China is making time its best resource. Its rapid iteration is unique

by

China has open fronts in practically any technological fieldand in recent years we have seen how the country has opted in a mastodontic way in areas that could decide its position in the next decade. The Asian giant knows that time is one of the most valuable resources in the digital era, and therefore its digital manufacturing ecosystem and ultra -grape iteration is changing the rules of the game worldwide. A silent revolution. What took months to develop now is completed in weeks. The medium baiguan I explained it Through a visit to the facilities of a Robotics Startup, where it indicated that modifying a structural component at an early development stage required opening molds, a process that could cost about 200,000 yuanes and several months of waiting. “The development cycle, which used to last between one and two months, could be shortened one week or a few weeks with the help of digital manufacturing and 3D printing,” assured The medium. The processes now allow multiple iterations in the time that took time to complete one. The perfect speed ecosystem. In this sector, China does not dominate just by having cheap 3D printers manufacturers. According to the medium, its real advantage lies in an integrated ecosystem that includes ultra -efficient logistics networks, interconnected software and hardware suppliers, and a delivery capacity that allows to close the market feedback cycle in record time. The medium Point out To the Miniso company as an example: from design to sale, the entire process is digitized and can be completed in a week. Figures. Between 2015 and 2022, China’s additive manufacturing sector grew by 30% per year, According to Am Research. The firm specialized in market analysis projects that the country will obtain revenues of about 8,000 million dollars only in 3D printer sales by 2032. To put it in context, China represents 50% of the global industrial robots installation, compared to 25% in 2015. Companies like EPLUS3D have already developed metal printers with up to 64 laserssurpassing Western competitors such as Nikon SLM Solutions, who stay in 12. Cheap labor costs, yes, but there are more. For years we have thought that Chinese competitiveness was based solely on economic labor or flexible regulations. However, Baiguan appointment Its extraordinary digital capabilities, flexible supply chains and ultra -grape mechanisms for market feedback. From Roborock to Pop Mart, Chinese companies are gaining global market share not only for being cheaper, but for iterating faster. The challenge for the West. China allows companies to deduce 200% of their R&D expenses for taxes. As Point out Forbes, the United States reduced that 100% to 10% deduction in 2017. In addition, it must be taken into account that Chinese companies not only dominate their domestic market. And as explained by the media, China is engaged by opening offices both in Europe and the United States, offering cheap significant equipment without sacrificing quality. China uses time in its favor through the development of new technologies, and it is the same time that will tell us where the country will be located in the next decade.

The irrational fear of changing jobs has a name and influences your decision making: sunk cost fallacy

by

Often people They cling to jobs that they no longer satisfy them – or that, directly, They do not support-, but they resist leaving it moved by the fear of losing everything they have invested to get to where they are: time, effort or training. Although it may seem strange, this behavior responds to a psychological bias called sunk cost fallacy. This bias can delay decision making to leave a job and perpetuate itself in an unfavorable work situation that can even affect mental health .. What is the sunk cost fallacy? Psychologists Amos Tversky and Daniel Kahneman of the Hebrew University of Jerusalem coined for the first time In 1972 the idea of ​​cognitive bias psychologists such as Daniel KahnemanNobel Prize in 2002, were based on the work of Tversky and Kahneman To demonstrate The profound influence of this bias on business and personal decision making, being relatively easy to be trapped in that immobility situation. Richard Thaler presented for the first time The practical concept of the fallacy of the sunk cost, concluding that people have a greater tendency to use a certain good or service when they have previously invested money in them. According Research From the University of Ohio (USA), the fallacy of the sunk cost refers to the trend that people have to continue an activity or remain in a certain situation because resources have already been invested in it, although these resources are unrecoverable and the logical decision would be to abandon it. In labor decision making, falling into the fallacy of the sunk cost – or of unrecoverable cost – implies postponing indefinitely the decision to change jobs Just because we do not want to “lose” what has cost us to reach the current position. The bias in important decisions This thought error causes people to stagnate in jobs that do not motivate them and are even restricting their professional potential, even when there are evidence of other more beneficial and rational options. The bias is based on a determining psychological factor such as loss aversion. For example, the personal feeling of responsibility for the resources already invested, or the fear to seem like a “wasteful” to others, can make someone stay years in a job that no longer provides satisfaction or professional growth. In Psychological researchit has been proven that the change of work is postponed, although the alternative is clearly better. This paralysis is produced by this aversion to the psychological loss that supposes that all the effort made in the past has fallen into a broken bag. Trapped in their own trap A study carried out by the researchers at the University of Kansas with more than 1,000 participants showed that, who fall into this fallacy, have greater symptoms of anxiety and postpone the search for professional help. Recent research From the Department of Psychology and Economics of the University of California in San Diego, they reflect that “the fact that you have dedicated unrecoverable resources to a project does not mean that you have to sink with the ship,” said their authors. The scientific evidence It reveals that, to avoid making irrational decisions, it is essential to identify this cognitive bias and learn to make decisions based on objective data and future possibilities, not in what has cost you to reach the point where you are. Recognizing the fallacy of the sunk cost is the first step to overcome it In labor decisions. If this awareness does not occur, there is a risk of continuing to invest resources, even more intensely, falling into a vicious circle that will be increasingly complicated to leave. Such and as they highlight From Asana, it is important not to get carried away by immobility and make decisions based on objective data and take an external perspective, not get carried away by fears and investments of the past.

