Samsung already has its own smart glasses. The difficult thing will be to differentiate them from those of their competitors.

by

During the Galaxy Unpacked event held these days in London, Samsung has presented your long-awaited smart glasses. We are looking at two different designs developed in collaboration with the international eyewear brands Gentle Monster and Warby Parker. The glasses combine a light frame and a thin but resistant profile. The goal: to be able to wear them without problems throughout the day. It is a proposal that, yes, will have to compete with an increasingly lively sector and in which differentiating is beginning to be problematic. Before continuing, we remind you that the members of Xataka Xtra can access discounts, benefits and exclusive opportunities in the Samsung online storein addition to exclusive raffles, a private Discord server and a growing catalog of discounts and advantages on digital services. You can join the community for only 30 euros per year. Smart glasses that hide their ability Won-Joon Choi, COO of Samsung Electronics’ Mobile eXperience (MX) business, explained in the presentation that AI is also transforming mobile experiences, adding that “smart glasses create a new point of interaction and bring more personalized AI assistance.” The smart glasses from Samsung’s Galaxy family boast a particularly light and comfortable design, but without compromising the battery. This has an autonomy of up to nine hours with a single charge. The charging case allows for up to seven additional full charges. In that frame, the glasses include an integrated camera that provides visual context to the AI ​​experience. An exterior and interior LED indicator inform when recording is active, while recording is automatically deactivated when the glasses are removed from the user’s face or when the exterior LED is covered. Additionally, users have additional controls over privacy and personalization, and their audio, screen sharing, and video data is not used to train artificial intelligence models. And as the center of that experience, a Snapdragon AR1 Gen 1 chip which is responsible for providing the necessary performance for all the functions offered. Among others, this SoC is responsible for solving touch interaction, connectivity, energy efficiency and thermal management. During Galaxy Unpacked, Samsung presented two different designs, developed together with Gentle Monster and Warby Parker. The Gentle Monster edition features a slim black frame that combines a straight top line with gently rounded bottom edges. The Warby Parker design presents a slightly raised top line in brown, a proposal that until now had not been seen so much in this type of wearables. In the press presentation we saw a third model with an equally differential design in which the frame had more oval and narrower lenses. Gemini by flag The other main protagonist of the user experience on this device is GeminiGoogle’s generative AI model that thus provides an assistant with which to interact by voice in a natural, immediate and intuitive way. Not only can we ask for help and assistance about what we see at all times, but we can also use it as a voice assistant to chat and ask questions of all kinds. Some of these use cases stand out at Samsung. Some work in collaboration with our mobile, for example summarizing long messages, translating in real time or reading information aloud. It is also possible to use the location to find a route, and the camera can also be used as an interface for Gemini to explain how to complete a manual task. Price and variants of Samsung smart glasses At the moment, Samsung has not provided information on the price or availability of these smart glasses, but we will update this information as soon as it is available.

Japan has been charging a 0% tariff on foreign cars for half a century. It will be very difficult for you to find one on the street.

