Reddit was one of the last refuge platforms for Internet users. You just took a step in a worrying direction

by

The social network Reddit has become the best source of human data on the internet. It is in fact one of the few remaining refuges from that “human network of networks” with which it all began, but this singular and anarchic social network has just taken a disturbing step: wants to force you to install their app when you use it from your mobile. uncomfortable notice. Millions of people use Reddit daily on their mobile, but in recent days they have encountered an uncomfortable message: a notice that forced them to use the Reddit mobile application instead of being able to continue using the browser to enjoy the famous thematic subreddits. There are many those who they have warned of the problem with diverse messages in the forums of the platform. In one of the most popular subredits, r/technology, the message that talks about the topic has nearly 20,000 positive votes and 4,200 comments. What Reddit says. Company spokespersons indicated at Ars Technica that Reddit has launched a test “for a small subset of mobile users that encourages them to download the app after visiting the site. These users are already familiar with Reddit and we have seen that the experience is much better for them on the app.” Personalization = data collection. The platform argues that if users take advantage of the app they can have a tailored news thread and better searches, but criticism has not been slow in coming. The Ars Technica editor who wrote on the subject himself commented how this notice has also reached him—not us, perhaps because we are not in the United States—and this sounds disturbing. And it sounds like that because it is just how apps like TikTok, X or Instagram work, which have managed to polish their content recommendation algorithms so that the user ends up condemned for doomscrolling. And that would point to Reddit’s ambition that we simply do nothing but be on Reddit. The danger of making your users angry. It is ironic that a platform like Reddit, which has always largely depended on the traffic brought to it by Google, decides to break with that way of reaching its forums. Those responsible for the platform seem to be confident that its content is essential enough for its users to convince them to download and use the app. The question is whether this will not cause an exodus of users. A small solution. Apparently is it possible avoid the message if we clean and we empty both the cache and the cookies of the mobile browser that we use to browse Reddit. This temporary patch can help you continue using Reddit directly from the mobile browser you use. Wall Street rules a lot. This apparent degradation or evolution of the service certainly seems to be aimed at maximizing profit. By going public, Reddit has to prove to shareholders that it can generate growing revenue. And if you can lock users into your official app, you can ensure that no one (including AI) can access that valuable content without going through your controls.

Europe and Japan step on the accelerator of nuclear fusion and place the ball in the court of a strategic country: Spain

