Henry David Thoreau, philosopher, “in my house I had three chairs, one for solitude, another for friendship, and the third for society.”

A philosopher alone in a cabin in the middle of the forest. Everything else is silence. For decades and decades, Henry David Thoreau has been the canonical example of simple living and meditation. Phrases like the one that heads this article about the chairs that the American thinker had in his country house. But history has not been exactly like that: Thoreau’s cabin was less than three hundred meters from the train track; He, in fact, went down to the town almost every day and, once, he put almost thirty people in there. The explanation is simple, of course. Thoreau’s quote (his entire work, in fact) is not about loneliness, nor about self-sufficiency, nor about self-control. The phrase is actually about balance. What exactly does Thoreau say? The text is in Walden (1854)in the chapter dedicated to visitors. It is also slightly different from the one that usually circulates: he says that he had “one chair for when he is alone, two for when a friend visits him and three for society.” And it seems like a matter of nuance, it’s true. But it is not. When Thoreau wrote this he was already fed up with being called a ‘hermit’. He says it himself in the book (“I think and love society as much as anyone else”), but above all he shows it. Henry received more visitors during his forest retreat than at any other time in his life. His experiment in recollection (the two years, two months and two days that it lasted) was a period of self-knowledge, but nothing more. It was Thoreau playing to find out who he wanted to be when he grew up. And why is all this important? Often, we think that others can help us because they have gone through the same things as us; because they have climbed the same mountain as us. But it’s not true: no one is actually climbing that same mountain. Others are helpful because, as they climb their own mountains, they have a unique perspective on what lies ahead and what we have left behind. We live in an epidemic of loneliness. In November 2023, the WHO declared unwanted loneliness a global health threat and set up a commission on the matter, which published its report in 2025. That’s where Thoreau can help us. Because the lesson of the three chairs is not what they sell us. It’s not “sit in the first chair.” The lesson is to have the three chairs ready: seeking moments of chosen solitude feels good, but imposed and chronic loneliness makes us sick. So yes, it is worth remembering good old Henry David Thoreau: let’s count the chairs carefully.

a historic family from Valencian high society bets on photonic semiconductors

The Valencian saga that has made part of its fortune bottling soft drinks is now taking a technological leap: a chip factory that uses light instead of electronswith almost 25 million of public money. The general overview. The Council of Ministers has approved almost 25 million in public financing for Attypics Photonicsas reported exclusively He Confidential. The company, 100% controlled by Baladre Capital (the holding company of Álvaro Gómez-Trénor, director of Coca-Cola Europacific Partners), plans a total investment of 50 million to build a photonic chip plant in Paterna, a municipality a few kilometers from the Valencian capital. The State enters with 49% through the Perte Chipthe semiconductor program linked to Next Generation funds. The context. The Gómez-Trénor They are an old acquaintance of Valencian high societywith two centuries of history that starts with an Irishman named Thomas Trenor Keating: He founded the Trenor Bank, traded in guano and got involved in the region’s agri-food industry. Nine generations later, the saga accumulates noble titles, historical properties (from the monastery of Sant Jeroni de Cotalba to buildings in the center of Valencia, passing through a park for public use in Torrent) and a reference position in the province’s business community. In detail. Attypics was born in April 2026 from a team of researchers from the Polytechnic University of Valencia with more than fifteen years manufacturing photonic chips. The integrated photonics processes and transmits information using light instead of electrons: more speed, less energy consumption. The company wants to be the European private benchmark in the model Lab-to-Fab (from the laboratory to the factory) covering from prototyping to the manufacture of 200 and 300 millimeter wafers. The first phase includes 1,240 square meters of clean rooms and 100 direct jobs. The second would expand the facilities to more than 7,500 square meters and would exceed 300 jobs. Why is it important. Photonic chips are destined to be infrastructure in AI data centers, quantum telecommunications and high-performance computing. Europe has been trying for years to reduce its dependence on Asia and the United States for semiconductors, but private projects that actually materialize are rare. That a family with its own capital, stable dividends from Coca-Cola Europacific Partners and no need for advertising decides to commit 50 million to this niche says a lot about how certain family assets are reading the next decade. Entering now, with state support and a consolidated scientific team from the UPV, has overwhelming logic. Yes, but. Attypics is barely three months old. Integrated photonics is a field where the gap between the laboratory and industrial-scale production has brought down projects with more muscle than this. Depending on the Perte Chip also implies being exposed to the rhythms of the public administration, whose management of European technology funds has a bittersweet history in Spain. And the Gómez-Trénors, much more accustomed to collecting dividends than managing semiconductor factories, will have to demonstrate that the scientific capital of the UPV can become a sustainable business without the university umbrella.

