the amazing feather trade network that existed before the Incas

by

On the arid central coast of Peru, hundreds of kilometers from the magnificent Amazon rainforest and separated by one of the most important mountain ranges in the world, archaeologists encountered something they did not expect. We are talking about a cemetery of the pre-Hispanic Ychsma culture in Pachacamac and the surprise was specifically in the funeral bundles of the elite that They were adorned with macaw and parrot feathers. that could never have survived naturally in that ecosystem. So… How did they get here? The answers. Faced with this question, archaeologists had to start thinking about it, because seeing a parrot in the middle of an arid mountain range is not the most common thing. Until then, it was believed that ancient people traded only the feathers already plucked from parrots that had been in their natural habitat. However, a new study published in Nature has revealed a much more complex and fascinating reality: the ancient Peruvians transported these live Amazonian birds through the treacherous passes of the Andes. How do you know? It is not that we have a time machine to see what specifically happened, but it is possible to analyze the ancient DNA found in these cemeteries through stable isotopes and spatial modeling of routes. In this way, the study focused on the remains found in 34 funerary bundles from Pachacamac that were dated before the expansion of the Inca Empire. This is precisely where the mummies were provided with “false heads” very well decorated with the mysterious feathers. The results. The genetic analysis in this case indicated that the extracted DNA corresponded to many species of birds that were purely Amazonian, such as the red and green macaw. But the most interesting thing comes when the isotopes are applied to the remains of the birds, because a drastic change is seen in their diet. The chemical fingerprint revealed here that these parrots were born and grew up in their natural habitat in the Amazon eating a natural diet, but in their last months of life they began to have a diet provided by humans themselves, and that did not correspond to what they ate when they were in the wild. It’s a test. This unequivocally demonstrates that the birds were not hunted for their feathers in the jungle, but captured alive, transported across the mountain range and kept in captivity on the coast to be repeatedly “plucked” or sacrificed to make the funerary goods that would end up among the elites of ancient society. It’s not easy. Crossing the Andes today is something that is not easy, which is why it was much less so a thousand years ago. In this way, through landscape models and geographic information systems, the researchers mapped the most probable routes they used from the Amazon basin to the Pacific coast. In this case, the birds had to suffer great stress with drastic changes in altitude, freezing temperatures at the highest points of the mountain and, above all, a diet to which they were not accustomed. In this way, the fact that they arrived alive at Pachacamac underlines the existence of an incredibly sophisticated animal trade network with knowledge about their care. But above all, the great value that this animal must have for the society that mobilized to bring it to its cities despite the difficulties along the way stands out. Why so much trouble? As one of the researchers points out, in the pre-Hispanic Andean world, Amazonian feathers were not a simple ornament, but rather were absolute symbols of political power, status and connection with the divine. And having access to the vibrant colors of the jungle demonstrated the elite’s control over long-distance commercial networks and gave great prestige. This discovery in Pachacamac is not an isolated case, but rather confirms a trend that archeology was already beginning to glimpse. In 2021, a study published in PNAS documented similar finds much further south, in the arid Atacama Desert, where mummies of Amazon parrots that were bred in captivity and routinely plucked were found. Now it is confirmed again. Images | Dmitry Chernyshov In Xataka | 60 years ago we discovered a Dorado hidden in the jungle of Peru. We now know that it was actually much more

There is a Chinese startup creating the most amazing robots of the moment. It’s called X Square