by

Europe and Japan walk hand in hand towards nuclear fusion commercial. They have been working together for several years in the JT-60SA experimental reactorthe largest magnetic confinement fusion energy machine that currently exists. However, this is not the only project in which they collaborate. They are also fine-tuning the LIPAc linear particle accelerator (Linear IFMIF Prototype Accelerator or IFMIF Prototype Linear Accelerator). This machine resides in Rokkasho (Japan). After having undergone a very ambitious update, it is ready to begin the final phase that will conclude with its commissioning in 2027. Its purpose is to test the limits of particle beam physics to pave the way for future fusion reactors. Europe and Japan began developing this 36-meter-long particle accelerator in 2007 with the aim of validating the design of an IFMIF-type machine (International Fusion Materials Irradiation Facility) capable of acting as a neutron source. To achieve this, this device had to recreate the intense irradiation conditions that occur inside a fusion reactor. One of Europe’s most important contributions is a huge steel cryostat with magnetic shielding and a thermal shield that houses a powerful superconducting radio frequency system. This component serves to accelerate protons and deuterium nuclei until they reach a maximum energy of 9 MeV (megaelectronvolts), which will place them close to the high-energy neutrons that future commercial fusion reactors will produce. LIPAc is the precursor of IFMIF-DONES, which is already being built in Spain The knowledge that scientists hope to gain from LIPAc will be used in the development of IFMIF-DONES (International Fusion Materials Irradiation Facility DEMO-Oriented NEutron Source), that is already being built in Escúzar, a town in the province of Granada. The heart of this facility is a linear particle accelerator that will cost approximately 450 million euros, although the Government of Andalusia will provide half of this money. However, this is the cost of the accelerator; The entire IFMIF-DONES project will cost around 700 million euros. Spain will contribute half of this capital. IFMIF-DONES is one of the three fundamental pillars of the nuclear fusion edifice in whose construction the European Union is involved. The other two are ITER (International Thermonuclear Experimental Reactor) and DEMO. The experimental nuclear fusion reactor that is currently being built in the French town of Cadarache aims to demonstrate that fusion at the scale that man can handle worksand also that it is profitable from an energy point of view. However, ITER does not aim to produce electricity. That will be the task of DEMO (DEMOnstration Power Plant), a facility that will take the technological advances that have been proven to work correctly at ITER and take them one step further to establish itself as the true precursor of commercial nuclear fusion reactors. However, without IFMIF-DONES there will be no DEMO, so right now Granada is the center of attention. The IFMIF-DONES linear accelerator will produce high-energy neutrons with the intensity and irradiation volume necessary to test candidate materials To fully understand the role of the IFMIF-DONES project, it is necessary to briefly review the fundamentals of nuclear fusion. One of the greatest challenges faced by technicians involved in the development of nuclear fusion reactors using magnetic confinement, such as ITER, is to recreate the conditions necessary for them to operate inside the vacuum chamber of these sophisticated machines. deuterium and tritium nuclei fuse. However, this is by no means all. When this reaction takes place, the fusion of a deuterium nucleus and another tritium nucleus triggers the production of a helium nucleus and a neutron that is ejected with an energy of about 14 MeV. The problem is that the neutron lacks a net electrical charge, so it cannot be confined inside the magnetic field which, however, does manage to retain the deuterium and tritium nuclei, which have a positive electrical charge. This is the reason why when it originates as a result of the nuclear fusion reaction, this neutron is ejected towards the walls of the vacuum chamber with enormous energy. This particle is very important because in practice it will be closely linked to the production of electrical energy in nuclear fusion reactors, but, at the same time, it represents a very aggressive form of radiation that can significantly degrade the materials used in the reactor. The components that will be most affected by the direct impact of high-energy neutrons and the most intense heat flow are the internal wall of the vacuum chamber and the blanket. The components that will be most affected by the direct impact of high-energy neutrons and the most intense heat flow are the inner wall of the vacuum chamber and the blanketwhich is a mantle that covers it and whose purpose is to regenerate the tritium that must be used as fuel in the nuclear fusion reaction. This is why it is crucial to develop new materials that are able to withstand the neutron flux and therefore ensure that the reactor will have a long operational life. This is, neither more nor less, the purpose of IFMIF-DONES. And to carry it out it is necessary to set up facilities designed to allow the technicians involved in the project evaluate the properties of candidate materials to intervene not only in DEMO, but also in future commercial nuclear fusion reactors. The mission of this project invites us to intuit what the heart of IFMIF-DONES is: a source capable of producing high-energy neutrons with the intensity and volume of irradiation necessary to test the candidate materials. And this neutron source will be nothing more than a linear particle accelerator that will help IFMIF-DONES scientists to test, validate and qualify the materials that in the medium term should reach future electric energy production plants through fusion.

Chinese electric cars already have massages, karaoke and even a refrigerator. The next step is an under-seat toilet.

by

If you can’t hold back the urge to urinate while you’re in the car, the normal thing to do is wait until you make a stop at the next gas station to relieve yourself. That’s normal, and then there is Seres, the Chinese manufacturer of Aito cars, which has patented a rather peculiar solution: add a toilet integrated into the cabin that unfolds like a drawer. Exploring other areas. China has one of the most saturated electric car markets and competitive on the planet. Dozens of brands fight for the same type of audience and differentiation has become a race without limits: from massage seats and karaoke systems, even integrated refrigerators, giant screens…If everyone is doing the same thing in infotainment, why not explore the next territory? And this seems to be the conclusion reached by Seres, the Chongqing-based company that manufactures Aito brand vehicles. A portable toilet. According to they count From CarNewsChina, the Intellectual Property Administration of China granted Seres authorization for this patent on April 10. The device consists of a toilet integrated under the passenger seat that is extracted using a system of sliding rails (something similar to a drawer) manually or by voice commands. When not in use, it is completely hidden under the seat, without taking up additional space in the cabin. How it works inside. According to collect The BBC, which had access to the original document presented to the Chinese authorities, the system includes a fan and an extraction tube to evacuate odors to the outside of the vehicle. The waste is collected in a tank that must be emptied manually. In addition, it incorporates a rotating heater that evaporates urine and dries solids. Is for when the car is stopped. Before too vivid mental images arise, it is worth clarifying: the design is designed so that you stop as soon as possible and start with the task. According to CarNewsChinaSeres’ own engineers specify in the patent report that the objective is “to satisfy the needs of users during long journeys, camping or during prolonged stays in the vehicle.” Endless traffic jams, overnight stops or campsites without facilities are the intended use cases. It’s not as crazy as it seems. Toilets in cars are very rare, but it would not be the first time they have been seen in a car. In fact, just as account BBC, in the 1950s, a special version of the Rolls-Royce Silver Wraith already included a toilet under the back seat. There are also those who have modified their car to include one, such as this owner of a Toyota 4Runner. What Seres is proposing now is, in essence, a more technologically sophisticated version of an idea that already existed seventy years ago. Obstacles. Just because the patent exists does not mean that it will reach production. CarNewsChina points out several important technical obstacles, including integrating drainage pipes into compact chassis (especially in electric ones where the battery occupies a large part of the floor), guaranteeing the durability of the rails or achieving an airtight seal that prevents odor leaks. And then there’s the psychological barrier, which is basically convincing passengers that it’s perfectly normal to use the bathroom just inches from where the rest of the family sits. Seres is not going through its best moment. The company is going through a difficult time. According to data of China EV DataTracker, deliveries of Aito M9its high-end SUV, have fallen 44.2% year-on-year for three consecutive months. Seres and Huawei plan to soon launch a renewed version of the model to stop the decline. And in this context, these types of patents can help the brand, not even to make them a reality, but to try to generate conversation around its vehicles.