“Society will not tolerate that only a few companies do all the learning”

That things are not very good lately in the tech industry is a reality (depending on which side you are on, of course). The economy around the exacerbated demand for AI data centers It has become so devirtualized that it is no longer surprising that a major technology company has spent tens of billions of dollars on another big deal. And as a consequence of this, component shortage It is making the purchase of technological products by the consumer increasingly more complicated. So yes, you could say that things are not very there. But there’s also some comedy in Microsoft CEO Satya Nadella coming out to point this very thing out. And the company precisely contributes greatly to the situation we are experiencing. In an interview For the Wall Street Journal, Nadella warns that the current AI development model is neither sustainable nor legitimate in the eyes of society. What is this about? Nadella has long warned that AI has to generate real impact to justify the resources it consumes. Already He did it last January at the World Economic Forum in Davos, where he warned that if AI tokens do not improve tangible results in health, education or productivity, “social permission” to continue allocating energy and money to their development would be lost. Recently, in a similar speechhas dared to point out those who, according to him, are concentrating too much power. Concentration. For Nadella, a small group of companies (those that build the most advanced models, such as OpenAI, Anthropic or Google) are accumulating the value generated by AI while, at the same time, stirring up fear. And the conversation in recent years has revolved around topics such as massive job lossesthe existential risks about its use and about how these companies require almost unlimited resources to continue growing. “You can’t say that all white-collar jobs are going to disappear, that this could be a weapon, and at the same time use all the power available to build data centers,” counted the executive to the WSJ. Society is not going to tolerate a few models and a few companies “doing all the learning in the world,” he continued. “Narrative is not enough because now we have to demonstrate with facts,” he insisted to the medium. Who he points to without naming. Nadella does not mention specific companies in the interview, but the context says it all. Dario Amodei, CEO of Anthropic (and Microsoft partner with a multi-million dollar deal signed last year) predicted in 2025 that AI could eliminate half of jobs entry-level before 2029. Sam Altman, CEO of OpenAI (another long-standing Microsoft partner, in which the company has invested billions) has also made similar warnings about employment, although recently he admitted he was wrong in their predictions. Both companies have led to tensions with the United States Government regarding the safety of its models. What Microsoft is doing. Nadella also points out in the interview that Microsoft has launched a series of low-cost models to make access to AI cheaper for its enterprise clients, and has presented Copilot Coworkan autonomous AI agent that allows the user to choose between different models (including the cheapest ones) depending on the task. The WSJ points out In his article, the company is also considering whether to host a version of DeepSeek on its platform, a company that not long ago turned the technology industry upside down with its R1 model (it is also a company accused by OpenAI and Anthropic of having copied their models). The vision it proposes. For Nadella, the future of AI lies in a more distributed model, that is, companies using their own data, with access to a variety of models at different prices, without depending on a handful of suppliers. He defines the companies of the future as “continuous learning systems” that combine human knowledge and AI. In Nadella’s vision, a company’s capital would not only be its assets, but also its ability to process and learn, something he calls “token capital.” And he warns that protecting intellectual property will be key so that companies do not become mere executors of what the big models dictate. Between the lines. Nadella’s position also has a strategic reading. And Microsoft has not managed to develop its own model that competes with the most advanced ones from OpenAI, Anthropic or Google. Furthermore, according to share WSJ, its Copilot users have begun to prefer alternatives, according to data from the analysis firm Recon Analytics. Without its own header model, it is in its best interest for the market to move towards variety and price competition, and not towards consolidation around the most powerful models (which are, precisely, those of its partners).