by

Japan is a fascinating country, one of those that is difficult to understand from the point of view of a Westerner. Perhaps because we ourselves have turned our backs on Asian culture during our years of teaching or because, simply, they have historical and cultural particularities that are difficult for us to assimilate. What is certain is that the Japanese have deep roots in the consumption of local products. It must be taken into account that Japanese society is deeply nationalisticperhaps because it is surrounded by other countries where this feeling is also deeply rooted, such as China or the Koreas, which has caused continuous tensions in the area. After the Second World Warthe United States financed the recovery of Japan, with the clear objective of putting a geopolitical plug on the communism that threatened from China and Korea. A movement that could have diluted this nationalist sentiment. Little by little, the country grew and in the 70s it managed to diversify its industry and, at the same time, apply technical innovations that placed it at the global forefront in many sectors. Taking advantage of the weakness of the yen against the dollar, they decided to put all their efforts into export as much of your products as possible. Those exports flooded the world economy with products. One of the most significant were cars. In its technical innovations, the country prioritized the efficiency of its engines, key to flooding the market when the oil crisis. Compared to American and European cars, The Japanese were cheaper and consumed less. It was at that moment that the industry completely exploded and Japan decided to make a decision: it lifted tariffs on foreign cars. Come and see Japanese politicians must have thought something like this in 1978. In order to be more competitive in foreign markets, the country lifted all tariffs for those who wanted to import a car into their country. That is, any foreign brand could sell its cars in Japan without paying a single extra euro. In Japan they should not have any fear of what was going to happen. Its industry was so powerful and the cultural factors were so determining that foreign vehicles have not fully penetrated the market. For testing, In 2016 the European Union lifted the 10% tariff with which it taxed Japanese cars. The 3% that Japanese manufacturers paid for producing in Europe but using Japanese parts was also raised. In exchange, the European Union found the door open to sell other products, such as cheese or wine. So, the European Union came from buying 575,000 cars from Japan worth 9,000 million euros while we only sold them 279,000 vehicles worth 7,300 million euros, they collected in The World. From here we can get two readings. The European Union, a specialist in car exports, had only placed 279,000 cars in Japan in a market in which Almost five million units were sold in 2016. Of the 12 best-selling brands that year in the country, only one (Mercedes in tenth position) was foreign. And none of the 30 best-selling cars in the country were foreign. The cars that the European Union managed to place in Japan were high-priced vehicles. The average unit cost Japan more than 26,000 euros while those purchased by the European Union cost less than 16,000 euros. That is to say, it was difficult for Europe (and very difficult) to compete by volume. When Japan opened its doors to the world, it had to be aware of the country’s particularities. Tough emissions and space regulations have made cars disappear from the center of large cities. Since the 60s is applied in the country Shako Shomeishothe obligation to have a space where you can park your car to have the right to buy a car. In a country that is concentrated in cities, the limitation is decisive. Furthermore, the Japanese customer fully trusts their companies and finds it difficult to open up to new technologies. The reception of the hybrid car compared to any other technology (and the resistance of the Japanese firms themselves to the electric car) is a good example of this. To this we must add that, due to price, the large generalists cannot compete since local vehicles are much cheaper, taking advantage of the fact that production within the country is more competitive. The value of the yen, lower than the dollar, euro or pound, allows them to obtain large amounts of money for the development and manufacturing of a product that allows them to lower prices in their local market. On the contrary, foreign companies that have to sell there face a cut market due to emissions regulations, the barrier of space regulations and that they have the obligation to change the production of the car since when driving on the left they need to position the controls on the opposite side. An added cost that creates another obstacle. The result is that we Europeans and Americans end up offering Japan cars that are not interesting. In Japan, minivans and cars are a religion. kei carcontained on the outside and with a very large interior space. A type of car that has disappeared in Europe while in Japan the Toyota Sienta, the Nissan Note and the Honda Freed occupied the places of third, fourth and fifth best-selling car in the country. And you can continue down the list of 20 best-selling cars in Japan in 2025. You won’t find a single one that is foreign. And, by the way, 13 of them are from Toyota.

Making a robotic hand is “100 times more difficult” than building the entire robot. These Chinese companies are determined to solve it