Threads is eating the toast to X. He is doing it without making noise and with some data that already starts to weigh

by

Not all the mountain is oregano and not all text -based social networks are X. After the Elon Musk arrival at xthen Twitter, there were few users who fled from the bird’s social network in search of more green pastures. It was then that Mark Zuckerberg, Meta CEO, opened the doors of his: Threads. Two years They have passed Since then and the platform has grown to become a powerful X rival, one that already begins to stand up. The data. As confirmed yesterday Zuckerberg and Adam Mosseri (Instagram CEO) In its official profiles, Threads has managed to reach 400 million monthly active users. It is a significant figure, especially considering that they closed 2024 with Something more than 275 million users that in April the amount amounted to 350 million. 23 Twitter tricks – This social network is completely dominated! Monthly active users (MAU) are a key indicator to quantify the performance, state and health of, in this case, a social network. This metric measures the number of unique users who have visited the platform at least once during the past month. That the Mau grow is a good sign. And what about X? The only information related to X we have in some of the latest statements by Linda Yaccarino, which until a few weeks ago was the CEO of X. According to YaccarinoAs of April 2025 x, it had 600 million monthly active users. The growth was, however, softer. In September 2024 X it had 570 million Mau that, in January, became 586 million. That is, in general terms X it has more monthly active users than Threads, but the growth of Threads is much higher. On the other hand, it is also evident that Threads has more growth capacity than X, a social network that Elon Musk apart, already showed signs of having touched the roof when it was Twitter. Anyway, they are data that must be taken with tweezers because in both cases the source are the ceos of the platforms and, therefore, interested parties. A matter of use. However, there are more third -party data that support the growth of Threads. According to SimilarWebThreads and X have a very similar amount of daily active users (Dau) in their mobile apps: as of June 2025, the X and Android apps had 132 million Dau (15.2% less than the previous year), while Threads added 115.1 million (127.8% more than the previous year). The photo is very different if we look at the use of the websites, with X adding 145.8 million daily visits and Threads only 6.9 million. On the other hand, and according to Apptopia data Shared by Sheel MohnotThreads wins X in another key metric: the engagement. Threads users enter the app 6.6 times a day and each session lasts 190 seconds, while those of X enter 7.3 times and 150 seconds pass. This, in other words, means that Threads users spend 21 minutes daily using the app, while X spends 18 minutes. Threads has fewer users, but those who have them retains them for longer. Threads has a large user tractor: integration with Instagram THE ALMENDRUCO trick. It is no secret that goal has made Threads grow based on integrating it with one of the great titans of the industry of the industry of the doom scrolling: Instagram. IG users see some THREADS posts in their feeds, they can interconnect both profiles and even receive Instagram Push notifications with Threads content. Goal has its weapons and is using them quite intelligence. And Bluesky? Another of the most popular alternatives is Bluesky. After growing greatly at the end of last yearthe platform currently adds 38.2 million registered users, although its real activity is much lower than that of X and Threads users. According to the data of your own API, you have between 600,000 and 700,000 users publishing content and around 1.2 million interacting with the posts. At the moment, it still does not shade the proposals of Meta and X. Cover image | Xataka In Xataka | Bluesky and Fediverso want to stand up to the goal. These are the alternatives to Instagram that are already on the table