by

The only embodied AI (bodied artificial intelligence) company backed by the three Chinese technology giants: ByteDance, Meituan and Alibaba. Just over two years of life and financing rounds in which they have managed to overcome the 400 million dollars. These are some of the cover letters of X Square Robot, one of the most promising companies in the field of robotics. where does it come from. XSquare It is a Chinese startup which was born in 2023 at the hands of Wang Qian, an engineer and doctor from the University of Southern California who, in recent years, has maintained a discreet profile in the industry. The company was born not only as a company aimed at creating humanoid robots: they are also behind the development of the language models necessary to lead in robotics. The roadmap. The startup, despite its youth, has made the most of its two years of life. December 2023, full financing and start of operations. March 2024, efforts begin to develop a general large-scale model for embodied AIthe brain that would move its robots. May 2025, commercialization of Quanta X1, a bimanual wheeled robot equipped with its WALL-A model. Specially designed for logistics and commercial tasks. July 2025, first to show purposeful AI model general capable of directly controlling a highly dexterous robotic hand. Unlike traditional approaches—based on rules, fixed trajectories or action-specific training—the system uses a single model that integrates perception, planning and control, allowing grip and movement to be adapted in real time to changes in the environment. August 2025, Quanta X2 arrives, its first humanoid robot, also with a wheel base. The product. Quanta X2 is the latest solution from X Quare, a wheeled humanoid robot that integrates the company’s own AI model. This model allows the robot to have a vision system, autonomous motion control, real-time task planning, etc. We highly recommend watching the demo video in which X Square shows it in operation, because it is spectacular. Why is it important. X Square does not sell ordinary humanoid robots, it sells cognitive capacity. The norm in robotics companies is to design the hardware and adapt it to existing software. X Square designs its own models focused on physical AI. This is something fundamental for his native country, China. The country wants to accelerate the automobile industry in 2030 with 100% automated factories. The aid policy is especially favorable for local companies developing robotics solutions. China has created centers responsible for training robots to imitate human behavior. X Square software is key The backup. X Square is backed by giants like Alibaba and Bytedancethe first group having announced an internal team dedicated to robotics using Qwen, its AI models division, as a base. Despite Alibaba’s muscle when it comes to creating its own language models, the investment of more than $140 million in X Square Robot makes it clear that it is much more than a typical startup.

In 1976 Boston built its most amazing skyscraper. Until its windows became lethal guillotines