by

China has achieved let your humanoid robots run, they fight and even that execute choreographies with astonishing precision. That was the easy part. The key for a humanoid to stop being a fairground attraction and become a useful product is not in its legs, balance or its “brain”, but in something much smaller and much more complicated than it seems: the hands. The challenge of the hands. The human hand has 27 bones, 34 muscles and countless nerve endings. Replicating this in metal and circuits is the biggest bottleneck facing modern robotics. sums it up well Guardian Zhou Yong, founder of LinkerBot, one of the most advanced Chinese startups in this field: manufacturing a robotic hand is “a hundred times more difficult” than manufacturing an entire humanoid. “The dexterity required by a hand is ten times greater than that of any other part of the body, but its volume is only one-tenth the volume,” Zhou says. That is, not only is it the most technically complex element, it is also the smallest. The Chinese advantage. Pan Yunzhe, founder of Wuji Technology, studied in the United States and considered setting up his robotic hands company there, but soon saw that it was unviable. He tells The Guardian that “It was practically impossible to manufacture hardware in the United States due to the enormous limitations of the supply chain.” And China has an unmatched supply chain: it is agile, it is sophisticated and, above all, it is cheaper. This gives them a key advantage in hardware and allows companies like Linkerbot to already manufacture 5,000 robotic hands per month, a figure impossible to match anywhere else in the world. The problem is the software. Making the hand is only half the job, you also have to make it move like a human hand and there is still a long way to go here. Nathan Lepora, professor of robotics and AI at the University of Bristol, sums it up: “the challenge of making these hands is already being solved,” but controlling them “is a completely different game… no one knows how to do it yet.” The scarcity of data is one of the big problems and it is that, while LLMs have been trained with the enormous amounts of data on the Internet, there is hardly any data on how a human hand moves and, above all, what it feels like when touching something. To try to overcome this obstacle, Wuji Technology is testing a glove packed with sensors that captures all the movements of the human hand in everyday tasks. Its founder admits that being able to capture “how a person moves and what they touch or feel” is an “extremely complex and unsolved” task. The robotics market. The Chinese robotic hands sector had a turnover of $7.4 billion last year, almost four times more than in 2024. LinkerBot, one of the leading startups, aspires to a valuation of $6 billion. The case of this startup is just one example of the robotics boom in China, where more than a million companies are already registered, 40% more than last year. This translates into brutal dominance: China already manufactures 90% of the world’s humanoid robots and it is the country with the most industrial robotsby much difference with the rest. Yes, but. Robotics is advancing by leaps and bounds, but there are voices calling for calm, and not just any voice, but that of the International Federation of Robotics. In your report published in September last year were clear: “True multipurpose humanoids are still far away.” We are going to continue seeing more and more amazing demonstrations, but from there until they are sold en masse and we can all have one at home that is truly capable, there is a way to go.

Tesla wanted to have its autonomous driving system throughout Europe this summer. Sweden just made it very difficult for them

by

The famous supervised autonomous driving system of Tesla (FSD) has crossed the Atlantic and is already preparing to circulate on European roads. However, the strategy does not seem to be going as well as the company would have liked, since it has run into regulators again. In this case, Sweden and its speed limits. Below these lines we tell you all the details. Arrival in Europe. It all started last April, when the Dutch traffic authority (RDW) approved the use of FSD in the Netherlandsbecoming the first European country to give the green light to the system. Since then, Belgium, Denmark, Lithuania and Estonia have followed suit with national approvals of their own. Tesla needed to gain traction in this way in its first European countries and that is what it has done. Now the next step is to obtain approval valid for the entire European bloc. And that’s more complicated than it seems. For FSD to circulate legally throughout the EU, the Technical Committee for Motor Vehicles (TCMV) you should vote for it with a qualified majority, with at least 15 of the 27 member states representing 65% of the community population. The committee is scheduled to meet June 30 to discuss the matter before a formal vote. Speed ​​limit. FSD includes a function called “Speed ​​Offset” that allows the driver to set a margin above the legal speed limit, so that the system itself drives exceeding that limit. In the United States, Tesla offered this under names like ‘Sloth’ or ‘Mad Max’. In Europe, those profiles have disappearedbut the possibility of exceeding the limit is still there under another name. Who says no, and why. The Swedish Transport Administration (TRV) sent a letter to the TCMV in April recommending voting against the FSD expansion if Tesla does not remove that feature. According to the document, obtained by Reuters“allowing automated systems to systematically exceed legal speed limits poses risks that undermine both the legal framework and the expected benefits of vehicle automation.” Finland and Norway have also been skeptical of the introduction of the system in their countries, although they have not yet formalized their position before the committee. What Tesla answers. The company has not commented publicly on the matter, but its user manual points out that drivers should not rely solely on the system to comply with speed limits and that they should drive “at a safe speed based on traffic and road conditions.” Their implicit argument is that FSD is a supervised system, as the driver remains responsible and can take control at any time. For Estonia, this reasoning has been sufficient to approve the system at the national levelalthough the country has not yet defined its vote in the TCMV. There is more at stake than speed. Various regulators have questioned also the performance of the system in extreme conditions with heavy snow (something common in Nordic countries) and the name “Full Self-Driving” itself, which could be misleading about the real level of autonomy of the vehicle. In fact, the European version already shows “FSD (Supervised)” on the screen instead of the full name, precisely to reduce that ambiguity. Additionally, Reuters public A few days ago, Tesla reportedly presented questionable safety data to European regulators, including the claim that FSD could have “saved 32,000 lives,” something that has not caught on, at least according to share Electrek. What is at stake Tesla. Tesla sales in Europe have plummeted significantly since 2025partly due to the impact of Elon Musk’s fleeting political activity, and the flood of new Chinese brands that have disrupted the sector. In fact, BYD has been outperforming him in registrations for several consecutive months. Tesla needs new arguments to regain ground, and FSD was one of them. Musk even publicly predicted that It would be available throughout the EU this summer. At the moment it seems difficult to achieve.