The residents of Madrid had been yearning for the Soterramiento of the A-5. Now he is making his life impossible

by

Without water, without light and without internet. These are the inconveniences that some residents of the neighborhoods of Aluche or Batán have had, next to the supporting works of the A-5, the highway that will disappear under the feet at their entrance to Madrid. But also continuous traffic jams, a firm proof of SUVs and, in summary, inconveniences that promise to stay for years. And that affect far beyond the residents of the area. The last claim. Alcorcón, Móstoles, Arroyomolinos or Navalcarnero are just some of the municipalities directly affected by the Soterrament works of the A-5. Every day, about 80,000 vehicles, According to data from the Madrid City CouncilThey access the city in this way. Obviously, putting a plug in the entrance in the form of a mega -Obra has caused overflow. The overflow to roads and adjacent streets but, above all, has overflowed the patience of the residents of these municipalities who ask that Four winds military land are opened (without use) to take advantage of them as deterrent parking lots. Why four winds? This neighborhood with a subway stop and Cercanías has become the nerve point of the entrance to Madrid. If everything goes correctly, It has a connection with Atocha In about 20-25 minutes. Yes, as we said, everything works correctly. Currently, this area has been reserved as a hot point so that the buses that were as destination Principe Pío or elliptical square and entered through the A-5 left the travelers and cease their trips. A decision that, in the first days, caused huge chaos. Daily jams. The underground has evidently caused that the traffic jams multiply in the area. Of the three or four lanes (depending on the area) that had so far available in each direction, Only two are operational. And, while the underground works are carried out in a sense, the vehicles circulate through the opposite section. The initial plan He was going to maintain the works for at least 25 months. However, the project has ended up expanding to the connection with the M-40 which Expand the stretch of works in another 700 meters. It was a claim of the neighbors who were assured that this would take place at first and, nevertheless, The idea had been discarded When the machines began working in the area. But the condition goes far beyond the jams. Without light. May 12, 2025. Batán neighbors spend part of the morning in the dark. Some 4,600 subscribers to Iberdrola see the light of their homes and businesses cut due to a fault caused by the accidental cut of a cable that travels through the area affected by the underground. Without water. May 19, 2025. As soon as a week passes when Aluche’s neighbors have problems of light and water in their homes and businesses again. This time the condition was recorded at 11 at night. They distributed pallets with bottled water to pass the bad drink in what the fault lasted. The reason: a stoopy pipe. Without internet. July 7, 2025. The most recent condition. The error this time takes a fiber optic cable in the works which leaves Movistar subscribers without internet in Aluche and part of Pozuelo, a town located on the other side of the country house, with which they border the works. The fault was not solved until the next day. A little hell. Yes, in Xataka We know that some neighbors have suffered the plenary of breakdowns and have been found without light, without water and without internet in less than two months. To this we must add, as we say, the usual traffic jams in the area, the cut of some steps that lightened the paths (as the departure to Boadilla from Seseña Street) or a very deteriorated firm that is suffering the passage of heavy machinery. The promise of a better place should give some hope to neighbors. Similar works made reborn what is now known as Madrid Río, a huge park with which Madrid won 120 green hectares and 30 kilometers of cycling paths. In addition, the square meter was revalued at 500 euros. Of course, for those who live in the surrounding municipalities, the improvement will only enjoy it if they express stop in the area once it is finished.

Some researchers believe that AI is making us more dumb. We have listening the same from the calculator