by

The John Hancock Tower It was conceived in the late 1960s as the great coup of authority of modern Boston: a minimalist, elegant and almost “invisible” skyscraper, designed to reflect the sky with enormous panels of lightly tinted blue glass, with reduced mullions to a minimum and without elements that would break its purity, topped by a plant that visually sharpened the corners and a vertical slit that further stylized the mass. But there was a mistake fat. The modernist dream of a glass needle. The skyscraper was the type of building I wanted seem inevitableas if it had always been there, and at the same time had to demonstrate that “corporate architecture” could be a piece of urban art. In other words, a clear aesthetic ambition was sought, but it implied an enormous risk: betting everything on glass and geometric precision, where any failure ceases to be a defect and becomes a dangerous spectacle. The first shock of reality. From the beginning, the project lived under the spotlight because it in the Back Bay neighborhood and very close of Trinity Churcha historical milestone that already had a symbolic and emotional weight in the city, and that threatened to be dominated by the shadow and presence of the new colossus. Was protests and design adjustmentsbut the real conflict soon arrived below ground: the excavation and temporary retaining walls were deformed and gave way before the mud and clay fills characteristic of the area, damaging sidewalks, services and even nearby buildings. Trinity Church ended up claiming and won a million-dollar compensationand the skyscraper, before it even existed, was already seen as a work that was too ambitious for the terrain that supported it. The glass scandal. The episode that turned the tower into a black legend of architecture occurred when it was still unfinished: with the Boston winds, the panels began to crack and fall awayand the glass fragments began to fall to the street like some kind of lethal rain. The authorities even cordoned off areas and closed streets when the wind rose, and the image of the “brilliant” building was replaced by another. much more humiliating: windows covered with plywood sheetsa partially bandaged tower in the center, which earned nicknames like “Plywood Palace” and jokes like “the tallest wooden building in the world.” In a skyscraper that was intended to represent absolute control, the failure was not only technical: it was a reputational blow direct, one where the symbol of its modernity (glass) had become a meme and a threat… Why it failed. At first you knowsuspected the wind as the main actor, of the suction and channeling effect around the building, and tests were reviewed in wind tunnels with models of the environment, but the core of the problem was in the window itself. Apparently the system it was too rigid: the reflective layer and its connection to the metal frame did not allow bending, and in a structure subjected to vibrations, oscillations and continuous thermal cycles, this lack of “play” became the breaking mechanism. The stresses were transmitted to the glass instead of being absorbed, the cracks propagated, and the result was inevitable: enormous and very heavy panels, weighing hundreds of kilos, failing repeatedly until the unthinkable was assumed in a newborn corporate icon: it was necessary to replace them all. The tower at the time the windows that had fallen out were replaced with plywood The expensive remedy. The solution It was shocking.: remove and replace the entire glazing with a more robust, tempered and heat-treated glass, in an operation that cost several million and that prolonged the ordeal for years. The project, announced with grandeur and reasonable budgets, ended up becoming a spiral of delays: the inauguration was postponed, the numbers skyrocketed and the tower went from promise to public embarrassment. Even so, mass glass replacement was the only way outbecause it was not about fixing a few defective pieces, but about correcting a façade idea that had been born with a structural fragility incompatible with the climate and real loads of Boston. The building today The final twist. And when it seemed like the worst had already happened, came the most disturbing blow: Later calculations suggested that, under certain wind patterns, the building could have a stability problem more serious than assumed, with unforeseen twists and dangerous behavior on its narrower sides. The tower also moved enough to cause dizziness to occupants in tall plants. The city discovered that the beauty of minimalism had a physical price. The answer it was double: on the one hand, install a huge damping system with tuned masses, two gigantic weights mounted with springs and shock absorbers to oppose the swaying and “return” the building to its center. On the other hand, reinforce with tons of bracing steel diagonal. It was, in essence, reengineer an icon already built so that it would continue standing with the dignity that had been promised from the first render. The paradox: from shame to object of desire. The most fascinating thing is that, after such a disastrous start, the tower ended up establishing itself as an admired piece and recognized, until receiving prestigious awards and becoming an inseparable element of the Boston skyline. As they counted then architectural experts, it was the kind of redemption that only happens when a building survives to his own crisis: the public ends up remembering its silhouette and its reflection, not the panic of the closed streets or the wooden planks covering the absent glass. The Hancock went from being a historical lesson for modern architecture (a reminder that aesthetics does not negotiate with physics) to be, precisely because it has overcome this technical hell, a work with a certain aura of resistance, almost a monument to the obsession with fixing the irreparable. One more thing. Over time, the tower maintained its place as the tallest skyscraper of New England, but its story continued to move in the practical terrain of money, tenants and identity: … Read more

The latest Stranger Things deepfake is so amazing that it shows that reality is beginning to be optional

by

This week, a Brazilian content creator named ederxavier3d published an amazing video on his Instagram account. In it they appeared several of the protagonists of the series ‘Stranger Things’ making just the gestures and expressions that he made in the lower window. He explained that he had achieved it in a simple way and thanks to the new Kling 2.6 and its characteristic Motion Control. This option allows the movements we make in a video to be transferred to any real or fictitious person, regardless of the style in which they are represented (it can be a comic book character) with an amazing result. And in the case of the Brazilian creator’s video it can be clearly seen: these videos could perfectly pass for real in almost all cases. It is true that if you look closely you can sense that something is wrong, but only because the video has been shared making it clear that it was created with AI. This video has once again awakened a debate that has been linked to this type of deepfakes for some time. Justine Moore, partner at investment firm a16z, explained that “we are not prepared for how quickly (video) production flows are going to change with AI. Some of the latest video models have immediate implications for Hollywood. Endless character swaps at negligible costs.” How the story has changed. In April 2023 we proposed a little game to all of you who read us: Would you be able to distinguish a real image from one generated by AI? At that time, AI was already achieving remarkable results—the image of the Pope with the coat proved it—but the feeling was that we could still tell whether an image had been created with an AI or not. With the video things were even clearer.because at that time AI video generation I was in diapers. Three years later things are very different, and there are several AI platforms (I see 3, Sora 2Kling, Runway) that generate videos that anyone could easily confuse without problems. Tell Will Smith. ederxavier3d’s video also demonstrates this, and in fact something unique happened with it: there were rumors that the Stranger Things characters had actually recorded those appearances and the creator had imitated their movements, and then rumors appeared that denied that this was true and that suggested that from the beginning the videos were nothing more than what they seemed: deepfakes created with AI. A priori everything would suggest that this is the case: the Kling 2.6 feature is not at all new and other platforms allow our movements and gestures – and even our voice – to be transferred to a character generated by AI. The problem is that At this point it is almost impossible to distinguish whether that person who appears on the screen is real or not. This technology is extraordinarily striking and causes that “wow effect” that AI companies so seek, but despite the creative options it offers, the risks here seem especially notable. The identity theft It is now easier to achieve than ever, and that will probably mean that we will see many more dangerous cases. It is enough to remind the employee that transferred 25 million dollars believing that the person who told him via videoconference was his real boss. It is not clear how, for example, Hollywood studios will react to this technology, but for now some are already taking action on the matter to try to protect themselves. The best example is Matthew McConaughey, who these days has “patented himself” to have one more legal resource (which we are not sure is necessary) to protect yourself against possible videos impersonating you. The implications are enormous, and we are entering an era in which something disturbing is going to happen: We will not be able to trust what we see on a screen.