“It is very difficult for a worker to reach 67 years of age in full capacity”

by

The vast majority of employees over 63 have something in common: they can’t wait to retire. However, with each passing year, retirement seems a little further away. In reality, it is not a perception, but it’s a reality which has been occurring since 2011, when the regulations were approved that delay the retirement age by a few months each year. Alfonso Muñoz Cuenca, Social Security official specialized in pensions, counted from her YouTube channel the case of an acquaintance who was 65 years old and had 25 years of contributions who couldn’t wait to retire. For the expert, this feeling is the symptom of a problem that is repeated more and more as they harden retirement requirements: There are people who reach the final stretch of their working life without the real ability to sustain the pace required of them. Age increases, but the body does not always accompany. As and as highlighted Trendsthe Social Security reform of 2011 established in the Law 27/2011 established the progressive delay of the retirement age, while the requirements to access it were also increased. In 2026, only those people who can prove a minimum of 38 years and 3 months of contributions will be able to retire at age 65. Whoever has not paid for that time will have to wait until the 66 years and 10 months to retire. The current pension system was designed in a very different social and health context, in which workers lived an average of seven years after retiring. According to INE data Today life expectancy exceeds 20 years on average after retiring. However, the fact that life expectancy is longer does not mean that the most veterans reach the end of their working life in full physical condition to meet the demands of the position, which makes the latter especially hard for them. Burnout does not always have a diagnosis. Muñoz Cuenca summarizes it in his video, stating that “there are workers who can barely reach the age of 67 standing on a scaffold, or doing endless shifts in a hospital without rest.” The problem is that this wear and tear rarely appears in a medical report. There is no declared disability, but rather accumulated fatigue, loss of rhythm and a body that no longer responds the same who did it when he was 40 or 50 years old. The burnout data in Spain collected by Unobravo confirm that 55% have suffered total exhaustion at some point. The health sector and care professions are those most affected by this situationwith sectors with chronic staff shortages and high workloads. He UGT report of 2025 He adds that job insecurity increases the probability of developing depression by 61%. The exhaustion of employees in the last years of their working career that Muñoz Cuenca describes has, apparently, a lot of statistical support. The problem of the years listed. In his video, the expert comments on the case of a 65 and a half year old worker who wants to retire, but only accumulates 25 years of contributions, which closes the doors to early retirement. Just to have the chance to access early retirement On a voluntary basis, you need to have contributed for at least 35 years. Whoever does not reach those figures has few options. Muñoz Account says that, after a career marked by the precariousness of temporary contracts, the years dedicated to caring for her children, not adding these minimums is more common than it seems. He Labor Market Report for those over 45 in 2026 Prepared by the Occupations Observatory, there are more than eleven million people over 45 years of age employed or affiliated with Social Security, more than half of the total. Many arrived late to the labor market or have accumulated careers with many bumps, which makes them serious candidates for not meeting the minimum requirements to access retirement at age 65. Partial retirement as an escape valve. Muñoz Cuenca proposes what he calls “work slowdown”: reducing the workload progressively as the end of active life approaches. Not as a new right, but as a change of mentality in companies to facilitate generational change. The legal tool already exists in the form of partial retirement with relief contract. From 2025, you can apply up to three years before the ordinary age, with a minimum of 33 years of contributions. This mechanism allows the employee’s working hours to be reduced by between 25% and 75%, and collect part of the pension, while the company hires someone to cover the remaining hours and train them to take their place when retirement is final. However, far from being the norm, this type of progressive retirements They are the exception since not all companies are obliged to accept it, so the employee has no choice but to force the machine beyond its capabilities, resulting in an increase of 43% in the number of leave among employees between 55 and 65 years old. Gina Aran, human resources consultant, confirmed in an interview for The Vanguard that “retirement should be one’s own choice, made judiciously, taking into account the state of health, and insists that it should not be something abrupt and obligatory.” In Xataka | Social Security has published the data on sick leave in 2024 and we have bad news: we have broken a record Image | Unsplash (Sweet Life)