by

The AI ​​is making us dumb. A recent study has revived an old fear: that of technology by decorcing our cognitive abilities. It has happened with writing, calculators, television or internet. With the irruption of Great language modelsAI is in the center of the debate, but does it really make us more dumb? A MIT study. A few days ago a study conducted by MIT researchers About the “cognitive cost of using chatgpt in the educational context of writing an essay.” In the study, which lasted four months and had 54 participants, they wrote an essay a month while monitored by electroencephalography. The participants were divided into three groups: one used chatgpt, another used the search for Google and the third did not use any tool. The group that used Chatgpt gave the worst results in brain activity and also became more lazy with each essay they wrote. It has logic. If we use a tool to do a homework for us, the natural thing is to stop doing that task manually. Thanks to the calculators we no longer need to do great operations by hand. Having a GPS we arrive at our destination without having to memorize the route and with a search engine like Google it is no longer necessary to know by memory all the rivers of Spain. With the AI ​​we already saw how Some programmers no longer know. The key question that arises is: does this dependence imply a real decrease in our intelligence? A historical fear. It is not the first time that we fear that a new technology will become less intelligent, in fact it is a constant fear throughout history. In the 370 AC, Socrates already questioned if the writing was weakening our ability to memorize (the funny thing is that he did it In a book). With the pocket calculators came the fear that we forget to perform math operations by hand. A fear that It was fulfilled (Who makes divisions by hand having calculator?), But that does not mean that we are worse in mathematics. In fact, this Meta analysis He concluded that calculators do not negatively affect performance and even improve the attitude towards mathematics. Technology and brain. For years we wanted to know the effects of new technologies on our brain and television has been in the spotlight. In This studythe researchers verified how seeing films our brain entered a mode of “low demand” similar to that of deep sleep. In This other study They conclude that seeing a lot of television is associated with a lower volume of gray matter. Something similar concluded This study about the effect of playing a lot of video games. The Internet was a radical change in the way we access information. In This 2011 studythe ‘Google effect’ was coined or how, when we know that we can access the information whenever we want, we tend to memorize less specific data. Instead, we remember better how and where to find that information. Without clear evidence. Studies that say that technology makes us dumb either lazy There are many, but there are also others who claim that There is no clear evidence that it is so. The appearance of new technologies changes the way we entertain ourselves, we look for information or work, but that does not necessarily imply that there is long -term damage in our cognitive ability. The comparative advantage. The theory of Comparative advantage It was developed by David Ricardo in the early nineteenth century in the context of international trade and is defined as the ability to produce a good or service at a lower opportunity cost than others. In his Column in The Free Presseconomist Tyler Cowen applies this theory to the IA issue. The opportunity cost in this case is the time and energy that we dedicate to a task or, as they say in the study of MIT, the cognitive cost. Less effort does not mean more silly. Following the concept of comparative advantage, memorizing the capitals of all countries would mean a high cognitive cost, greater effort. Here the AI ​​would have a comparative advantage over us because its effort is almost null. On the other hand, when performing more creative and analytical tasks, such as writing an essay on geopolitics, we have the comparative advantage. We can interpret it as if it reduces our capacity, or we can interpret it as AI is an assistant who deals with more repetitive tasks so that we can focus on the most important. It is not the AI, it is we. Returning to the analogy with the calculator: it is not the same to use it to make complex operations than to depend on it to add 1+2. Obviously, what chatgpt does Little has to do compared to the calculator. The abilities of language models are infinitely higher and the risk to depend too much on it for too many things It is very real. However, There are psychologists who affirm That the impact on our intelligence will depend on the use we make of it. As the psychologist Jason Lodge says in This great articleAI is the electric bike of the mind. To close, the best example I can give you is this article. Reading all the studies that I have cited and draw conclusions would probably have taken more than one working day. What I have done is ask Gemini, Chatgpt and Perplexity to summarize some of these texts. It has helped me to understand everything better and faster. Or I could have asked for That the whole text and copy it literally And I wouldn’t have learned anything. Image | Gemini In Xataka | Chatgpt is taking some people to the edge of madness. Reality is less alarmist and much more complex

Patients lead to the operating room photos of their “improved” with AI. Surgeons are in charge of making them come true