Anthropic is one step away from being worth as much as Samsung. And what the market is buying is not Claude

by

Anthropic, the company behind Claude, is exploring a new round of financing that would value it at more than 900,000 million dollars. If it closes, it would surpass OpenAI as the world’s most valuable AI startup. Altman’s company set its needle at 862 million last month. The figure more than doubles the 350,000 million it had in February. In just two months. Why is it important. The valuation no longer reflects Anthropic’s sales. It responds to a bet on what the company can become in five years or a decade: a provider of something resembling an essential service. Anthropic bills Claude for subscriptions and accesses to its API. That business exists, grows quickly and has reasonable margins. But it does not by itself justify a valuation that is close to that of Samsung, the Korean megalodon that manufactures everything from the chips we carry in our pockets to the ships that cross the ocean. The context. What the market is buying with Anthropic, and as often happens in the stock market, is not the present, but a hypothesis: that a very small handful of laboratories will control the foundational layer on which the software of the next decade will be built. And that Anthropic will be one of those few. And it will do so in a very profitable way. The logic, on the other hand, is the same that led to overvaluing telecos during the bubble dotcom or to the electric companies at the beginning of electrification. Whoever owns the basic infrastructure sets the rules. Google has already committed 10 billion to the previous valuation, with another 30 billion conditional on objectives. Amazon has put in 5 billion and plans to inject 20,000 more. An IPO could come before the end of the year, around October. Between the lines. That Google and Amazon, two of the largest cloud companies in the world along with Microsoft, finance a company that also sells through them says a lot about how they understand the moment. They are ensuring supply, it is not just an investment in a supplier. It is the difference between buying shares in an oil company and buying a field. Anthropic is, for these hyperscalersa deposit. Yes, but. The hypothesis has its cracks. The models are commoditizing faster than it seemed a year ago. The technical difference between Claude, ChatGPT and Gemini It is measured in nuances, not in generational leaps. If foundational AI ends up being a commodity (something like electricity or water coming out of the tap), current valuations are unsustainable. If it ends up being an infrastructure with network effects and high barriers to entry (something like an operating system), they may even fall short. The market is paying for the second hypothesis. Time will tell. The money trail. Anthropic recently announced, with restrained fanfare, Mythosa model capable of detecting and exploiting vulnerabilities in critical software. The company deemed it “too dangerous” to release and has only given it to a closed group of companies for internal testing. Even so, it has been accessed by unauthorized users. That is exactly the reason why some investors pay these figures: such a model is not sold but granted. And whoever decides to whom it is granted has regulatory power de facto that not even a Samsung, at least outside of South Korea, has ever had. The big question. What happens if the bet goes wrong? A valuation of 900 billion means that Anthropic has to generate, at some reasonable point, revenues in the order of tens of billions a year with very high margins. It is possible. But it was also important for Cisco to maintain its 2000 valuation, and it has needed 26 years to tie. The difference is that this time the buyers of the bet are the companies themselves that depend on the result. This reduces the risk of a sharp correction. And he postpones it.