some experts fear consequences that are difficult to measure

by

There is an initiative to build a gigantic data center in Utah (USA). The so-called Stratos Project plans to occupy an area equivalent to the city of Washington DC and is estimated to consume 9 GW of power. Some experts warn that the thermal impact will be devastatingand they claim that “it is the equivalent of releasing the energy of 23 atomic bombs a day in the form of heat.” A Dantesque project. The approval of Project Stratos occurred at the beginning of May by the Box Elder County Commissionersthe community in northwest Utah on whose land it will be located. The megacomplex plans to occupy 16,100 hectares of surface, and if completed it will become the largest data center on the planet. That record is disturbing and alarming. 9 GW of computing capacity. This data center will consume 9 gigawatts of power, a figure that doubles the current electricity consumption of the entire state of Utah. The figure, like all those surrounding the project, is absolutely exaggerated, and there are many those who have criticized the project. But also GW of heat. The biggest concern for experts It’s not just energy consumptionbut how this will affect the temperatures of the region in which this data center is intended to be built. Robert Davies, a physics professor at Arizona State University, has made the first calculations on this impact and his conclusions are worrying. Because the natural gas plants that will generate electricity for the center are 57% efficient, the complex will produce about 7 or 8 GW of waste heat. Once that electricity reaches the servers, it will be converted into heat, and it is estimated that Project Stratos will emit about 16 GW of thermal energy daily in the Hansel Valley where it will theoretically be located. 23 atomic bombs. Davies points out that this release of heat in a closed basin like the one in this valley is equivalent to “depositing the energy of 23 atomic bombs every day in the local environment.” It is obvious that the project does not generate nuclear explosions or radiation, but it will cause notable climate change. The models estimate that daytime temperatures will increase by 2.7 ºC on average, but the nighttime ones will suffer peaks of up to additional 15.5ºC. The semi-arid climate of the region, one of the driest in the US, will transform into an area with thermal dynamics similar to those of the Sahara Desert. Threat to Great Salt Lake. The location chosen to locate this AI data center is not coincidental: the Hansel Valley is the area through which the so-called Ruby Pipeline passes, a gas pipeline that transports natural gas from Wyoming to the west coast of the United States. The problem is that it is also very close to the northern end of the Great Salt Lake, a body of water that has already been in danger for some time. In fact, its water levels are near historic lows after an unusually dry winter. we were few. The supply contracts indicate an even greater risk to that body of water. The developers plan to acquire local water rights equivalent to about 16 million cubic meters. It is a volume sufficient to cover the basic needs of more than 20,000 homes in Utah. Data center hate is real. This is the latest and most notable case of mega data center construction projects that trigger frontal rejection from local communities in the US. While AI companies and hyperscalers continue to announce new data center construction projects, residents of these areas organize local resistance.