by

A year ago, an unpublished contest copied The covers of different media: Miss Ia. As one can intuit, the models were created with artificial intelligence and presented impossible bodies: without wrinkles, without pores, without history … the event, promoted by the platform Fanvue World AI Creator AwardsNo only generated a flood of comments, but opened a deep debate: are we willing to accept something of beauty as an ideal that does not even exist? And something further, does the real body begin to be seen as a defective version of the digital render? Unreal expectations. According to The Columbus Dispatchplastic surgeons such as Dr. Jaclyn Tomsic and Dr. Craig Lehrman are observing a worrying phenomenon in their consultations: patients who come with images generated by AI, asking for impossible interventions. “With AI you can make your body as you want,” explained Tomsic, maxillofacial surgeon in Cleveland. For his part, Lehrman, a plastic surgeon at the Wexner Medical Center of the Ohio State University, has reported cases of older patients who carry photos of edited celebrities. “They tell me: ‘Why don’t I look like this?’ Both doctors have recognized that they have had to dedicate more and more time to explain why they cannot replicate what IA promises: biology, bone structure or age cannot be erased with scalpel. Beyond. The expectations created by filters, apps and image generators They are generating Frustration and danger: some people insist on operating again and again, chasing a non -existent ideal. In addition, they have warned of a psychological risk: people who fail to resemble these artificial images can become obsessed, resort to multiple surgeries and face constant frustration. Lehrman has summarized it as follows: “That will take many unhappy people and pursue this imaginary dream.” In fact, this phenomenon goes beyond the surgical: it affects the way we interact with our own image. It is increasingly common for people to ask AI that value their physical appearance Or tell them what to improve on your face. The point is not what the AI ​​can respond, but the fact that your judgment has so much weight on how we can perceive. Fiction made leather. Before, manipulating an image required technical knowledge or tricks of light and makeup. Today, with a free app, anyone can be seen as a supermodel in seconds. The AI ​​not only retouches, but has led it to another level: it can generate faces from scratch. According to Lehrmanthis makes it “increasingly difficult to distinguish the real from the invented.” Given this threat, the American Society of Plastic Surgeons has created a gallery with real photos before and after procedures to combat misinformation. But the battle is unequal: millions of false, stylized and standardized images are generated every day. The Aitana case. This logic is reflected in phenomena such as Aitana LópezSpanish influencer with more than 350 thousand followers on Instagram that does not really exist. In other words, it is a 100% model generated with AI. Its creators They have admitted They sought to create an influencer that “never gets tired, never ages, always smile.” With his success, he has not only obtained real advertising contracts; It has also imposed a new quite problematic aesthetic standard because there are no human limitations. Advances and dilemmas. The “artificial intelligence in plastic surgery: where do we stand?” has reviewed 96 Studies on the use of AI in plastic surgery. Although it has proven useful in diagnoses of dermatological diseases, surgical planning and even prediction of postoperative complications. However, the conclusions have also warned about ethical risks, lack of regulation and algorithmic biases. One of the key problems is that AI models are trained with limited populations data, which can generate racist, class or capacitist results. The bias behind the AI. The algorithms are trained with millions of images that reinforce Eurocentric, thin, cis and young people. As has warned Kenig et al. Quoted in the study, AI can exacerbate inequalities by replicating stereotypes invisible other bodies. This concern has also been pointed out by critical voices within the technological field. For example, author Ruha Benjamin holds that “Algorithmic discrimination does not need hate to function; You only need data from the past ”, in his book Race AFter Technology. For his part, Safiya Noble, in Algorithms of Oppression, has detailed How commercial and racist logic are embedded in search engines and recommendation systems. Technology, far from democratizing beauty, seems to strengthen it even more. The definition of beauty is not so much. As Bell Hooks said: “Representation matters.” However, if now the AI, trained with exclusion patterns, decides what faces we see, what bodies are shown, and which do not, then we are not only attending an aesthetic change, but to a deep reconfiguration of what we consider desirable, possible and human. The issue is not asking: “What is beautiful?”, But what are we willing to obey?

While NASA faces the cancellation of 41 missions, China is making authentic virguerías in space

