Hubble made us believe that this exoplanet was impossible. James Webb just explained why we were wrong

by

In 2014, the exoplanet WASP-94A b was discovered, a hot Jupiter with an anomalous amount of oxygen and carbon in its atmosphere. The first observations pointed to hundreds of times more of these two gases than in the atmosphere of the Solar System’s Jupiter. This did not fit with standard models of planetary formation. It could be that there is some error in the models. However, according to what has just been verified with the James Webb Space Telescope, the problem was rather that the right telescope was not being used. Closer observation has shown that oxygen and carbon levels are actually much lower, consistent with known physics. Also, as a tip, something very curious has been discovered: that the planet has rocky clouds during the day that disappear when sunset arrives. A very useful transit. The authors of a study recently published in Science They took advantage of a transit of the planet in front of its star to study its atmosphere with the James Webb telescope. Previously, observations were made with the Hubble telescope. With it, the light spectra coming from the atmosphere could be analyzed and, with them, their composition could be established. However, since it was not a telescope capable of distinguish clouds from the rest of the atmospherethe calculations were an average of the gases of everything together. Said by one of the authors of the studywith Hubble the result was something like looking through a foggy window. Now, after giving the window glass a good look, they have been able to see exactly the composition of both the atmosphere and the clouds. Tidal lock. This exoplanet is tidally locked. This means which takes the same time to orbit its star as it does around itself. The result is that it always has the same face facing the star, so on half the planet it is always day and on the other half it is always night. It’s something like what happens to us on Earth with the Moon, which always has a hidden side for us. Despite having perpetual days and nights on each face, on this type of planets you can distinguish between sunrise and sunset, depending on the flow of gases in the atmosphere. The limit at which cold gases from the night side pass to the day side is considered the dawn of the planet, while the limb in which the opposite occurs is sunset. Different compositions. When observing the planet in full transit, the day side could not be seen, since it was looking towards the star. On the other hand, the James Webb has been able to capture the emissions from the two limits with the night side, considered sunrise and sunset. In this way, he has been able to verify two important pieces of information. On the one hand, what we mentioned: the levels of carbon and oxygen in the atmosphere are only five times higher than those of Jupiter. It is something that corresponds to other hot Jupiters and does not defy known physics. On the other hand, it has been seen that on the sunrise side there are clouds composed of silicates. That is, rocky clouds. However, these dissipate until they disappear on the evening side. Thanks to this duality, it has been possible to explore the pure atmosphere, with hardly any clouds, in the area of ​​the planet close to sunset. Unknown causes. The authors of the study do not know what causes this strange behavior of the clouds. However, they have two hypotheses. The first would be something similar to the process that gives rise to fog on Earth. The clouds would form in the darkness on the night side, then enter the intense heat of more than 1,000 degrees on the day side. The substances that make up the clouds would boil and the clouds would vaporize throughout the day, disappearing completely at night. Then, on the night side, the process begins again. The other hypothesis, on the other hand, suggests that there may be intense winds on the planet that are dragging the clouds into the interior of the planet and taking them out of sight by sunset. And now what? These scientists are already studying other hot Jupiters. At the moment, they have already detected two others with the same distinctive cloud cycle: WASP-39 by WASP-17 b. There is nothing like a good sample to properly study any scientific phenomenon. The more planets that are detected with the same circumstances, the better the reasons can be clarified.

Money doesn’t buy happiness. But it does give a monstrous Bugatti television that folds itself