how to prevent society from collapsing because of AI

Everyone seems to be clear that AI is going to have an impact on the labor market, the problem is that They do not agree on what that impact will be like.. While some say that will destroy many jobsothers predict that will create many more. In the midst of this discussion, a group of experts met to try to imagine what the world will be like in 2030. Spoiler: it doesn’t look good. The meeting. They tell it in the Wall Street Journal. Last week, 40 experts in areas such as technology, economics and public policy met in a building in Washington. At the meeting they analyzed scenarios on how AI will transform American society by 2030. Their objective was to propose strategies to minimize the negative impact on a social level, because they assume there will be one. The meeting was organized by Windfall Trustan independent organization that seeks to anticipate and manage the changes that AI will bring, designing policies and legal frameworks so that wealth is distributed fairly. Macro prosperity. The scenario that was proposed at the meeting was called ‘Prosperity on paper’. In it, these experts draw a flourishing economy in macro indicators, but that hides an important social problem. In this scenario, AI has almost doubled the US GDP, labor productivity is skyrocketing, and the S&P500 index is rising. Micro precariousness. On paper everything is perfect, but the reality is that society is going through a serious employment problem, not because of the rise in unemployment (which is also true) but because of what they call “underemployment”, which is expected to rise from 8 to 14%. Many people have casual, part-time jobs or are forced to accept jobs for which they are overqualified. Blue collar jobs. It seems clear that the impact of AI on employment will mainly affect white-collar workers, that is, office workers. Many see an opportunity in blue collar jobs such as plumbing, electricity or masonry. However, according to these experts, although there will be an increase in demand and salaries for these professions, it will be temporary. All those office workers will flock to learn traditional trades, which will cause an increase in supply and a drop in value. cso everything bad. Experts predict that this contrast between what the data says and the reality of the working class will cause political unrest to skyrocket, the generation gap to widen, and also a decrease in the birth rate due to the discontent of young people. But not everything will be bad, they also foresee that healthcare and education will be cheaper thanks to AI tools and that people will have more free time to do creative activities. So what. The objective of the meeting was to propose possible policies to prevent this scenario from occurring and attendees had several ideas. The proposals focus on two major fronts: on the one hand, an effort to requalify and train workers, and on the other, create mechanisms that allow the wealth generated by AI to be redistributed, such as the universal basic income that Elon Musk himself mentionedspecific taxes on AI companies and even creating a sovereign fund where part of the profits go. The attendees themselves admitted that political polarization will make it very difficult to approve reforms of this caliber, although they are clear that leaving things as they are will probably be much more expensive.

One of the biggest mistakes we are making as a society is assuming that living tired is normal.

Spain is one of the European countries where the most workers They link their psychological discomfort to work and, in fact, sick leave due to mental disorders have more than doubled since 2016. That’s the bad news, the good news is that we’re starting to know why. Although that, if we are honest, if we think about it, it is not such good news either. we have become accustomed We have normalized being exhausted… According to the OSH Pulse 2025 survey of the European Agency for Safety and Health at Work40% of Spanish workers link their stress, anxiety or depression directly to work. The European average, to contextualize the problem, is 29%. Only four countries (Greece, Finland, Cyprus and Poland) surpass us. …and we know exactly why it happens. In 1993, Bruce McEwen and Elios Stellar developed the idea of ​​’allostatic load’. That is, the physical and psychological ‘wear and tear’ that the body pays for adapting again and again to chronic or repeated stress. It is not a small price: the cardiovascular, metabolic, immune and neuroendocrine wear and tear is enormous and has consequences. A 2021 systematic review makes clear that a high allostatic load is related to increased all-cause mortality, cognitive impairment, chronic fatigue syndrome, diabetes, cardiovascular disease, and psychiatric disorders. It is logical: when stress mediators (cortisol, adrenaline, etc…) remain chronically activated, the brain gets used to it, the body begins to work above its capacity and the systems suffer. Furthermore (and this is very curious) it seems that chronic stress deteriorates the same brain areas that allow us to realize that we are wrong. The (not so great) Spanish paradox: Our country not only has some of the worst work stress data in Europe, but the preventive resources They are among the lowest on the continent. That is, we have a problem, but we are not spending too much money to solve it. And it’s just a question of money. According to the same survey, 54% of Spanish employees fear that revealing a mental health problem will harm their career. And how do we solve it? Normally, experts understand that there is an individual approach, a union approach and a health approach. In Spain (and here the media is very much to blame) we tend to focus on the individual who, furthermore, is the one who less evidence of systemic efficacy has behind. So maybe the only thing we can do is start taking it seriously. Image | Luis Villamil In Xataka | Only one in four Spaniards has rested on vacation. The culprits: work anxiety and the inability to disconnect