Tim Cook will step down as CEO and John Ternus will be the new leader

by

Apple management is preparing for a replacement that marks a turning point in the company: Tim Cook will step down as CEO and John Ternus will be his successor. As reported by Apple, confirming the rumorsthe change is part of a pre-planned transition process supported by the board of directors. The appointment will be effective as of September 1, the date on which Ternus will assume the position after years at the head of hardware engineering. John Ternus, current Senior Vice President of Hardware Engineering, and future CEO of Apple Tim Cook will continue to lead Apple over the coming months while working directly with John Ternus on the transfer of responsibilities. Once the replacement is effective, he will assume the position of executive president of the board of directors, a role from which he will continue to be involved in the company’s strategy and its relationship with governments and regulators. The change redefines his role, but keeps him linked to the company’s strategy and certain institutional functions.

The chemical composition of galaxies has always been full of unknowns. James Webb has taken a huge step to solve it

by

The James Webb Space Telescope sees where others can’t: its infrared vision pierces clouds of cosmic dust and reaches galaxies so far away that it took billions of years for its light to reach us. Looking far into space is, in that sense, looking back in time. However, what James Webb has seen in these galaxies differs from what was expected: these early galaxies seem to have too much nitrogen, much more than expected. Among the exotic possible explanations of science, hypotheses such as gigantic stars never seen before, black holes functioning as catalysts for galactic chemistry or large quantities of stars have passed. In fact, that was the topic of conversation in the middle of a phone call while Mexican astrophysicist José Eduardo Méndez-Delgado waited in line for the doctor. On the other end of the line, his colleague Karla Arellano-Córdova, who was in Edinburgh. In that informal talk they decided to change the prism: perhaps the problem was not the galaxies, but how we measure them. The discovery. The proposal from this international team is to analyze three light signals from the same oxygen ion to calculate temperature and density at the same time, without starting from one to calculate the other (the original source of error). The result: the gas was a hundred or a thousand times denser than was assumed in those galaxies. With that correction, the galaxies turned out to be richer in metals than they appeared and the excess nitrogen was drastically reduced. Why it is important. First, because the metallicity of a galaxy is directly related to its history: the more metals there are in its composition, the more stars have been born and died within it. Until now we were underestimating this figure, which made those early galaxies appear very different from our own and suggested a sharp and discontinuous evolution. Now they look more like what we know. But the elements essential for life, such as carbon, oxygen or nitrogen, did not exist when the universe was born: they were manufactured by the stars inside and expanded when they died. Hence the interest in knowing the chemistry of galaxies: it helps to understand when the universe had the necessary ingredients for life. With the wrong measurements, we don’t know if those ingredients were there earlier and in more places than we thought. Context. The standard method to know the composition of a distant galaxy is to analyze the spectral lines of its light based on the density of the gas and its temperature. The problem is that in these primitive galaxies the gas is much denser than expected, so its application as a thermometer works poorly. And from here on, everything failed. The nitrogen anomalies appeared in the first scientific data from the James Webb Space Telescope, as this either this. Since the results did not fit the models, the scientific community threw itself into trying to find explanations. This paper proposes to take a step back: before interpreting stellar physics, check that the measurements are correct. Besides, the Webb now allows it: simultaneously detects oxygen lines in the ultraviolet and in the optical in such distant galaxies. How they do it. In essence, the trick is choosing the right signals. One of the oxygen light lines, visible in ultraviolet, has a special property: it does not distort even if the gas is very dense, something that happened with the lines they were using previously. By combining it with two other signals from the same atom, the research team can calculate temperature and density at the same time, as if they were solving two simultaneous and independent equations. Using statistical simulations, the team found that the results were consistent with other independent measurements of the same galaxies. Yes, but. As the team explains in the work, their method corrects the density error, but not other possible errors that are equally important: the gas of these galaxies also has internal temperature variations, and that can bias the results in ways that this study does not resolve. Furthermore, the method only works well when all three light signals from oxygen are clearly detected. In three of the six galaxies analyzed this was not possible, and the results are less precise. Nitrogen remains a problem. The overabundances come almost entirely from a particular ion whose emission is extraordinarily sensitive to temperature: a variation of just ten percent in that parameter would reduce the calculated nitrogen by half. No one has yet measured that temperature directly. However, it points out a path to follow before looking for “exotic” explanations: verify that the measurement tools are up to par.