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.

The machines were already beating us at chess and Go. Now they are about to beat us at something much more difficult: ping pong

by

Human beings have a curious relationship with machines: we create them to help us, but also to challenge us. We have been doing it for decades, from large industrial systems to artificial intelligence systems and robots that today begin to move in more complex environmentsmore demanding and with less margin for error. And when those machines surpass us, we don’t just see a defeat: we see a clue as to where the technology is going. It already happened in chess and Go. What we are seeing now points to something different: the challenge begins to jump to sports where it is not enough to calculate the next play. The robot that plays ping pong. The last signal comes from Sony AI and is shaped like a ping pong table. Your Ace robot, developed within Project Acehas been presented by the company as the first AI system capable of competing in a real physical environment with elite university players and table tennis professionals under official rules. The firm illustrates this with a recent scene in Tokyo: Japanese professional player Taira Mayuka launched a shot that, under normal conditions, would have decided the point. On the other side of the net, Ace read the trajectory, adjusted the angle of the paddle and returned the ball to keep the exchange alive. A notable jump. Ping pong adds something much less friendly than table games: a ball that moves, spins, bounces and changes direction in a very short time. That’s why Sony insists on Ace’s reaction speed, with an end-to-end latency of 20.2 milliseconds compared to about 230 milliseconds in elite human players. As we can see in the video that accompanies this article, the robot not only has to “see” the ball. You have to anticipate what he will do next and get the paddle at the right angle before it’s too late. How do you get it? The key is that Ace does not depend on a single technology, but on a very tight chain between perception, control and movement. The system integrates nine synchronized conventional cameras and three event-based vision systems, capable of recording movement changes very quickly. With that set, the robot tracks the ball at 200 Hz with millimeter precision and measures the effect up to 700 Hz. An eight-degree-of-freedom robotic arm then executes the returns based on policies learned through reinforcement learning in simulation. Ace didn’t get to that point overnight either. Sony places the start of the project in 2020, within the first works of Sony AI, and describes an evolution in stages: first juggling the ball, then maintaining cooperative exchanges with a person and, later, facing increasingly stronger players. This journey also served to discover limits that do not always appear in a simulation. The limits. Ace’s merit lies in having reached an expert level, not in having turned table tennis into a solved problem. Sony recognizes that there are still humans above the system. In any case, the robot mainly excels in skill, where you decide how to move the robot and how to hit the ball in real time. What happens point to point, and what is planned during a match, can still improve.

It seemed difficult for China to compete with the US as a global tourism power. And yet it’s happening

