immensity of the Universe, the gravity exerted by objects is not the same. On the other hand, there are 5% of people who consider that the key is in primordial black holes. Although here we must emphasize that one of the hypotheses about the origin of dark matter is that it is formed in part by primordial black holes, so they would not be denying its existence. String theory to solve incompatibilities. The theory of general relativity was proposed on large, cosmic scales. On the other hand, quantum mechanics talks about the behavior of matter on a subatomic scale. Both questions seem incompatible, but to understand the Universe we need to work at both scales. Therefore, for a long time there has been thought about a theory that helps unify both issues. This, for 19% of those surveyed, is string theory. In it, subatomic particles, instead of being treated as points, are considered vibrational states of a more basic extended object, called a string. Normally, when we try to calculate the energy of a particle by considering it a mathematical point, without extension, we get closer to it eternally. We can do a kind of infinite zoom. On the other hand, when the points are replaced by strings with a minimum length, a result must necessarily be obtained. It does not tend to infinity. On the other hand, in string theory gravity, which not normally considered on a quantum scalearises naturally. Another hypothesis. The point is that, in the survey we are talking about, there are 12% of people who consider that string theory does not solve the problem, but that another theory does: that of loop quantum gravity. This, basically, acts in a completely opposite way. String theory emerges with quantum mechanics as a starting point and tries to find ways to make gravity make sense. On the other hand, the theory of loop quantum gravity starts from the General Theory of Relativity and attempts to quantize it in a way that … Read more

“They are hiring more engineers”

by

Are you a software engineer and afraid of getting fired because of AI? Well don’t have it. At least, that is the position of a very interested party in the conversation around artificial intelligence. At this point, the name of Jensen Huang It will not be foreign to you. This is the CEO of Nvidia, a company that has gone from leading the GPU segment for playing video games for two decades to leave that market for focus on AI platforms. We cannot say that they are doing badly, of course, and within the strategy we have a Jensen who has become one of the most important ‘evangelists’ in the segment of the artificial intelligence. Within the framework of the Computex 2026 fair held in Taipei and in which PC manufacturers show their new products, Jensen commented that it is foolish to be afraid that an AI will replace us at work. The logic is that this AI will generate more jobsbut there is a question hanging over that argument: what kind of jobs. Because, if the optimism of all companies focused on the development and popularization of AI is one side of the coin, the other is that of lYoung people who cannot access jobs. And that of the companies themselves firing employees to replace them with… an AI. Jensen Huang is on a mission At Computex, Huang feels at home. Taiwan is home to some of the world’s most important technology companies not so much for their products. There we have giants like Asus, BenQ, Foxconn or Acer (among many others known to gamers). But, above all, we have TSMC. TSMC is the engine of the chip industry and Nvidia its current best client after overtaking Appleand Huang, furthermore, is a rockstar in Taiwan. During his time at the fair, Huang presented his new platform RTX Spark Superchip and a new chip to compete against Intel and AMD in the field of CPUs, but it has also taken advantage of the speaker to demonstrate again your opinion on the future of AI and work. The CEO consider that AI is something positive for both GDP and everyone’s profits, but also pointed out that it is “nonsense” to think that artificial intelligence is leading to people being fired from companies in the profile of software engineers. “The number of software engineers is actually increasing. People talk about AI reducing jobs, but it’s complete nonsense: it’s leading to more software engineers being hired” – Jensen Huang Huang is very vocal on this topic and has spent 2026 taking advantage of any interview, podcast or visit to universities and events to preach about the benefits of AI and the positive relationship between technology and employment. He has gone so far as to say that “AI creates jobs” and that it is the United States’ best opportunity to reindustrialize, pointing out that blaming AI for the very numerous layoffs in industries such as technology and video games is a “too lazy” practice. Now, as in every story, there is part that is true and part that is not so true. On the one hand, Huang is very interested the narrative that AI is a job creator. As we say, it is one of the parties most interested in technology continuing to advance because we are already seeing that it is a sector that moves a lot (a lot) of money and Nvidia is one of those that is taking advantage thanks to both its products and its commercial vision. On the other hand, the reindustrialization discourse is correct. The United States is seeking that reindustrializationthis flowering of the business fabric based on technology and, to this end, it is looking not only for part of its companies to move the industry from Asia to the US, but also to attract giants like the South Korean companies. Samsung and SK Hynix…and the coveted TSMC. Does data kill story? Huang’s argument makes sense. AI creates jobs. What it doesn’t say out loud is what type of job. Because engineers or those who have careers related to the development of AI Yes, it is “easy” to get into jobs related to AI, but the rest, and profiles without much experience, find it increasingly difficult. Technology companies are getting rid of juniorswhich are replaced by AI while those jobs are taken over by developers. AND jobs are opening in record numbers of more than 67,000 offers in engineering and 7,300 in product, but the fine print is that it is almost impossible for young recent graduates to apply for one of these positions due to the high degree of specialization that companies demand. And they are not only the requirements, but the technologies themselves who are citing AI efficiency as a driver for laying off their human workforce. Amazon with 16,000 employees and Microsoft with 15,000 are two examples. Heavyweights like Dario Amodei (CEO of Anthropic) point out that AI could eliminate approximately half of entry-level jobs and there are studies that link AI with almost 55,000 layoffs in the US in 2025 alone. For Huang, all of this is “ridiculous“because it won’t be AI that will make us lose our jobs: it will be because there will be someone who uses AI better than you. Furthermore, according to himAI has created 500,000 jobs in the last two years. And, in the background, we have two currents. On the one hand, the AI ​​optimists. On the other hand, a generation Z that is actively resisting adopting artificial intelligence in their daily lives and, especially at work. Because, compared to those who think that AI is a positive network for humanity because it gives opportunities that favor young people, there are some young people who they can’t find work once they graduate, they are thrown into a disconcerting work scenario and they are starring in a curious soundtrack in recent weeks. That of the boos to the AI ​​evangelists in universities. In Xataka | Companies are … Read more