We have found 76 megatraps in the Andes. It’s amazing we hadn’t done it before.

by

Beyond being an imposing mountain range, the Andes were one of the great hotbeds of civilization. In their complex networks of passageways they developed highly organized societieswith cultures such as the Caral, Chavin, Tiwanaku or Moche that preceded the powerful inca empire. The most impressive thing is that we continue to discover the secrets of these civilizations and we have just found 76 stone structures that not only represent advanced technology. They also confirm that there were authentic technical laboratories in the passageways of the Andes. In short. In a article published in the magazine Antiquity Researcher Adrián Oyaneder, an archaeologist at the University of Exeter, details how, by analyzing high-resolution satellite images belonging to a remote area of ​​the Camarones River basin, he found a series of structures that were repeated. Using images of both Sentinel-2 as of Google Earththe archaeologist combed more than 4,600 km² and found 76 ‘chacus‘. “My reaction when I saw the first chacu was to check it twice or even three times. I thought it was something unique, but as I went along I realized that they were everywhere in a quantity never before recorded in the Andes,” comment. It seems important, but… what corks are those ‘chacus’? The ‘chacus’. It is a term that comes from traditional Inca practices and, basically, they are very specific constructions. Its characteristics are: Funnel shape consisting of two long dry stone walls that converge to form a corridor that gradually narrows. Dimensions of about 150 meters long and one and a half meters high. Locations that seem strategic, since they are built on steep slopes between 2,800 and 4,200 meters above sea level. Not even if they were coffee plantations… So that? That’s the second question. They were traps. Traps for vicuñasspecifically. It is a relative of the alpacas and what the hunters did was urge the herds to move to the chacus, which with its funnel shape trapped the animals. But those traps could not be left by the hand of God, and Oyaneder continued searching until he found what he was looking for: traces of life. In the vicinity of the chacus, the archaeologist identified almost 800 small-scale settlements that consisted of several shelters built of stone and circular in shape. He estimates that they would be temporary camps, since human groups moved strategically through the highlands following the rhythm of the seasons. During the humid months in which the pass flourished, the settlers would go to the higher areas, but when these dried out, they descended, hunting vicuñas and, probably, some early form of agriculture. The estimate from Oyaneder is that some of these traps are about 6,000 years old. Implications. Finding 76 of these megatraps in one fell swoop is fascinating, but more important than the discovery is seeing how it fits into the story we knew until now. The Andes are a hostile environment and having discovered these structures implies that primitive Andean cultures had great resilience to adapt to the difficulties of the mountains. It also suggests that large-scale hunting coexisted with the development of pastoralism and agriculture in the region. Convergent evolution. It is now being analyzed whether the chacus represent the hunting systems at this scale oldest in the Andes, but something interesting is that there are parallels with structures that are thousands of kilometers away. An example, the ‘desert kites’ of Western Sahara: large ‘V’-shaped stone structures that were used to hunt gazelles or antelopes in a way very similar to that of Andean civilizations. It is curious that two civilizations without contact developed such similar megatraps, but it is not that strange and it is a phenomenon called “convergent evolution.” In any case, the discovery of these 76 structures in the Andes once again puts on the table that the 3D techniques and high-resolution satellite images make investigating remote, huge or difficult-to-access areas easier.