by

The Tianwen-2 probe is the first of those launched by China with ionic propulsion. Not only is it on the way to a nearby asteroid to bring samples to the Earth: its one -decade trip also includes exploring a main belt kite, as far as a Chinese ship will have arrived. China does not give truce. Just when NASA expects 24% of its budget cuts and the cancellation of 41 space missions, China has launched an extraordinarily ambitious scientific program that will take it throughout the solar system throughout the next decades. Robotic Tianwen missions, which are just part of these plans, focus on exploring and bringing samples from other worlds. Tianwen-1 deployed on May 22, 2021 The first Chinese rover on the surface of Mars. Tianwen-2 will bring the first samples of the Kamo’oalewa miniluna at the end of 2027. Tianwen-3 will take advantage of what has been learned In previous missions to bring Martian soil samples, a milestone that the Chinese Space Administration Wait before the United States. Tianwen-4 will explore Jupiter and one of his moons. Double objective. The Tianwen-2 probe took off on board a CZ-3B rocket from the Xichang space center on May 28. After successfully deploying its circular solar panels and performing an escape maneuver, it is directed to Asteroid 469219 Kamo’oalewawith which it will be found for the first time on July 4, 2026, and that will explore closely until April of the following year. In November 2027, after releasing the reentry capsule with asteroid samples, Tianwen-2 will continue on its second goal: 311P/2013 P5 (PANSTARRS). It is a main belt kite, an active object with the orbit of an asteroid and the appearance of a kite that the Chinese ship plans to reach in 2035. Crossing outstanding tasks. To achieve its objectives, Tianwen-2 will not be the first space mission to bring samples of an asteroid (Japan has done it twice and The United States got it in 2023 With Asteroid Bennu), nor the first probe to explore a comet (the European Space Agency landed in Comet 67p in 2014), but the first to do both. China’s space administration is taking advantage of its previous experience to continue crossing outstanding tasks of the list: the Chang’e 2 mission visited an asteroid in 2012 and the Chang’e 5 and Chang’e 6 They brought samples of the visible face and the hidden face of the moon, respectively. When moving so fast, China begins to advance the rest of the nations in some of these milestones, as in the case of samples of the hidden face of the moon. What are these objectives special. Tianwen-2 will not only serve to prepare the recovery of Mars samples. Kamo’oalewa is an interesting object in itself for being a minilun It can be a fragment of the true moon. Tianwen-2 will deploy two small robots: a nanoorbital and a nanoatrizer that will make detections closely. Then, without landing, you will take asteroid samples with an extensible tube and a small excavator wheel to bring them to Earth. Next, it will take advantage of the gravitational assistance of the Earth to travel to the strange comet, which in photos of the Hubble telescope appears with six queues. It will be the Chinese probe that best moves away from the Sun until the arrival of Tianwen-4 to Jupiter. A second probe, launched at the same time 2029, will arrive in Uranus in 2045. But China plans to go further with two missions to Neptune, whose launch is scheduled for 2029 and 2033, with the difference that the second would display an atmospheric probe on its Triton moon.

Overcoming our brain when making the purchase is not easy. Some researchers have developed a tool to achieve it

by

“Codazo theory.” It’s how we could translate Anglo -Saxon expression, “Nudge Theory”, Which refers to the study of actions focused on giving us A “little push” Towards a specific decision. The concept is especially used in the context of the behavioral economy, That place where the economy is mixed with psychology. We know that companies often resort to these “pushcins” to lead us to purchases that generate more benefits but can we use this tool to improve health? Digital tool. The answer is yes, and there are many researchers who work to develop this type of tools. The last It has been developed By a team of Duke-Nus Medical School and it is a digital tool that aims to facilitate the task of choosing healthier products in our purchase on-line. An imperfect system. Choosing healthier food products is not always easy. Yes, we can always make sure that our purchase car is full of fruits, vegetables and other basic foods to cook at home, but this option is not always realistic. Labeling systems such as Nutriscore They can help us choose better, but they have Important limitations. The first is that evaluating the healthy of a product in a simple index is not always easy and sometimes leads us to important inconsistencies. The second, that this index must compete with marketing strategies that seek to buy a product, regardless of how healthy or ceases to be. Beyond labeling. To exceed these limitations, Duke-Nus’s team designed a digital tool destined to facilitate a purchase on-line better informed at nutritional level. This tool complemented the information available on the Internet purchase page, adding additional information. This additional information included a traffic light based on the index Nutriscore of products, complemented with other tools. First, the page ordered the products based on this index, first showing the healthiest products instead of doing it alphabetically. Second, the tool incorporated the follow -up of the products in the purchase car, indicating what proportion of food was labeled as green, yellow or red. Third, the digital tool also showed healthy alternatives (with similar prices and characteristics) to selected products. Studying alternatives. The team tested the tool through an experiment. They asked a group of participants to make three purchases on-line over three to six weeks. Some of the participants used this tool, while others used the conventional portal. The team observed that the purchase cars of the people of the intervention group scored better in the nutritional index. They also contained less calories, less fat in total and less saturated fats, less sugar and less salt. The details of the study were published In an article In the magazine American Journal of Preventive Medicine. Public health issue. By will or necessity, there are many people who seek to eat healthier, and that begins in a healthier purchase. Achieving it for oneself is not easy, but it is not to help these people without falling into prohibitions and Tax Methods. Here is like the behavior economy and Nudge Theory They can help us: the same tool often used to take us to more advantageous options for sellers can also be used to improve the health of consumers who wish to improve their diet.