by

A 137-inch television that, when you are not watching it, folds by itself and remains as a luxury decorative structure in your home. Yes, it is as crazy and absurd as it is real. Bugatti has presented to the world “his” first televisionone of the most spectacular on the planet. Of course, it needed a little help, so it relied on the work of C Seed, an Austrian display brand focused entirely on luxury. WTF. The chances of seeing the video of this television and not surprisingly, in my opinion, they are very low. In fact, the first thing I thought when I saw the video was that it was generated by AI. Mistake. The concept is “simple”: a television in 110 and 137 inch formats that folds in 45 seconds and remains as a very expensive decorative element in the home. Beyond the eccentricity, on a technological level it is truly amazing. Original design of the C SEED N1. Two of them can be configured in dozens of options. Bugatti version. Who is behind. The truth is that Bugatti did not invent this television, it was presented by the Austrian company C SEED in 2022 under the name N1, and it began to be sold to order in 2024. C SEED is a young company, founded in 2009 and with headquarters and production plant in Vienna. From the beginning, it focused on luxury televisions and solutions, both for mansions and superyachts, events, etc. It’s a small, absolutely niche company, so if you’ve never heard of it… you’re not alone. The bug. The Bugatti N1 is a complete redesign of the original N1, with materials and lines used in the Bugatti Tourbillona four-wheeled hypercar million of euros. And as for specs… 4K UHD resolution, HDR10+. Foldable microLED technology (five panels). Wisdom Audio self-deploying speaker system. Swivel system up to 180 degrees to the right and left. 1,000 nits brightness. 3m wide, 1.7 meters high, less than 10cm thick in its 137-inch version. 680 kilos for the 137-inch version. The five panels of the television unfolding. How is it possible. C SEED has not created a 137-inch folding panel, the TV is made up of a total of five microLED panels. This is one of the keys: it is not a typical panel with sub-panel hinges visible at a visible level, they are rigid and independent panels. The company has patented its own “Adaptive Joint Calibration” system, in other words, its electronic calibration system to align panel joints with millimeter precision in real time, making them indistinguishable to the eye. MicroLED technology is self-emissive, in which each LED is an individual, independent light emitter. This means that the system can precisely control the intensity, color and on-time of each pixel individually, including the pixels that are on the edge of each panel, next to the board. Go deeper. C Seed does not go into details about the manufacturing of the mechanism that rotates and hides the panel, although the documentation of the panel reveals some images of its interior. In them, we can perfectly appreciate the cavities that house the microLED modules, the screws and some of the joints of the system. In addition to this system, the audio system, signed Wisdom Audio, is especially striking. The speakers are hidden within one of the panel structures, and appear only when we need to play audio. The rest of the time they are hidden, to keep the design as clean as possible. I want one. The C SEED website only allows you to configure the television. Once we have done so, we submit the request and the company will contact us. Depending on the materials chosen, the customizations we want to make and the size, the price of the previous version was around $200,000, so add another few thousand for this Bugatti version.

The biggest culprit of children’s addiction to screens is not the TikTok algorithm: it is the parents themselves

by

Having children seems to activate a part of the brain that forces us to say the repeated phrase “Leave the machine now,” referring to the cell phone or portable game console. Here, logically, concern about the screen time of the little ones monopolizes the conversations of the most current parents, but the reality is that science is beginning to see that the fault for these behaviors really lies with the parents themselves. A reality. The debate over whether children are born “addicted” to technology fades when we look at the empirical evidence. It’s not just that the devices are designed to capture attention; is that a child’s first and most powerful learning algorithm is to observe their parents who spend the day in front of the screen. Bandura’s theory. To understand why the little ones don’t put down the tablet, you first have to travel back a few decades, to psychologist Albert Bandura’s social learning theory. This theoretical framework, widely validated, establishes that children do not learn primarily by what they are told, but by observation and imitation, especially of those they perceive as close and competent, such as their parents. Literally, we are talking about sponges that do not lose detail of anything. Four phases. In order to learn through this route, it is first necessary for the child to pay attention to the behavior of his or her ‘reference’ adult, such as his or her father or mother. From there, he will begin to retain the pattern made by his caregiver in his memory, almost as a normative behavior, and develop the physical ability to imitate the gesture. But it goes further, since by observing reinforcements, such as their parents laughing when they see the cell phone, an association with a positive stimulus is created. This is really important because you see that doing that action is something that is not dangerous at all, but rather fun and enjoyable. Modern pediatrics. Beyond this theory, a recent meta-analysis Published this year in the prestigious journal JAMA Pediatrics, it has analyzed the impact of the use of technology by parents in the presence of their children. This brings together a total of 21 previous investigations and covers 14,900 participants from 10 countries, empirically demonstrating that there is a direct association between the time that parents spend in front of a screen and the time that their children end up spending with them. But in addition, it has also been seen how it can generate a negative impact on children’s cognition or an increase in externalizing behaviors such as tantrums or anxiety. The cell phone on the table. The disconnection created by the smartphone not only creates a role model, but breaks the two-way interaction that children need for healthy brain development. Something relevant is that 70% of parents admit to being distracted by their mobile phone when they are with their children, and here is a study in Pediatrics in 2014 where this phenomenon was observed; This phenomenon has already been observed in the fast food restaurant environment. According to your data40% of parents were so engrossed in their devices during meals that they ignored their children completely. But even worse was when children tried to get their attention, often escalating their behavior, and simply causing parents to respond more physically or verbally when they felt interrupted. The recommendations. The American Pediatric Association is quite clear pointing out that children under 18 months should completely avoid screens, and in the 2 to 5 year age group it can be introduced for a maximum of 1 hour a day and as long as high-quality and accompanied content is watched.