You thought you had an amazing connection on Tinder, but you were actually chatting with ChatGPT

by

Fuck you cat in a hare when flirting on Tinder It’s been happening since the app existed; photos taken from the perfect angle to capture a great guy, descriptions that do not fit reality or outright false information. Now we have to add one more risk: that the person with whom you have been chatting for days and having deep conversations is using ChatGPT to respond to you. Chatfishing. It is the fashionable term to define this trend. If ‘catfish’ is being deceived with a fake profile, ‘chatfish’ is when the other person uses an AI to prepare their responses and thus more easily conquer their “prey”. We don’t talk about fake profiles that are actually botsbut from real people who use a chatbot to plan their responses and seem like the perfect couple. There are even those who you have created an automation and let ChatGPT take the wheel. New disappointments. Fake profiles were already a problem on dating apps before AI, but in the age of AI it still adds another layer to distrust. In this Guardian report They tell the stories of some victims of this practice, like Rachel, who had a very deep connection with a man that only lasted while they were chatting. Upon meeting him in person he felt that he was “someone he had never spoken to.” I had been talking to ChatGPT. quite common. There are those who use the AI as a psychologist or directly to fall in love with one. Wear AI to improve a Tinder profile and even to help us flirt doesn’t sound crazy at all in the current context. How common is it? There is no way to know exactly, but the truth is that more and more news that narrates this type of situations. It is also not difficult to find posts on forums like Reddit. users sharing their experience after being ‘chatfished’, others showing your suspicions and even who admits to using ChatGPT to flirt. Laziness. Flirting on Tinder can be exhaustingis what is known as ‘dating fatigue’. Getting a match is easy compared to starting the conversation and maintaining interest on both sides. According to one survey conducted by Forbes78% of dating app users in the US felt tired of using them. Given this scenario, there are those who are choosing to automate some of these interactions to try to stand out among other profiles without having to invest a lot of time. The ‘chatfisher’ profile. In the report that we have already mentioned from The Guardian, several users who turn to AI to flirt tell their reasons. Nick sees it as a tool to improve his connection with his matches, but he assures that if he feels a connection with someone, he is the one who takes control of the conversation. There are also people, like Holly, who use it to help improve their communication skills, for example to make a message sound softer if they are upset about something. Of course there are those who use it simply to increase their matches and thus get more dates. Jamil tells how he ended up in a Discord where other men exchanged advice. The modus operandi was to ask the girl about her hobbies, favorite movies and things like that and then give it to ChatGPT so that it can “create answers that make you seem like the perfect couple.” And it seems that the method works because it ensures that he got many more appointments. Apps also use AI. At the beginning of the year, Tinder announced that it was going to implement AI to suggest possible connections to users. By answering a series of questions, the app creates a list of suggested profiles each day. If you also give access to your photo roll, the AI ​​is capable of detecting interests to refine the search. Other apps like Hinge or Bumble also have similar features, but Bumble takes it further with an AI assistant that helps you break the ice with catchy phrases. Of course, at the moment they have only enabled it in the version of the app to find friends. Cover image | Pexels 1, 2 In Xataka | Singles are fed up with Tinder.