What are solar storms and why society has become so vulnerable to something that has happened millions of years

“Understanding the space climate is not an option.” With this lapidary phrase summarizes its efforts to predict solar storms the European Space Agency. They occur since the sun exists, and some of the most powerful They are recorded in the trees rings. But they are not our ancestors, but we, the most dependent civilization of the technology that the earth has ever stepped on, the most vulnerable to them. But what exactly are solar storms? How are these energy outbreaks? And the million dollar question: can we predict when the next one will impact on earth? The answer is in a complex network of satellites, artificial intelligence models and constant surveillance of our star by space agencies. What is a solar storm 150 million kilometers away, the sun flushes with a magnetic activity so powerful that, from time to time, it goes out of hand. A solar storm is a sudden explosion of energy, plasma particles and magnetic fields that the sun releases towards the solar system. If the ejection occurs in the direction of the Earth, the solar storms can produce more intense auroraslike those that were seen in much of the world in May 2024. But they are not only a show: in our technological civilization, they are also a threat. To understand them, we have to differentiate their two main components. The guts or solar flares. They are a intense radiation outbreak: A whip of energy released when the magnetic fields of the sun tense and break. This radiation travels at the speed of light, reaching the earth in just eight minutes. They are classified according to their intensity by X -ray flow, measured in watts per square meter. The class A, B and C are the weakest, and those of class M and X, the most powerful, which usually cause interference in short wave radio communications. Coronal mass ejections. It is the ballistic part of the solar storms. While fulguration is the flash, the coronal mass ejections They are the “cannon bullet”: a gigantic bubble of loaded particles (plasma) and magnetic fields that are thrown into the space at speeds of millions of kilometers per hour. This massive cloud of solar material It takes between 18 hours and a couple of days in crossing the space to cross with our planet. Not all guts are accompanied by a coronal mass ejection, but when they occur together and in the direction of the earth, they are a powerful cocktail that can put astronauts at risk, knock down satellites (as happened during a Starlink deploymentor fry electrical installations on land (As in the Carrington event). How they form A Class M. Image: That The origin of the solar storms is the magnetic field of the Sun. A star is not a solid ball, but a sphere of rotation plasma. But it does not rotate uniformly: his Ecuador turns faster than his poles. This differential causes the magnetic field lines to twist, tangle and accumulate an enormous amount of energy, as if they were elastic gums twisted to the limit. These areas of intense and complex magnetic activity They usually manifest as sun spots on the visible surface of the sun. When the accumulated tension becomes unsustainable, there is a magnetic reconnection event: the lines are broken and violently reorganized, suddenly releasing all the stored energy. This release drives the guts and can launch into the mass of the solar crown. The intensity of its effects on Earth depends on its speed, its size and, above all, the orientation of its magnetic field. If the magnetic field of coronal mass ejection is oriented towards the south, it is aligned in opposition to that of the Earth, our protective shield, which allows a much more efficient and destructive energy transfer. How they affect the earth If we are here it is because the magnetic field and the atmosphere of the earth protect us from radiation. Solar storms are not a direct risk to the health of living beings on the earth’s surface. For astronauts it is another song. In 1972, shortly before the Apollo 17 mission, there was an intense solar storm that would have inoculated a mortal amount of radiation in astronauts if they had been on the surface of the moon. Today, astronauts who work in the low land orbit, even protected by the magnetic field, plan space walks according to the space climate. The really vulnerable to intense solar storms is our technological infrastructure. When a coronal mass ejection impacts the earth’s magnetosphere There is a geomagnetic storm. Extreme cases can induce electric currents in high voltage lines, overloading transformers and raising the risk of blackouts, especially now in summer, when the electricity grid is already very tension. The satellites, despite having mechanisms to avoid induced currents, usually carry the worst part. Solar storms expand the upper atmosphere of the Earth, increasing friction and accelerating the fall of satellites that orbit the earth at low height. This effect already is accelerating the fall of Starlink satellitesthe most large constellation of the low orbit. Even during moderate geomagnetic storms we can notice some effects, such as precision errors in GPS systems or that airlines deflect flights from polar routes to avoid failures in plane systems and protect passengers. The kind face of solar storms are the auroras: solar particles that when hitting our atmosphere They create a light show at the poles. During severe geomagnetic storms, dawn can also be seen in less common latitudes. When the next solar storm will occur Image: that The most severe geomagnetic storms occur Around solarthe period of more activity of the Sun in its 11 -year cycle. Now we are going through solar cycle 25, and we approach the maximum activity, planned by the NOAA and ESA by the end of 2025 or early 2026. This means that we are in a high probability phase of intense storms. Luckily, spatial meteorology is advancing by giant steps. To predict solar storms, … Read more