the true antidote to aging is in a step

by

For decades, standard medical advice for older adults has been nearly unanimous: walkswim or do a little stationary cycling. In the end we talk about low impact activities focused on the cardiovascular system, but recent scientific evidence is giving a 180 degree turn to this recommendation, since the real enemy of aging is not only the lack of physical background, but sarcopeniawhich is the loss of muscle mass and strength. And to combat it, science points to a simple exercise. A simple exercise. Something as simple as stepping up a step, especially if done with optional extra weight, known as a weight step exercise, is not just a ’90s aerobic movement, it’s top-notch functional training. And one of the great benefits of this exercise is that it does not require having to go to a gym or have extensive equipment, but rather it can be done at home and integrated into your daily routine. Studied. It is not something that personal trainers say just for the sake of it, since there are different essays published in several top-level magazines that demonstrate that doing training sessions stepping They are tremendously effective tools. The first of them consisted of analyzing a program of only six weeks of stepping with weight at home in women over 65 years of age. The result was that they increased the power of their lower extremities by 10 to 11% and improved their stair climbing time by 9%. Another 12-week study confirmed that step aerobics Elevates overall functional fitness, muscle volume and balance. An undisputed king. Although he step It is fantastic for legs and glutes, the truth is that this should be the gateway to doing strength training with loads. This is something that made clear a systematic review of Cochrane which analyzed a meta-analysis of 121 randomized clinical trials with more than 6,700 participants. In this case, progressive resistance training, using weights 2 or 3 times a week, has a very important effect on improving muscle strength, reversing the unwanted effect of age. In this way, short sessions of just 20 to 30 minutes are enough to improve the ability to carry out complex daily activities, reduce osteoarthritis pain and increase muscle mass. More evidence. As if that were not enough, the Mayo Clinic points out that doing interval training from the age of 70, such as 6-second sprints on a stationary bike, is capable of reversing the aspects of muscle aging at the cellular level. In this way, with only 1 or 2 sessions a week for 8 weeks, participants not only reduced their blood glucose, but showed 100% adherence without serious adverse events. Of course, studies emphasize that this type of routine requires professional supervision in the beginning to avoid overtaking people or falls that are fatal at this age.

OpenAI takes a step back in the AI ​​race to completely recalibrate

by

OpenAI Sora has closed. His generative video AI that he has proudly shown on numerous occasions and which earned him a juicy $1 billion deal with Disney it no longer exists. The news fell like a bomb a few hours ago followed by the withdrawal of that billion-dollar Disney investment. Although there are those who point out that OpenAI is in trouble, those problems are not so much economic as lack of direction, and closing Sora seems only a step backwards in the long-distance race of OpenAI and AI. Go public this year and start harvesting after everything planted. In short. It’s the news of the day. Less than a year and a half after launching it, OpenAI says goodbye to Sora. In his day (February 2024, how time flies) we were amazed at what this generative AI could do. It was just 60 seconds of video and had some huge flaws, but it was one more step in the artificial intelligence race that positioned OpenAI at the forefront of the industry. Then other competing models arrived, culminating with a Seedance 2.0 that has consumed the entire Internet to plagiarize absolutely anything. Like all the others, wow. Issues. But although striking, Sora was a tool that didn’t seem to add up. While other services have integrated their generative AI models within an ecosystem or applications (the aforementioned Seedance 2.0 in suites AI or in the video editor CapCutfor example), Sora was there, away. The aforementioned contract with Disney was worth it, but it did not seem to be part of something larger, of a “creative suite” (if generative AI can be classified as such). He simply existed, and the worst thing was that others were passing him on the right. Eggs in many baskets. It was, in short, another product of an OpenAI that had eggs in many baskets. It was reaching dizzying numbers in different rounds of financing, setting up data centers, buying a lot from NVIDIA (depending a lot on NVIDIA, too) and launching products like crazy. OpenAI wanted to touch all the keys: And there are some other products, as well as a super app to integrate all that that was not being integrated into other sites. The philosophy was simple: if we are in everything, something will work, but the result has been the opposite and, as my colleague Javier Pastor said a few days ago, wanting to be the bride at the wedding and the dead man at the funeral It is having consequences. The competition tightens. While OpenAI diversified and allocated resources to touch all suits, Anthropic (which is not just a rival, it is a public enemy) was dedicated to two things. It’s not that Anthropic doesn’t have a browser or a video generator: it’s that they don’t even have an image generator. In exchange, what they do have They are functional, precise models and that they do things very well, especially in the field of amateur development with the vibe coding. Focusing on one thing and doing it very well is something that the market is seeing valueto the point that Anthropic is raising a lot of money in different recent financing rounds. In a short time, it has gone from being valued at 183,000 million to arrive up to 380,000 million, and that has had all the fuss with the United States government and the loss of contract with the Department of Defense. Money, too. And money moves everything, and while ChatGPT sweeps the consumer segment with more than 2.5 billion daily queries, you have to wonder how many paying users there are. Where the money really is, which is in business use, Anthropic controls the market with 32% compared to OpenAI’s 25%. And in programming, the distance is astronomical: 42% compared to 21%. In fact, OpenAI has seen how your business share has fallen from 50% in 2023 to just 25% today. As we say, this is where the greatest potential for growth and commercial performance is, and OpenAI is realizing that being focused on so many fields has caused them to be distracted. Or what is the same: they have covered more than they could bite off. Public company. The closure of Sora responds to a multitude of factors, but in the background there is something more important. NVIDIA has already said that the millionaire mega-rounds are overand it has done so just before the expected IPO of both OpenAI and Anthropic. When both go on the stock market, they will have to face another financing model. They will need products that generate profits to attract investors to buy shares, and right now, the one that is best positioned is Anthropic. OpenAI has a lot, but nothing makes it complete. Anthropic has less, but it is very efficient, and getting rid of Sora seems like a move to release ballast before becoming a “public” company (in the American concept). They have to focus their shooting, focus their teams (something they themselves have recognized) and stop wanting to be too much at once without having a clear strategy. Because they are becoming another example of being a pioneer It doesn’t always mean you’re the best. and that, if you don’t get your act together, competitors who have a clearer roadmap will eat your toast. Only time will tell if the strategy works, but at the rate things are going, it won’t take too long to find out.