NASA puts astronauts from the International Space Station on evacuation alert

by

It could have been just another day of work aboard the International Space Station, but the situation has taken a delicate turn. NASA has put in evacuation alert to several astronauts after an air leak in the Russian part of the orbital laboratory worsened, prompting the agency to order them to take precautionary shelter in a docked spacecraft. The order came from NASA mission control at 9:04 a.m., East Coast time of the United States (3:04 p.m. Spanish peninsular time). Several crew members were instructed to enter the ship SpaceX Crew Dragon and put on their corresponding space suits in case the situation led to an emergency evacuation. There are currently seven crew members on the ISS, but the preventive measure does not affect all of them. Bethany Stevens, of the NASA communications team, explains that The order reaches Americans Jessica Meir, Jack Hathaway and Chris Williams, from NASA; to the French Sophie Adenot, from the European Space Agency, and to the Russian Andrey Fedyaev, from Roscosmos. The leak is located in a very specific area of ​​the Russian segment: the Zvezda service module transfer tunnel, known as PrK. According to Stevens, that part of the station has been showing cracks and leaks for some time, an issue that NASA has closely monitored and that Roscosmos has tried to contain until now with operational measures and partial repairs.

Spain fails to comply with the rules with the registration of travelers. Brussels has just opened a file and gives him two months to fix it

by

The European Commission opened this Thursday an infringement procedure against Spain for the controversial traveler registry promoted by the Ministry of the Interior. Brussels considers that the rule violates European regulations on data protection in the criminal field, by forcing hotels, digital platforms and car rental companies to collect and send personal information of tourists to a state database that is then accessible to the Police. We tell you all the details. What are we talking about? This is known as the Traveler Registry, regulated by the Royal Decree 933/2021 and fully operational since the end of last year. The regulations obliges accommodations, travel agencies and vehicle rental companies to upload their clients’ data into the ‘ses.hospedajes’ application and transmit them to a centralized Government database. Just like point La Vanguardia, the objective declared by the Interior, which can be read in the preamble of the decree itselfis to reinforce the fight against terrorism and organized crime, activities in which, the ministry argues, accommodation and the use of vehicles have special logistical relevance. What a reproach Brussels. The Commission points to three specific problems. First, consider that the categories of data collected and stored are “excessive”, due to the variety of sets they cover, including payment and GPS data. Second, it maintains that access by police authorities “is not limited to specific and explicit purposes”, as required by directive 2016/680. And third, it describes as “disproportionate” that these data are kept for three years after the traveler’s stay. Amount of data. One of the big discussions revolves around how much data there really is to deliver. The hotel sector has denounced that the standard requires up to 42 different fields, while the Government insists that only 13 are mandatory: name and surname, number and type of document, reference and date of the contract, arrival and departure dates, means of payment, telephone or email and the relationship of kinship when a minor travels. The remaining data, according to the Executive, are not mandatory to complete. The file. The procedure opens a period of two months for Spain to respond and correct the irregularities. If the answer is not convincing, the Commission can issue a reasoned opinion, a kind of official ultimatum. And if non-compliance persists, the last step would be to take the State before the Court of Justice of the EU. The reaction of the sector. Hoteliers and travel agencies have been on the warpath for some time. The Spanish Confederation of Hotels and Tourist Accommodations (CEHAT) has questioned the legality of the collection and transmission of data because it conflicts with European regulations on free circulation and data protection. After learning about the file, the agency associations Fetave and Unav They have asked the Government the “urgent suspension” of Royal Decree 933/2021 and an immediate meeting with the Interior, considering that the Executive “cannot act as if nothing had happened” when Brussels has formally questioned the compatibility of the rule with EU Law. And now what. Spain has two months to make a move. Interior can defend the rule, modify it or suspend it while the procedure is resolved. However, pressure is growing, on the one hand from the tourism sector, which has been demanding changes even before the rule came into force; on the other, that of the European Commission, which had already warned of the clash of that decision with data protection regulations. Now that warning is in writing, so we will have to wait and see how things progress.