by

Although tempers have cooled after the war in Iran and the doubts about what impact it will have on the sector, in general international tourism is experiencing its ‘roaring 20s’. Families have come out of the pandemic break wanting to pack their bags and get to know new countries, something that has not taken long to be noticed by the UN tourism observatory, which last year registered an increase of 4% in the flow of international travel, as in the World Travel and Tourism Council (WTTC), which estimates that the sector represents almost 10% of global GDP. The increase, however, has not been equally strong around the world. What’s more, WTTC itself has noted important differences in the two large economies of the sector, the US and China, which could precipitate a surprise historical. I like to travel. The world has emerged from the pandemic with a desire to travel. Many. It is a trend that has already been noted in 2024when pre-COVID levels were recovered, and has continued to consolidate over time, which explains, for example, that Spain is bordering on the historical barrier of the 100 million travelers a year or that Japan gives clear samples of saturation. According to the latest calculations of the WTTC, 2025 was “the best year in history for the sector”, at least as far as economic growth is concerned. Its contribution to world GDP exceeded 10.7 billion eurosabout 10% of the global economy, and supported almost one in ten jobs worldwide. These are compelling data not only because of their scope, but also because of the trend they show: in general the tourism sector is growing more than the international economy. The US slows down. The ‘photo’ is not, however, equally good in everyone. The WTTC technicians have noticed a weight loss in the main economy tourism on the planet, the American one. Although the country governed by Trump remains “the largest travel and tourism market in the world”, the truth is that it is losing market share. The data is resounding: while the sector grew at 4.1% overall, in North America that percentage was four times lower (1%). In fact, it was the “slowest growing region in the world.” The balance was even worse in the US, with an increase of 0.9%. A key fact: 5.5%. “In 2025, eighty million more people took international trips compared to the previous year, although they chose other destinations. The number of American visitors decreased by 5.5% compared to 2024 and spending by international visitors decreased by 4.6%, reaching $176 billion,” they point out those responsible for the WTTC. His analysis joins others that in recent months have warned of a setback in the flow of foreign tourists arriving in the US and the loss of attractiveness in key markets. For example, the country’s Department of Commerce registered in 2025 a drop of 20.9% at the entrance of visitors from Canada. In 2024 it had already registered a decline, but of only 1.3%. Why is it important? For what it means for the American tourism industry. And for its implications in the sector worldwide. As the WTTC reminds us, today the US continues to be the economy that more money moves thanks to tourism and travel, with a notable advantage over the second On the list, China: the US moves at 2.63 trillion dollars while the Asian giant is around 1.75 trillion. How has the US achieved that weight in the sector? Thanks to two legs: the local market, the trips that Americans make when traveling from one city or state to another, and the arrival of foreign visitors. If we look at the latest reports from the US Travel Association and the WTTC, the first leg continues to respond well. In 2025, Americans they accounted for 87% of the country’s tourism business and increased their contribution to the sector. Their spending was 14.3% higher than pre-pandemic levels. Things change, however, when we look at the arrival of tourists from other countries: their flow was reduced by around 2.3% and their spending indicators are also not good when compared to those the country managed before COVID. Losing “hook”. This loss of attractiveness among foreigners coincides with a hardening of the conditions to enter the US and news about arrests in airports, which even led some European embassies to give guidelines to its citizens to avoid surprises with their visas. Another key factor was the international policy deployed by the White House, which strained relations with countries such as Canada and Denmark. The decisions made by the Trump administration soon gave rise to campaigns that advocated boycotting American products, something that was felt in tourism. In January WTTC itself warned Washington that if it finally approved the new requirements it had on the table for ESTA authorization applicants, which included a thorough review of tourists’ online activity, it risked losing just over a third of its visitors. “34% of those surveyed say they are less likely to visit the United States in the next two or three years if the changes are implemented,” he warned. China on the prowl. It is not just that the US sees its market share in international tourism shrink, it is that everything indicates that China will take advantage of this situation to cut positions. “While the US contracts, China grows at a dizzying pace,” explains Gloria Guevarapresident and CEO of WTTC to Bloomberg. “If this continues, in three or four years it will reach the US.” In another interview A recent interview with USA Today even went further and warned that, if the current situation continues, China will end up “replacing” the US as the world’s main tourist market in a matter of four years. today the gap Between both markets it is enormous (the US sector contributes 2.63 trillion dollars and the Chinese 1.75), but Beijing is growing at high speed. WTTC estimates that its tourism sector is growing at a rate of 9.9% and that, unlike what … Read more

