Einstein told us how to do it, engineering tells us it’s almost impossible

After the success of Artemis IIscience already has its sights set on the colonization of the Moon or Mars. The problem is that, for this to be possible, it would be necessary to develop technologies that do not exist today. For example, you can spend a short time under the effect of microgravity, but if someone wanted to spend very long stays in space, much longer than those of the International Space Station, they would need artificial gravity generation systems. If not, your health could seriously deteriorate. And how is that gravity generated? Theoretically we know it, the problem is getting it. Einstein gave the first clues. In his Theory of Special RelativityEinstein described something known as the equivalence effect, which stated that gravity and acceleration are indistinguishable effects when they have the same value. That is, since the force of gravity on Earth is 9.8 N, equivalent to an acceleration of 9.8 meters per second squared, if an astronaut traveled in a spacecraft that ascends with an acceleration of 9.8 m/s², he would feel his feet clinging to the ground, even without gravity. For this reason, all theoretical projects to create artificial gravity are based on this principle. Too much fuel. One option would be the example we have seen. A rocket accelerating at 9.8 m/s². The problem is that to maintain this figure constantly unfeasible amounts of fuel would be needed. It is not something feasible. Better spinning. Given the technical impossibility of the first option, all projects aim at centripetal acceleration. That is, the acceleration that a rotating body maintains. If we were inside a ship that rotates with a centripetal acceleration of 9.8 m/s², we could imitate gravity. But there is a problem. Centripetal acceleration is equal to angular velocity squared times the radius of the spin path. As if it were the spoke of a bicycle wheel. Angular velocity is the speed at which that object rotates. If the radius is small, a very high speed is needed to achieve a given acceleration. And of course, the people inside that circular ship would end up very dizzy. On the other hand, in very large ships it would not be necessary to turn so quickly. Therefore, for a small ship it would not be viable, but perhaps something like this could be achieved if a new space station is built in the future. In fact, There is a project to build a luxury hotel in the space that would be shaped like a giant wheel. It would be constantly spinning, with the exact radius and speed to mimic the effect of gravity. Doesn’t anyone think about the Moon? The objective of lunar bases is that their inhabitants can be directly perched on the selenite surface. The same would happen with the Martian bases.. They would have to be on the surface. Therefore, it would not be viable to be inside a flying wheel. On the other hand, a wheel could be built to which the lunar colonizers would go from time to time. Just enough to reverse to a certain extent the harmful effects of microgravity. It would be like a kind of microgravity spa. This is something that a team of scientists from Kyoto University has already designed. They have named it The Glass. The consequences can be very serious. When we are not subjected to gravity, body fluids can travel to the headcausing brain inflammation and vision problems. This also affects the circulatory system, as it can increase pressure in specific vessels, such as the jugular vein. Even the heartbeat would be affected. On the other hand, by not needing to be in a rigid posture, the muscles gradually atrophy and the bones lose density. All this without counting possible neurological, balance or intestinal problems. Long stays in a microgravity situation are unfeasible, so it will be necessary to have a clear project to develop artificial gravity. If we want to live in space, we will really need it.

Is it the best time to buy a Poco F8 Ultra or should you wait? This is what the data tells us

by

Depending on how the price of the Poco F8 Ultra since its launch and seeing how its predecessor (the Poco F7 Ultra) in the market, this is how we evaluate whether or not to buy the F8 Ultra, in its 512 GB versionwhich is the one we have analyzed. 🟡 CAUTION (WAIT FOR OFFER) Poco F8 Ultra Verdict It is a mobile that has been on the market for a short time and can still be purchased almost at a launch price official RRP 899.99 euros (Xiaomi official store) Target price “on the street” Don’t pay more than 699 euros (Amazon in the 12 GB RAM version) Next release Next Poco F9 Ultra expected to launch in Q1 2027 according to rumors Our recommendation Wait if… If your current mobile still holds up and you are not looking for the bargain of the century, wait a few months (June/July), since the price of the Poco F8 Ultra will have stabilized and you will be able to get it cheaper. Regret cost Medium (about 100 euros). Normally, Poco lowers its terminals when they have been on the market for more than half a year.