we must lift the accelerator of AI

by

Anthropic and OpenAI are competing in two parallel careers. On the one hand, the race to have the best model that continues to push cutting-edge AI. On the other hand, going public to become a public company. The winner of the first is debatable, but in the second competition it is Anthropic that has the advantage. This Monday he confirmed that had registered his application for the expected IPO, which could become the largest operation of this type in history which, as my colleague Javier Pastor commented, remember Netscape going public and marking the beginning of the dotcom fever. And, precisely in this scenario, the company has launched an interesting notice: a global pause must be made in the development of frontier AI. And it makes all the sense in the world at the same time that it is something that cannot happen taking into account the situation between the two powers that are in the current technological war. Taking your foot off the accelerator vs the technology race Anthropic has been using something curious for some time: the fear tactic. It is something that their main rival has thrown in their face (to automatically do exactly the same thing), but the truth is that Dario Amodei’s men from time to time drop some ‘bombshell’ about how We humans run the risk of losing control about this technology, with Amodei ensuring that there are possibilities that “things will go very, very bad.” In one publication Recently, the company behind Claude noted that they would be happy to take their foot off the gas on cutting-edge AI development only, and this is important, if they were confident that others would do the same. Again, they compare it with the development of war, as if it were an explosion in the number of nuclear weaponsnoting that they believe it would be a positive pause when comparing the rise of increasingly capable AIs with a “gun control problem.” When they talk about cutting-edge AI they refer to various models, but they focus on those that develop themselves. In a document shared this Thursday, two heavyweights from the company’s research team they affirmed that AI technology is approaching the point where systems can self-develop. That is to say: AI writing itself to improve. But, if they are so close (or so they say, since they have been talking about the same thing for months), why stop? Well, not for the technology sector, but for everything else. From Anthropic consider that a slowdown would allow other actors – countries and regulators, for example – to catch up with the technology. They comment that “it would be good for the world to have the option to temporarily slow down or pause the development of frontier AI to allow social structures and research to keep up.” The problem is coordination between countries because he does not trust at all that countries tell each other the truth. “AI training runs are much easier to hide than missile silos” As we read in The Telegraphthe company noted that “a significant slowdown or pause would require multiple labs with sufficient resources at or near the border AI agreeing to stop under the same conditions,” but the problem is that “it would also require each to be able to check what the others are doing and make sure they have actually stopped.” This has obviously brought criticism, such as that Anthropic is overestimating its capabilities (that’s why AI writes itself) or exaggerating the AI’s abilities so that it regulations are introduced that ‘harm’ their competitors. In any case, this stoppage is not going to occur in a context in which the United States and China cannot allow themselves to take their foot off the accelerator when they find themselves in a contest in which China is clear that wants to be the first technological power in the short term and the United States, evidently, does not want to allow it.