The amazing image of the VLT that is already a history of astronomy

by

An international astronomer team has achieved what is equivalent to a cosmic ultrasound: They have obtained the first image of a giant gaseous planet In full formation process, embedded in the middle of a dust and gas disk with multiple rings. The system, called Wispit 2B, has become overnight in the perfect laboratory for Understand how the planets are bornincluding, perhaps, our own Jupiter. A photograph hunted at the best time. The discovery, published in Two simultaneous articles In The Astrophysical Journal Letters, he not only shows us the planet Wispit 2B, a giant of about five times Jupiter’s mass, but has “caught him with his hands in the dough.” They have detected it by emitting the characteristic brightness of overheated hydrogen, the definitive test that is actively attracting material from the disc that surrounds it to continue growing. And if that were not enough, there are indications of an even more massive planet. A cosmic vinyl disk. The first piece of this puzzle is provided by the Sphere instrument of Vary Large Telescope (VLT) in Chile, where the star Wispit 2, a young solar analogue (just five million years old) located about 133 light years from us was observed. What they found was spectacular: an extensive Protoplanetary disc of 380 astronomical units (UA) structured in four concentric rings, such as the grooves of a vinyl disk. The planetary formation theory predicts that the mass planets, when orbiting their star, “clean” their gravitational path, creating gaps on the gas and dust disc. And precisely, in the most prominent hole between the second and third ring, about 57 UA of its star, was a point of light: Wispit 2B. A discovery that had to confirm again. To make sure it was not a distant star in the background, the team made observations in four different moments over almost two years. The results were conclusive: the object moved next to the star, following a Keplerian orbit consisting of his position in the hole of the disc. The analysis of its brightness in different infrared wavelengths (Bands H and Ks) allowed to estimate its mass by approximately 4.9 times Jupiter’s mass. This is the first unequivocal detection of a planet on an album with multiple rings, directly confirming the interaction between the planet and the disc that forms it. A second definitive test. If the first investigation was the photo of the crime, The secondled by Laird M. Close, is the recorded video confession. Using the advanced Magao-X adaptive optical system in the Magallanes telescope, they also observed the system in a very specific wavelength: that of the H-Alpha (656.3 nm). This broadcast is an unmistakable firm of the accrection, the process by which a planet attracts gas from its surroundings. When hydrogen gas falls to the planet, it is compressed and heated to thousands of degrees, emitting a characteristic reddish glow. And WISPT 2B was shining intensely in H-Alfa. We already know its growth rate. This detection not only confirms undoubtedly that Wispit 2B is a growing protoplanet, but allowed the team to calculate at what rhythm it is collecting matter: 2.25 × 10−12 solar masses per year. It is a slow but constant rhythm, which offers us a unique window to the final stages of the formation of a gas giant. This finding makes Wispit 2B one of the very few protopoplanets (along with the celebrities PDS 70b yc) of which there is direct evidence of accretion, that is, that they grow gradually using external matter. A second planet and a mystery of inclination. The surprises do not end there. The high resolution data of the Magao-X team revealed a second candidate object much closer to the star, about 15 UA. Baptized as CC1 (Close Companion 1), this object is extremely red and its brightness is consistent with a planet about nine times Jupiter’s mass. In addition, researchers have indicated a curious statistical coincidence. Counting to Wispit 2B, there are already four systems with protoplanets detected by their H-Alpha broadcast. Surprisingly, they all have a very similar inclination with respect to our line of vision (between 37 ° and 52 °). The probability that this occurs by chance is only 1% (a 2.6σ significance). Why is Wispit 2B so important. There are several reasons behind. The first of these is that it visually demonstrates that giant giant planets can be formed at great distances from their star and that they are responsible for sculpting the holes in protoplanetary discs. But the interesting thing is that it has become a unique laboratory, since it is such a “clean” and well-defined system, it allows us to study the planet-Disco interaction with an unprecedented detail. An analogue of our past: The star is similar to our sun in his childhood, so studying Wispit 2 is like looking at a snapshot of how our own solar system could have formed. That is why the next step will be to point to Wispit 2B with the Jame Webb space telescope and the Alma Observatory. With them, you can analyze the planet’s atmosphere and analyze the chemical secrets you can hide.