We earn commission from these links Why is the traffic light yellow? Although the Poco F7 Ultra started with a starting price much lower than that of the Poco F8 Ultra, it is true that its history serves to suggest that, currently, it is a favorable time for wait for it to go down. Specifically, we find ourselves in this situation: A relatively new mobile: With only about three months on the market, it is normal that the price of the Poco F8 Ultra remains stagnant. The ideal is to wait for it to go down, when it has been on the market for a little longer. Future purchase: Waiting means being patient and seeing the different offers that may come out for this mobile (we are aware of them and we will offer them to you).

Expert Buyer Tip: That the Poco F8 Ultra is a knockout is something about which there is no doubt. Although buying it now for almost the same price as the original price is a financial mistake. If you hold out for a couple of months, you will be buying the same hardware for the real price it should be. Price history and change prediction The graph above compare the prices that the Poco F8 Ultra has had compared to its predecessor (the Poco F7 Ultra) over a year. These are the data that we get in key from this graph: The Poco F8 Ultra has had a aggressive debutpositioning itself significantly above the historical figure of the F7 Ultra (reaching 899.99 euros in month 8). While the previous model (F7 Ultra) maintained notable stability between 550 and 600 euros, the new flagship shows much greater volatility, with rapid corrections of 150 euros after price spikes. The current trend suggests that the F8 Ultra will seek to stabilize around 749.90 eurosa price floor that is still 36% above what its predecessor cost at the same point in the life cycle. If you are looking for the real ground, the prediction indicates that you will have to wait until the last quarter of the cycle to see figures close to 600 euros.

Is it a good time to buy the Samsung Galaxy S25 or will it drop in price? This is what the data tells us

by

According to the price that the Samsung Galaxy S25 since it was launched and seeing how its predecessor (the Galaxy S24) performed in the market, this is how we value, at the moment, the purchase of the S25 in its 256 GB versionwhich is the one we have analyzed. 🔴 alert (don’t even think about it) Samsung Galaxy S25 Verdict At this moment it is almost at its launch price official RRP 869 euros (Samsung store) Target price “on the street” Don’t pay more than 729 euros (Powerplanet) Next release You can now buy the Samsung Galaxy S26 at the official price of 999 euros in the Samsung store. Our recommendation Don’t buy it. After having reached its historical minimum, now this Samsung mobile is practically at its launch price, being a moment in which you will pay 200 euros more than two months ago for a terminal that is already more than a year old. Regret cost High. The mobile phone has been on the market for more than a year and has a successor. Buying it now would be throwing away your money, as it is expected to drop back to the lowest price it reached a few months ago. In fact, it is already starting to decline in some stores, but not at a considerable rate. Samsung – Samsung Galaxy S25 12GB + 256 GB free mobile. The price could vary. We earn commission from these links Why is the traffic light red? The price of the Samsung Galaxy S25, in March 2026, has reached a critical rebound situation after more than a year on the market. That is, the price went down after its release, but now it has started to rise suddenly until almost reaching its initial selling price. Therefore, we find ourselves in this situation: Uncertainty after the launch of the new Galaxy S26: After reaching its maximum price peak again, we now have to wait for the Samsung Galaxy S25 to drop again after the recent launch of the S26 (something that already happened to the S24). Everything indicates that in a few months the Galaxy S25 will drop and its price will stabilize. Future purchase: This means that, at the moment, the purchase of the S25 is more on impulse, since there are really no good offers for this model. The ideal is to wait a few months in case you want to get the previous generation of Samsung’s flagship. Expert Buyer Tip: The Samsung Galaxy S25 has suffered a “bullwhip effect” in recent months and its price has skyrocketed. With the launch of the new Galaxy S26, the price curve will surely end up going down. So if you can wait, the price of Samsung’s previous flagship will eventually drop until it stabilizes. Price history and change prediction The graph above compares the prices that the Samsung Galaxy S25 has had compared to its predecessor (the Galaxy S24) over the course of a year. This is what we observe: This is how Samsung makes money: the secret is in the IPHONE Unusual instability: The S25 market is being totally unstable. While in months nine and ten it reached its historical minimum price (being the best purchase option). After this, it has experienced a rebound that places it almost at the launch price. It is more expensive than its predecessor: Right now, the S25 is 21% more expensive than the Galaxy S24 at the same point in the cycle. The recommendation, therefore, is none other than to wait. Drop expected: It has already been shown that the S25 can drop considerably, so buying it at the prices it is at now, at this point in the life cycle, is paying an unjustified premium for a model that already even has a new replacement (the Galaxy S26) on sale. The best Samsung Galaxy S25 deals now: Keep in mind that many of the offers we find are no longer available once we publish the item, either because they end or because stock runs out, so make sure before buying.