The new Ninja AutoBarista Pro coffee maker with which you will prepare the perfect coffee at home without being an expert is now on sale in Spain

by

Making specialty café-quality coffee at home typically requires two things: a significant investment in individual tools and some time learning to master grinding, pressing, and texturing milk. To break this barrier, Ninja has just announced the launch in Spain of the Ninja AutoBarista Pro (899.99 euros) an all-in-one automatic system that seeks to unify the versatility of barista drinks with the convenience of a single button press. Ninja AutoBarista Pro Automatic Coffee Maker The price could vary. We earn commission from these links A coffee maker with full automation: from grinding to foam type This device comes to the market with a clear proposal: eliminate complex manual steps through an intelligent system that automates the entire process, from the bean to the cup, without the user needing prior knowledge. The core of this coffee maker lies in its AutoBarista technology, a set of sensors and calibrated systems that make technical decisions for the user. Instead of having to manually adjust the grinder’s coarseness or control the extraction time, the function Grin iQ It analyzes the type of grain selected and adapts the grinding automatically to extract the maximum flavor. To these is added a pressure and temperature management that adjusts depending on whether we are going to prepare a espresso short or a long filter coffee. Versatility is another of its strong points. It incorporates two independent 340 gram bean tanks, allowing you to switch between different varieties of coffee cleanly and without mixing the beans. It also has a double brew function to make two doses of espresso simultaneously. He milk texturing This is usually the most difficult step to replicate at home. To solve this, the system FrothPerfect It allows you to work with both milk and vegetable drinks, offering five different consistency levels that range from hot milk without air to extra dense foams or, a highly requested function in summer, cold foam for recipes with ice. Finally, and thinking about individual preferences, the coffee maker allows configure up to two user profiles to memorize the exact intensity, water volume, temperature and preferred foam style. ⚡ IN BRIEF: Ninja AutoBarista Pro Automatic Coffee Maker ✅ THE BEST Extreme versatility (hot and cold): what really makes the difference is the ability to do Cold Brew and foam cold milk automatically.

Disney has invested more than 5.7 billion euros in Disneyland Paris. He still hasn’t recovered even half of that amount.