Nvidia and AMD can sell their chips from AI to China. The amazing thing is that to achieve this they will give the US a slice of 15%

by

Nvidia and AMD have agreed to yield to the United States a part of the income from the sale of certain AI chips in China. This pact unlocks the export of these components to the Asian country after months of uncertainty, but does so with that unusual consideration. The context. The US government It has been for years imposing all kinds of prohibitions to Chips exports and advanced technology from AI to China. The goal has always been avoid that the Asian giant could compete. The shot has come absolutely for the cylinder headand the advance of Chinese AI models –As Deepseek– And chips –Like Huawei– They show that this tactic has not worked. Nvidia and its H20 chips. To try to avoid those vetoes, Nvidia He developed his H20 chip with the intention of meeting the requirements of the US government – not selling its most advanced chips – and thus continuing to obtain income in China. They didn’t even solve the problem, and the US government prohibited the sale of that chip in the Asian country. A dilemma that also involved AMD. US has faced for months A apparently impossible dilemma: to sell Hardware from AI to China, or that of not selling it to him and that they develop them. AMD was also in identical situationabsolutely blocked to be able to sell their chips from AI to China, which meant a colossal problem for their global income, which are nourished with force of sales in China. Solution: Give me my slice. What has unlocked all this scenario has been, of course, money. In an unprecedented agreement revealed In Financial Timesthe US government will allow NVIDIA and AMD MI308 to export to China, but 15% of the revenues of these sales will go to the United States government coffers. Jensen Huang had already notified. The CEO of Nvidia, Jensen Huan, already warned that the blocking of the sale of its chips in China could cause A reduction of 15,000 million dollars In your income this year. The Asian giant represents 13% of the total income of Nvidia, but The sanctions They threatened the survival of this company (and AMD) in that country. A successful meeting. According to FT, the US Department of Commerce began to issue export licenses for the H20 Chips on Friday, two days after the NVIDIA CEO met with the US President Donald Trump. That meeting seems to have been the definitive After the theoretical initial agreement that both had reached less than a month ago. This had never happened. This “Quid Pro quo” is not preceded, FT analysts stand out, who point out that no US company had previously agreed to pay part of their income to obtain export licenses for their products. Even so, the pact follows the dictatorial position of President Trump, which In addition to its badly called reciprocal tariffs Does not to demand that companies manufacture the chips used in products that are sold there in the US, such as iPhone. The forecasts. According to analysts of the consultant Bersntein, Nvidia would have sold about 1.5 million H20 chips in China without exports controls. That would have meant revenues of about 23,000 million dollars, but now that figure is probably lower. Even so, it is expected that Chinese companies make great orders of both the Nvidia and AMD chips. A worrying precedent. Meanwhile, certain experts criticize this type of agreement. Liza Tobin, of the Jamestown Foundation, commented on how “Beijing must be gloating to see how Washington converts export licenses into sources of income. What will be the next one? Let Lockheed Martin sell F-35 to China in exchange for a 15 %commission?”. Image | Nvidia | Dominic Kurniawan In Xataka | China’s first avant -garde lithography machine is not the biggest US problem.

The amazing history of John McAfee, photos converted into videos with AI and much more in 1×11 crossover

by

On one occasion John Mcafee forecast that Bitcoin would reach $ 500,000 of value in less than three years. And if I didn’t succeed, he said, “I will eat my penis on national television.” That challenging bet never occurred – Bitcoin has not gone from 110,000 in all this time – but also Mcafee would then reveal that it was actually a call of attention. It is one of the many anecdotes of the life of an entrepreneur who later took an absolutely unusual direction. He began his career as a brilliant programmer and had the vision of creating one of the first commercial antivirus, but after some years of business success, his life took a radical turn. An absolutely unusual one in which the sex, drugs and weapons They were an integral part. All in McAfee’s life was histrionic and exaggerated until it ended up being arrested in Spain for tax evasion. We talk about that unique life in this new 1×11 crossover delivery, but we don’t stay there. Jaume Lahoz and Carlos Santa Engracia are again the drivers of an episode in which we also have other surprises. For example, a review of the news with some of the hottest themes – will the future Apple Watch include a lies detector? – and in which we also introduce a new section. It’s about what has made us experience with Videos generated with AI But that do not start from a text prompt, but from a photo that “comes alive” as always surprising. We leave you with the episode, we hope you like it! On YouTube | Crossover