In the midst of the rise of streaming platforms, there are still many reasons to buy an Amazon Fire TV Stick or a Xiaomi TV Box. You may want to convert an old TV into “Smart” or you simply want to try another way of consuming content on that screen. But deciding that you want to buy one of these devices is just the first step. The next, and perhaps the most important, is to choose which one best fits what you are looking for. As with any other category of technology products, the decision is not always easy. Several factors come into play that should be evaluated before investing our money. And this is where the Xataka team comes in: we like to try things so you don’t have to. Ana Boriawhich already has thoroughly analyzed devices like the Plaud Note Pro either various smart watcheshas decided this time to put his television to the test to clear up any doubts. Two ways to bring streaming to your television In this Versus, our partner compares the Amazon Fire Stick and the Xiaomi TV Box in key aspects such as image quality. “If we talk about image quality, both devices support content 4K at 60fps“, in addition to being compatible with HDR 10+ and Dolby Vision content,” he comments. And that’s where the interesting part begins. If the two share these specifications, the question almost arises by itself: are there really reasons to choose one over the other? Ana’s tests go further and also address an aspect that for many users can make a difference: the installation of applications. “Last year Amazon announced that it would begin blocking some unofficial applications and even the download of APKs,” he explains, pointing out a relevant difference between both proposals. Now, the situation may not be as clear-cut as it seems at first glance, and in the video you will find the keys to understanding what is happening. The analysis also focuses on other important sections such as the operating system, connectivity or gaming, a field that is increasingly gaining more weight in this type of devices. “With both devices I have been able to install the applicationsconnect the controls and play, but I have not had a perfect experience with both of them,” our colleague advances.

On Amazon it is at a very good price (649 euros), but even at PcComponentes you can get it cheaper (619 euros) Regret cost Low. Although when the new Pixel 11 comes out the 10 model will drop in price, it may is not at a price as competitive as the one now offered by PcComponentes. At most you could lose 20 euros, since the Google Pixel 10 is not expected to drop below 600 euros. Why is the traffic light green? They have just passed six months since it was launched the Google Pixel 10 (August 2025) and there is exactly the same time left for Google to launch the new generation. This is a good time for those undecided who are hesitating between waiting for the new Google Pixel 11 or buying the one currently sold. For those who don’t want to wait, the Google Pixel 10 is one of the phones that has received the most offers in recent months (as we have covered in Xataka Selección). Now, with a price of 619 eurosit is one of the best prices at which the current one has been able to obtain Google flagship. Expert Buyer’s Advice: Once a few months have passed, do not buy the Pixel in the official Google store, because the price remains at the price the smartphone had at its launch. Better go to other stores that continually launch offers to get it. Price history and change prediction This graph shows a comparison between the price evolution of the previous model, the Google Pixel 9, superimposed with the trend of the current Google Pixel 10. These are our observations: The Google Pixel 10 has experienced a more aggressive price evolution if we compare it with the Pixel 9. The previous model went on sale for 900 euros and until the fourth month it maintained resistance in price. On the other hand, the Pixel 10 has experienced a price drop of 28% in just one semester, going from costing 900 euros to 649 euros. After a stable start, between the second and third month, the Google Pixel 10 dropped 150 euros and is now stabilized at 650 euros. This figure equals the all-time low that the Pixel 9 took almost a year to achieve. It can be said that the price that the Pixel 10 has now achieved is very competitivesince it has experienced a very rapid price drop and is expected to no longer drop further. Maybe it will reach 600 euros, but when the new generation Pixel is going to be released on the market. The best Google Pixel 10 deals now: For those looking for the Google Pixel 10 without waiting any longer, these are the best current options. Do not forget that, after our publication, the offers may expire or the stock may run out. Currently, the terminal is at very competitive pricesplacing it significantly below the 899 euros marked by its official rate in the Google store. The price could vary.

Time flies and, therefore, it is essential to know the details about what will be the successor to the current Google Pixel 10: Rumors about the Google Pixel 11: There are already leaks about the new Google terminal. It is expected to release a chip manufactured by hands other than the current ones: TSMC. Expected release date: If Google’s trend continues (consolidated with the Pixel 9 and 10), everything indicates that the official presentation of the Google Pixel 11 will occur in mid-August 2026, arriving in stores at the end of that same month. When will the Pixel 10 become “obsolete”?: Despite being one of the most supported phones on the market thanks to its seven-year life cycle, it is true that the launch of the Pixel 11 will introduce the new Google Tensor G6. This processor will be more powerful than the current one, making the Pixel 10’s hardware take a backseat. However, if you decide to buy the Pixel 10 now, you will not be purchasing an “old” model, since its performance will continue to be excellent even after the release of the new version.