by

On March 29, 2026, Josh D’Amaro inaugurated World of Frozen before Emmanuel Macron, Penélope Cruz and Naomi Campbell. It was his first major public act as CEO of Disneyeleven days after taking office. However, he did not do it in the now classic Disneyland in Orlando, but in Paris. A park that, according to French commercial recordsaccumulates a deficit of 4.2 billion dollars after more than three decades open. Disneyland Paris is Disney’s most profitable international subsidiary and even so, it still You have not recovered your initial investment. So…why is it still open? On paper, all good. When Disney makes public the financial results of your parksit doesn’t break it down by installation. But since Euro Disney Associés (EDA), the company that manages the complex, is obliged to publish detailed accounts in France, we can know the Parisian figures: in the year ending in September 2025, EDA’s income reached a record of 4 billion dollars, 8.4% more than the previous year, driven in part by the implementation of the controversial dynamic prices. Net profit reached 304.2 million, also the highest in its history. For its part, the results of Disney’s international parks segment They rose 25% in the last quarter of fiscal year 2025and the company explicitly attributed that improvement to the pull of Disneyland Paris. Do the math. However, since opening in 1992, what was initially known as Euro Disney has only made a net profit in 13 years. Accumulated losses total 3.7 billion dollars. In other words: Disney has invested a total of 6.8 billion dollars (5.7 billion euros) in the complex and has not yet recovered that figure. With 304 million annual profits, it is difficult to think of it being recovered. The French trap. EDA operates within particular financial parameters. France gave up the coveted 2,230 hectare land in Chessy (almost a fifth of the area of ​​Paris) in exchange for the complex being organized as a public-private collaboration. Disney started as a minority shareholder with 49% and since it was not the main shareholder, Disney did not capitalize the company as it would have done in its American parks. It only contributed 132.1 million of the 4.9 billion that the construction cost. The remaining 59.8% was covered by a bank loan assumed by the Euro Disney joint venture. EDA was listed on the Euronext, which on the one hand forced accounting transparency, and on the other hand chained the company to a very fragile capital structure just before the first great recession of the time hit. A year after the opening, Philippe Bourguignon, president of Euro Disney, recognized that the company’s financial imbalance was so severe that its very existence was at risk. Crisis after crisis. In reality, the history of Disneyland Paris is a summary of the great economic crises that the sector and, specifically, France has experienced. The park opened during a recession that affected all of Europe, but especially the country (with a drop in GDP of 1.5% in 1993). French tourists rejected the prices of tickets, the absence of alcohol in restaurants and English as the dominant language. Disneyland Paris’ second park, Walt Disney Studios (renamed Disney Adventure World in 2026), opened in 2002 just as global tourism was suffering after 9/11. The worst year came in 2016: Disneyland Paris posted a record net loss of $961.8 million after the November 2015 attacks plunged attendance at the park. Disney’s reaction in 2017 was to buy the remaining 51% of shares for 250.8 million and pay another 1,700 to eliminate all the accumulated debt. But the misfortunes did not end: the 2020 pandemic cut off the recovery that this sanitation had started. And things are not over: the war in the Middle East affects energy and flights, and it remains to be seen how it will impact the business in the medium term. The clear accounts. For 34 years, the royalties and other management expenses that EDA has paid to the American parent company total 2.4 billion dollars: fees for attraction design, licensed characters, costumes, show production… But Disneyland Paris receives 16 million visitors a year, it is the most frequented tourist destination in Europe and, according to the study itself contributes 6.1% of France’s total tourist income. In 2025, the parks and experiences divisions generated the 57% of Disney’s consolidated operating profiton total revenues of $94.4 billion. It is the weight of that segment that took D’Amaro from parks management to CEO. But one thing is clear: EDA cannot distribute dividends until its accumulated losses are fully compensated. At 304 million in annual net profit and with the historic hole unclosed, that moment is not around the corner: it seems that we are not talking about short-term compensation.

“Women continue to look for answers outside the health system”

by

For decades, the menopause It has been a topic relegated to the private sphere and, too often, silenced in medical consultations. Given the lack of accessible clinical information, the Internet has become the great refuge for many women who need to resolve their concerns and do not know where to turn. However, what search engines return has changed drastically: health has given way to marketing. What has been seen. A new study published in JAMA has put figures on this phenomenon by analyzing search patterns in Google Trends over two decades in the United States, the United Kingdom and Australia. Based on all this information, researchers have detected an increase of between 15 and 20 percentage points in searches aimed at commercial products and services. That is why the internet is no longer just a place to search for the meaning of a symptom; It is an immense showcase of payment solutions. The health system. This commercial shift in search engines does not occur in a vacuum, but, as Nuria Marín, a menopause specialist, points out, in his analysis for the Science Media Center Spain, the massive increase in these searches reflects a worrying reality: there are fundamental needs not covered in the traditional health system. Women turn to the Internet because they do not find the time, specialized management or comprehensive answers to their routine consultations. However, the study of JAMAdespite being published in a high-impact journal, has a methodological limitation that Marín highlights: Google Trends is an algorithmic and “blind” tool. It does not tell us the age, biological sex, or exact menopausal status of the person typing, which prevents us from establishing direct cause-and-effect relationships at a clinical level. The misinformation. The real problem with seeking answers to questions about our own health is that the algorithm rewards economic profitability over scientific rigor. This means that when a patient searches for information about menopause, she enters a digital ecosystem full of interests. Here is a 2025 study published in B.M.J. revealed that 77.2% of online content on hormone replacement therapy to ‘treat’ menopausal symptoms presented commercial conflicts of interest. But even worse is that 67.2% of the medical claims on these pages They openly contradicted official clinical guidelines based on medical evidence. The quality of the information is quite doubtful, since it was seen that 35% of the websites on menopause had some type of medical quality certification, and more than half required a level of reading comprehension much higher than that recommended for health dissemination. Side B. Not all of the technological landscape is negative, but we have tools that, when designed based on scientific evidence and not aggressive marketing, prove to be a great support for women. Here we have, for example, mobile apps to monitor symptoms which point out that women can see their physical symptoms reduced due to the very fact that the patient structures what is happening to her. That is why the challenge we have ahead of us right now is to offer access to this type of tools and to destigmatize menopause in society.