AI is making it increasingly difficult to know what is real and what is not. And child sexual predators are taking note

by

The era of artificial intelligence is making everything happen very quickly, very quickly. Companies like Mercadona, Google or Anthropic already point out that the vast majority of your code is written by an AI, Mozilla flowers Mythos and Jensen Huang is excited about the benefits of AI and everything that allows us to create. Among these creations there is everything, such as an enormous amount of child sexual abuse material. Researchers ask for help, and I can tell you that there are things that are not easy to assimilate. In short. This Wednesday, Bloomberg published a report that condenses six months of research in which they focused on the rapid proliferation of child sexual abuse material generated by artificial intelligence. It is not something that is surprising if we take into account the enormous amount of false information that we already have to deal with every day both in text form and in increasingly realistic images and even on videobut there is an important nuance. While in the case of the fake news It is the press and the people who must deal with it with common sense so as not to swallow the hoax, wasting time in the process. In the case of this content generated by AI, it is the police and investigators who must waste their time to rule out that it is true information. And, while they are doing that, they stop investigating cases of child sexual abuse, other types of abuse or disappearances that are real. The figures. They are scary, of course. The report points out that the National Center for Missing and Exploited Children received more than 1.5 million reports during 2025 that had a general generative intelligence component. Among them, more than 7,000 reports about users generating or possessing child sexual abuse material generated with AI and more than 30,000 cases of people generating this type of content. It’s stupid. On the other hand, the IWF (Internet Watch Foundation) evaluated more than 8,000 AI-generated images and videos that very realistically depicted acts of child sexual abuse. There were 3,443 videos compared to the 13 registered in 2024. In total, an increase of 26.385%. The growth is important and the IWF itself pointed out in the report that 65% of this video content generated by AI shows events classified as ‘Category A’, the most serious within this type of material. Cases. Do not think that they are cases of dark websince AI chatbots have been discovered on the open web that host these images and encourage them to be created. What type of content are we talking about? Here comes the delicate part. Bloomberg points out some examples that are part of those thousands of more complex cases that are currently being processed by the authorities and where there is… everything. A man who used the faces of children in his neighborhood to generate content with them having sexual relations with their mothers or grandmothers, another who produced sadistic images of small children and babies, another man accused of altering the image of a prepubescent girl to enlarge her breast and posting the images on Onlyfansa priest who spent years collecting material and then created even more thanks to AI or an army soldier who sexualized images of children he knew with AI. Where do the images of children come from?. Facebook and Instagram. That’s the simple answer. According to Joe O’Barr, one of the researchers who lent a voice to the Bloomberg investigation, “people steal images from Facebook and Instagram, things that parents freely post, and They post them on artificial intelligence platforms”. One pattern that has been discovered is that many create images involving children they know in the real world, thus fulfilling their fantasies. For example, a case of a man who took photos of his partner’s six-year-old daughter, manipulated them with AI and then posted them next to his own naked images on Onlyfans. “The fact that the perpetrator knew the victim made my hair stand on end. It meant that the girl could be in real and imminent danger” – Joe O’Barr What platforms do. Those same platforms on which the images are hosted do not sit idly by. Researchers trust that those same companies will raise the alarm when they find something, but there is a problem: Google, xAI, Meta or OnlyFans are delegating the monitoring task to AI. Numerous cases have been reported of humans who can’t stand flagging that type of content and that is why they either hire in countries like Kenya, or they directly delegate to AI. The problem is the number of false positives that the AI ​​finds and that end up overloading the researchers’ ‘mailbox’. A North Carolina investigator notes that he has seen an 11-fold increase in those ‘tips’ his office receives, and last year alone the volume doubled to 52,000 reports. He points out that any human would say “this is not content to investigate”, but since the AI ​​does not know this, it sends everything: from serious things to investigate to simple insults. Unbearable. “The more cases we have to investigate, the more difficult it is to treat each case individually,” says one of the researchers. Meta itself has recognized that its system is not perfect and adds “some noise” to the researchers’ network. As we said before, it is an enormous amount of material that prevents investigators from doing their work in real cases of minors who are being abused or who are missing. “We are doing this massive job with the same amount of resources we had ten years ago. We can’t take it anymore and we don’t want to miss a real child who is being sexually abused,” an agent tells Bloomberg. Legislators, get your act together. The work of these investigators depends on the Department of Justice and funding that consists of about $30 million for 61 state task forces. They point out that it is a very small figure and, to put … Read more