Bringing fiber to rural Spain does not come cheap. This interactive map tells you exactly how much it cost

by

Those of us who live in urban areas take it for granted that we have fiber coverage, but there are many rural areas from Spain where fiber has taken a long time to arrive and even some where they are still waiting for it. To ensure coverage of the entire territory, the government launched subsidies for operators to deploy their network. Now we have a map to know the status of all deployments, interactive and non-profit. The map. It has been developed by Fernando García Álvarez, a software engineer who has contacted us to publicize his creation. It is an independent and non-profit initiative. Its objective was to gather all the information on fiber deployment plans, both the previous PEBA and the current UNICO plans in a single place, something that until now had to be consulted through various sources. His name is Fiber Programs and when we open it we find a heat map of the entire peninsula, with the red areas representing the areas with the greatest coverage and the yellow areas representing the least coverage. Detailed information. To obtain all the information on the different programs you have to zoom in and click on one of them. Here we can see which operator is carrying out the deployment, which plan it belongs to and other more in-depth data such as the total amount of the subsidy and the completion deadline. This is especially useful for those projects that are still underway because it allows you to know when a specific zone will be connected. Subsidies. That in 2026 there will be those who do not have a fiber connection is shocking, but there is a reason why there are still areas without this infrastructure: it is not profitable for operators to bring their infrastructure to an area where there are very few inhabitants. From this need was born the Broadband Extension Program or PEBA. The plan was active from 2013 to 2020 and subsidized almost 800 projects from more than 100 operators. In 2024, the UNICO Broadband plan took over the baton, with more than 18 million euros and with Avatel and Adamo as the main recipients of the aid. Spain and fiber. Although there are some areas left to cover, they are the least. The reality is that 95% of the Spanish territory has access to fiber optics, which places us well ahead of the European average, which is 64%. Our colleagues from Xataka Móvil made a devastating comparison: a town in Soria has better internet than Berlin.

The creator of the new Game of Thrones tells how to do something different

by

Yes, of course there was talk of ‘game of thrones‘. In the presentation of the new HBO Max news for 2026we had the opportunity to find out what awaited us from the platform’s most popular franchise in the coming months. We look at new images of the third season of ‘The House of the Dragon’, which will arrive in a few months, but above all, there was talk of the imminent premiere on January 18 of ‘The Knight of the Seven Kingdoms, an unexpected turn in tone and visuals for the franchise. A change of third that, if it proves anything, is that we have ‘Game of Thrones for a while’. ‘The Knight of the Seven Kingdoms’ is the third television project in the Westeros universe created by George RR Martin and is based on the short novels that make up the ‘Tales of Dunk and Egg’ cycle. They narrate the adventures of a wandering knight and his young squire located between ‘The House of the Dragon’ (72 years later) and ‘Game of Thrones’ (172 years before), in a time where the Targaryens still occupy the Iron Throne but the dragons are now only a distant memory. The protagonists are Ser Duncan the Tall, Dunk (Peter Claffey), a humble and tall knight, and his squire Egg (Dexter Sol Ansell), who actually hides his true identity as Aegon Targaryen, the future Aegon V. With a shorter and more concentrated format, with six half-hour episodes in its first seasonthe tone promises to be brighter and more adventurous, moving away from palace conspiracies and battles to focus on this journey through the paths of Westeros. And what we saw gave us the impression of an aesthetic identical to what we expect from the franchise, but with humor that borders on parody. This series serves to make it clear that there are many ‘Game of Thrones’ in ‘Game of Thrones’. We will see death, darkness and violence, but also gags typical of a sitcom. All while remaining a strong visual bet in the purest HBO style: costumes, photography and settings are on par with what we have seen in ‘The House of the Dragon’, and it is just as violent. A surprisingly talkative Ira Parker told us about all this, showrunner of the series. To make his own, distinctive version of the books, Martin says he did what the showrunners of the previous series did with the original work: “process it in your own style.” That is to say, “you are not looking for anything specific, the new style comes naturally according to your personality.” For example, Parker affirms that there is a lot of himself in the protagonistwhich “comes from the shittiest corner of Westeros.” What happens to him is that “all these princes, kings and queens he meets seem a little absurd to him. And he doesn’t really know if people are making fun of him or not, if they are serious or not. And from that situation many comedic scenes arise naturally.” And that’s why “this series is a good starting point for people who didn’t watch the original series because it was very dark. We take them by the hand on a lighter and kinder path to Westeros. And then it becomes the Westeros we know.” Because If there’s one thing fans don’t have to worry about, it’s fidelity to the original book. Parker says that from the first conversations with HBO and Martin himself, “the idea was that the story is the story. The story of these novellas, the beginning and the end, that’s what we’re going to tell.” But above all, respecting the original spirit: “That’s the fun of these books. Anyone can die at any time.” And also, according to Bloys, “with a final battle scene that is on par with what has been seen in ‘Game of Thrones’ or ‘House of the Dragon’.” And although Parker appreciates Bloys’ words, he makes a distinction: “the series identifies with Duncan to the point that everything, our music, our photography, our action and also our budget, is a reflection of someone who rises from nothing. Of course, there are great, very careful and epic series in this world. We are not one of them. We do what we can, like Duncan.” However, the heart of the series is not in the violence, but in “the relationship established between Duncan and Egg, which we have tried to take care of as much as possible. “We have two extraordinary actors who are basically good friends, that is, they became friends during filming, and we show that on the screen, we show a friendship that is forming.” In fact, he only has words of praise for the great discovery of the series, young Dexter Sol Ansell. He says it was the first audition for the character he ever saw, and he immediately wrote to the casting director: “I said, ‘Oh, perfect. He’s done it. He’s nailed it. What do we do now? Shall we hire him?’ and he said we had to go through a slightly longer casting process. We did, we ended up going back to that first audition. Dexter is a really special kid. He’s the best child actor who has ever lived on planet Earth.” In Xataka | George RR Martin asked ChatGPT to write ‘Game of Thrones’. He did it so well that he is going to end up before the judge