Anthropic’s AI already writes 80% of its own code because it was inevitable that AIs would improve themselves

by

“As of May 2026, more than 80% of the code we integrate into the Anthropic codebase was created by Claude.” Those who reveal this information are two Anthropic researchers who have published one of the most revealing texts about the present and future of the company’s AI models. One that tells us about a fascinating and disturbing concept in equal parts called recursive self-improvement. Code multiplier. The impact of these agentic programming tools on the work of Anthropic engineers is being spectacular. According to internal Anthropic data from May 2026, this autonomous code generation has caused an Anthropic engineer to produce eight times more lines of code per quarter today than during the 2021-2025 period. Anthropic’s human programmers they no longer program– Direct and review AI-generated code. A frenetic evolution. The changes we have experienced have been fascinating, they explain in Anthropic. Between 2021 and 2023, engineers wrote all code by hand on their computers. In 2024 they started using chatbots to generate small snippets of code that they then copied and pasted. In 2025, agents capable of work autonomously on entire files. Longer time in a row. According to the METR benchmark which measures the ability of AI to complete complex tasks, in 2022 GPT-3.5 could barely last about 35 seconds operating autonomously without making serious errors. By mid-2026 Claude Opus 4.6 is already capable of working 16 hours in a row on complex tasks. At Anthropic they point out that the length of tasks that an AI model could undertake doubled every seven months, but now it doubles every four. If this trend continues, “tasks that take a person days could be automated with AI. By 2027, AI systems could be able to work on tasks that take a person weeks.” Superhuman performance. Industry benchmarks are being “saturated” by new AI models, which already reach almost 100% of the possible score in many of them. For example SWE-bench, which measured the models’ ability to program, was almost is surpassed for the most recent models. In 2025 Claude pus managed to optimize the code they gave him by making it ran 3x faster. In April 2026 Claude Mythos Preview already achieved a 52x speedup of that code. AI that improved itself. This concept of recursive self-improvement presents a scenario in which an AI model generates data, corrects its own failures, and trains itself continuously. This opens the door to exponential growth in its capabilities, but at the same time reopens a debate on the risks that this type of evolution generates. Source: Anthropic infinite loop. Traditionally, human engineers analyzed the responses of a model, cleaned the data, and adjusted parameters to create the next version of that model. With recursive self-improvement AI takes on that role and evaluates its own performance, generating more complex problems to test itself and generating synthetic data for your next generation. Danger. This autonomy implies a potential risk: that humans lose control of where the AI ​​goes. That we do not know or can assure if it is aligned with our ethics and ideals. The biaseshowever small, can be amplified with this type of iterative process, but the model itself may have mutated its original ethical reasoning mechanisms and security protocols to become something totally unpredictable. The Terminator scenario. Isolation and arbitration. To avoid these risks, at Anthropic they implement this evolution in isolated environments to then verify that everything works as it should. In addition, the company uses independent evaluation models that act as independent arbiters that audit these models. that evolve by themselves. They do this by checking each change in the code to prevent its impact from being harmful to the system or to those who use it. The new bottleneck is the human being. The Amdahl’s law is a formula that is used to find the maximum performance improvement of an information system when only a part of that system is improved. At Anthropic they point out how as AI continues to write more and more code, the real bottleneck is the human being who has to review that code. In Xataka | Anthropic is one step away from being worth as much as Samsung. And what the market is buying is not Claude