12 years after making fun of Spacex and his idea of ​​landing rockets, Arianegroup is creating a European mini-falcon 9

by

Year 2013. An Arianespace manager gives his opinion on Spacex in a symposium in Singapore. His statements still resonate in the European space industry as a summary of the 10 or 20 years lost that now, Arianegroup and the European New Space They are trying recover. “They will wake up.” The question was: how Arianespace will compete, the French company that has been launching all the rockets of Europe for 40 years, with the launch of 15 million dollars that Spacex promises. This was what Richard Bowles repliedDirector of Arianespace in Southeast Asia: “They are progressing incredibly well, but what I see in the market is that Spacex seems to be selling mainly a dream. We should all dream, but the releases of 5 million or 15 million dollars are a dream. And personally I think that reuse is a dream.” “I feel that the question is how I am going to answer a dream. And my answer to answer a dream is’ do not wake up people, they have to wake up on their own.” “They are not superhombres, whatever they can do, we can do it too.” The awakening. Breaking a spear in favor of Bowles, very few would have opted for Spacex in 2013, much less a corporation with the European launch monopoly. By nature, large companies have risk aversion and cannot maneuver with the agility of a startup. However, time gave Elon Musk reason. In 2024, Arianespace launched three rockets: A Ariane 6, A Vega and a Vega-C. Spacex, meanwhile, launched 132 Falcon 9 and two Falcon Heavy. He also beat the reuse record with 26 launches and landings for the first stage of a Falcon 9. Themis project. Arianegroup began to maneuver in 2019 at the request of the French space agency CNES. ARIANEWORKSa collaboration between the two entities, announced the development of a multipurpose rocket of low cost and reusable, known as theomis project. The project received 33 million euros of initial financing. Although the first jump test (a vertical flight of low altitude) was scheduled for 2023, It has been delaying. Themis will merge with another rocket that has ended up being more promising. A rocket called Maia. In 2022, Arianegroup founded Maiaspace, a subsidiary that, this time, would work as a startup.

France puts Apple a fine for making advertisers difficult. The problem of the fine is that it is symbolic

by

Apple It has been fined with 150 million euros By the Fancesa regulatory authority, I authorized her in the concurrence. The sanction is due to its dominant position between 2021 and 2023 in the advertising segment in mobile applications. It is the first fine that an antimonopoly regulator issues Apple by the call Tracking transparency app (ATT). This technology is supposed to prevent apps from tracking us more than the account. In iPhone and iPad ATT it allows users to decide which apps can monitor their activity. However the system has been criticized by advertisers And for Apple’s rivals –With Facebook as a great example-, to which it harms by depending on that online advertising. In fact, the investigation that has ended up causing this fine comes from the complaints of Several online advertisers associations and also of Internet suppliers who accused Apple of abusing their privileged position. The French regulatory entity indicated in a statement that “although the objective pursued by ATT is not critical in itself, the way in which it applies It is not necessary or provided to the declared objective of Apple to protect personal data. “ In fact, the statement also stood out as ATT “particularly penalizes small advertisers”, who depend largely on third -party data for their business. The fine, of course, is much smaller than the European Union imposed on Apple last year for Spotify demand for “limiting options and drowning innovation.” Then The fine was 1.8 billion euros. Apple has indicated that it was disappointed with the fine, and that the French regulator has not specified what changes should make for its privacy control tool. The ATT system is also being investigated by the regulatory entities of Germany. The fine, as we say, is almost symbolic, especially if we compare it with what the EU imposed last year. Even so, this could return to Increase existing tensions with Donald Trump’s governmentwhich in recent weeks has begun to launch tariffs that raise a global commercial war and that of course They significantly affect Europe.