The Universe is already shutting down, and that only tells us what its end will be like.

by

Just like us, when we get older we leave the party behind and begin to lose energy, something very similar happens to the universe. And in the past the cosmos had a frenetic youth with an era known as ‘Cosmic Noon’10 billion years ago, where literally everything was a fireworks party with colliding galaxiesgas compressing and a great birth rate of our stars. But this party is coming to an end. With this simile, we come to the conclusion that the Universe is entering a great decline, as has pointed out a gigantic study led by the Euclid Collaboration that points out that the Universe is not only cooling, but appears to have stuck at a “retirement temperature.” How to do it. The question is mandatory, since understanding the health of the cosmos can be complex. That is why scientists choose to look at the ‘dust’ that exists throughout the galaxy and is the raw material for silicates and metals. with which the stars arise. The good thing is that this powder has a fundamental characteristic: it heats up. In this way, when many new stars are forming in a galaxy, a very intense light is radiated that heats up the dust that surrounds it. That hot dust, in turn, emits a weak glow in the form of heat: far infrared light, which is precisely what we can measure from our planet. Many tools. To make this measurement, a combination of observatories was used, such as Euclid, an ESA telescopewhich is creating the largest 3D map of the Universe and to do so provided an unprecedented census of 2.6 million galaxies. This information, together with old detections of far-infrared light, has been used to average the heat signal of thousands of galaxies of the same age and mass to obtain an incredibly precise average temperature reading. What it tells us. In this way, there is a direct correlation that tells us that a galaxy with its hot dust is a ‘factory’ of stars at full capacity. But a galaxy with cold dust is something that is already in decline and stable. The study confirms that in the “fever” of the Cosmic Noon, the galactic dust It reached average temperatures of 35 Kelvin (-238 °C). But as the Universe aged and star formation plummeted, that temperature began to drop. And this is where the key discovery comes. The study indicates that the temperature does not continue to drop indefinitely. After a certain point (8 billion years ago), the temperature stops falling and stabilizes. Specifically, it has remained ‘stuck’ at -249.95 °C. Because. What has basically happened is that the ‘thermostat of the Universe’ has changed from youth mode, where many stars were forming, to old age mode, where the dust warms up with the population of stars that exists, which is logically much colder. This finding is crucial because it shows that the temperature of the dust, for the first time, has become independent of the mass of the galaxy. It doesn’t matter if it is a large or small galaxy; If it is in our time, its dust is around 23 Kelvins, or what is the same: -249.95 ºC. Although 23 Kelvins is the new norm, it is just a pit stop on a much longer journey. This study is further proof that we live in a Universe in decline, dominated by dark energy that accelerates its expansion. In this way, as space stretches, galaxies will become more isolated and their raw material will be depleted. That is why the future (although we will not see it) is that the old stars that maintain this stable temperature are going to die. It’s like those embers that emit constant heat to be able to cook in the fireplace, which go out little by little until it becomes completely cold. The final destination, although billions of years away, remains the “Cold Death” of the cosmos: a state of maximum entropy where the temperature will reach Absolute Zero (-273.15 °C) and all activity will stop forever.