China needs cardiologists in an increasingly aged society. His answer is an AI that “reason” as the best

820,000 people. That is the number of patients that the Department of Cardiology of the Zhongshan hospital attended in 2024. A very high figure for a country in which doctors are missing and that sees that, every so often, every so often, His hospitals overflow. Increased higher health coverage, especially for an increasingly aging populationand the answer has been found in artificial intelligence. In a cardiologist, specifically, which has trained with a base of hundreds of thousands of people and has all the support of the government. Cardiomind. That is the name of artificial intelligence that has been developed by the Zhongshan hospital, the University of Fudan and the Shanghai Artificial Intelligence Academy for Science. It is a joint effort to create an AI that, according to them, is able to reason as their best cardiologists. GE Junbo is one of those outstanding cardiologists of the Chinese Academy of Sciences and Comment They are feeding the system with data, but they also teach him “to think as an expert first level cardiologist.” Co-pilot. In this way, Cardiomind compares patient history and the results of tests based on global research to generate diagnostic suggestions. And if you were raising one, leaving the possibility of leaving your heart’s health on the awareness of a machine, in the word “suggestion” is the key. According to its creators, the idea is not that doctors are replaced, but that it helps those members of a congested system to work faster and more accurately. “With their help, our doctors can attend more patients, reduce the workload and improve both the quality of the diagnosis and the treatment,” commented The doctor. Pillars. The secret of the pizza is in the dough, in the case of AI, that special sauce is the training. Cardiomind is a multimodal system that can analyze and process data from various sources (electrocardiograms, ultrasound and laboratory results, for example) to provide its diagnosis, and it is what has been trained. The source has been hundreds of thousands of medical records that the Hospital Cardiology Department had stored for decades, learning in the process how doctors think both in the diagnosis and during treatment. In addition to multimodal and very trained, it specializes in one thing: cardiovascular diseases. Total government support. And all this comes from the hand of itself. China is investing strong in development of artificial intelligences and, although in the West only a few as Deepseek They are the ones that attract attention, the country has been betting for the development of these systems to decongest several organisms. And that of medicine is fundamental. In January of this year, and apart from Cardiomind, established In Shanghai the first test and verification center of large models of AI in the field of medicine. Their fields will be assistance, disease prediction, personalized treatment according to the history of each patient and support to develop drugs. Necessary. Such is that impulse that several hospitals already have their own AI platforms, even some that They combine Contemporary and traditional medicine. And the reason why this technological development is being promoted is the one mentioned above. The population is getting older and doctors are missing. It is estimated that the country has 1.9 doctors per 1,000 inhabitants and They want have 5.5 nurses per 1,000 people for this year. In other countries, the average is devastating. In Spain, for example, there is 6.21 doctors per 1,000 inhabitants. In the case of nurses, the figure is 7.12. Challenges. Now, despite that government impulse, there are three elements to take into account. One is that of the data security to guarantee privacy. In the case of Cardiomind, those responsible developed a firewall with encrypted data. Other countries are studying How to apply AI in cardiology and, precisely, data leakage and ethics is a point that is usually present Among the concerns. Ethics also plays a role, since if it goes from suggesting to a more important role, it would be necessary to legally regulate it. At the moment, or they are in charge “only” of paperwork and records or, if they attend decision making, the last word has a human. In addition, there is the technological issue itself. The development of these artificial intelligences needs servers and calculation power. It is something that China is solving more or less controversial forms buying items that They should not be able to buy due to the commercial war with the West, but also using solutions developed at home, such as the chips of a huawei that is the spearhead in development of hardware for AI in the Asian giant.