Are our works by removing us? That is one of the great fears What we have about the impact of artificial intelligence In society. The question is important and inevitablebut today there is no way to answer it with certainty. And it is not because we are not trying to do it. The AI ​​(say) is priming with the newly graduates In early August a reported report In The Atlantic He warned of something worrying: the unemployment rate among the newly American graduates was growing. Among the possible causes, a slow recovery was cited from the pandemic, but also a more disturbing one: that AI is used to solve the tasks that those newly graduates made in their first jobs. Wait, maybe AI is not replacing anyone. Shortly after, another study of the Economic Innovation Group titled with sarcasm “AI and works: the last word (until the next one arrives)” precisely raised the opposite situation. After analyzing several jobs theoretically exposed to the impact of AI, they detected that changes in unemployment rates were practically null or non -existent. According to those responsible, the AI ​​is not at the moment taking our work, and if it is doing, the impact is for now very small. A third study to liar more things. And of course the story did not end there, because a few days ago it appeared A new study led by the well -known academic and economist Erik Brynjolfsson. Here the research seemed to confirm the hypothesis of the first study cited: the AI ​​is impacting on employment, but not on the world: only in that of the newly graduated from the university. Young people have it more difficult, adults do not. According to their data, young people between 22 and 25 who start working as software developers or customer service agents They were having difficulty finding employment Because the IAS begin to occupy these positions instead. Thus, in the works most exposed to AI, these young people have seen 6% less employment, when other age ranges have increased the employment rate between 6 and 9%. On the one hand, the Economic Innovation Group study pointed out that there is hardly any impact between unemployment rates in theoretically expued work to AI. A difficult situation to explain. These three studies raise a confusing reality: is the work taking away, or not? Two of the studies do point to this focusing on young people who finish their university studies and look for a first job. Analyst Noah Smith contrasted That data and asked a question: how is it possible that companies are not hiring so many young people, but are increasingly hiring engineers of more than 40? There is a plausible, but not definitive explanation. On the other, the Brynjolfsson et al. (2025) reveals that the exhibition does exist, but only for the newly graduated young people between 22 and 25 years. The AI ​​as a complement to who knows and as a substitute for the one who does not. These studies that point to a real impact on the use of the youngest could be explained with a theory: companies are seeing that AI can in effect resolve “basic” tasks that the newly graduated, previously resolved, So there is a substitution effect. But they are also verifying that AI can also help workers with experience improving their productivity, so there is an effect of complementarity, of “co -pilot” of the worker. If that is true – and for the moment it is difficult to know – we have an important problem. Theories. Bharat Chandar, one of Brynjolfsson’s collaborators, explained In an independent article that “AI is exceptionally good in the type of knowledge that can be learned from books or that constitute the core of formal education.” But it also pointed to another possibility: that for companies it is easier to avoid hiring new employees than to let those already existing in an adjustment period that is affecting sectors such as software development. And now how I win experience? These first works of the newly graduated have always been crucial to gain experience and train in the professional field, but if AI begins to impact these jobs, the danger is that the quota of experienced professionals with experience It looks reduced. Companies will enter A dangerous vicious circle: If they do not form new employees, they will not gain experience that then serves to make them more productive. The possible transformation of the “first job”. This impact could break that cycle that we followed before to gain experience at work, but does not mean that there are no future options. In fact, you can make this experience gain accelerate. If companies hire newly graduated but they know how to take advantage of AI tools to learn and gain much faster capabilities, companies will have an opportunity on that scenario. Here correct and supervise the AI ​​- for example, so that it is aligned with the objectives of the company – and provide a creative resolution of problems assisted by AI can also contribute many integers in these young profiles.