We thought that 3D printing a gun was already disturbing. Now someone has gone one step further with a homemade guided “missile”

by

Talking about 3D printing is no longer just talking about prototypes or industrial environments. In recent years, this technology has been established as a tool available to enthusiasts and creators who can design and manufacture complex objects from home with relative ease. That accessibility has expanded the possibilities of use, but has also opened debates about its limits, especially when it intersects with weapons development. The precedents of 3D printed guns They have been on the table for some time, and now a new project once again pushes that debate into even more delicate terrain. The disturbing jump. What has now put the focus on this issue is a video of just five minutes in which the amateur Alisher Khojayev shows a prototype that is reminiscent, at least in its approach, of portable anti-aircraft missile systems. The project includes a launcher, a projectile and several electronic systems designed to assist in guidance. What does it teach. In practical terms, what Khojayev shows is a set divided into three parts that the creator presents as a coordinated system. The launcher acts as the base of the system, the projectile concentrates a good part of the 3D printed components, and an additional node with a camera can be incorporated to reinforce tracking. How the system is laid out. The architecture proposed by the project is based on linking several devices through a wireless network that coordinates the flow of data. The first step is to connect the launcher with a control computer via WiFi, which analyzes the information received and calculates the trajectory. In a second phase, the projectile becomes part of that network and receives instructions to adjust its orientation using moving surfaces. The system combines ESP32 microcontrollers with sensors such as GPS, barometer, compass and an inertial measurement unit to estimate variables such as speed and position. The cost data. The project is not only presented as a technical demonstration, but also as a low-cost exercise. According to the creator, the entire system can be assembled for about $96 from commercial components and 3D printed parts. That, of course, doesn’t mean that anyone can make something similar at home, not least because such a development would probably be illegal in many parts of the world. But it does leave a broader reading: 3D printing is reducing barriers and costs in a growing variety of projects.

BYD is already studying entering Formula 1, according to Bloomberg. And it is not a whim, it is a necessary step

by

To understand a leak you have to imagine (or be clear about) who is behind it. But also how and when the information has been leaked. And in this case, of course, there is little that is coincidental. BYD is studying its entry into Formula 1, according to Bloomberg. In the week in which Formula 1 arrives in China and the sport seeks new markets. The rumors. BYD is studying its ability to compete in Formula 1 and/or the World Endurance Championship (WEC) according to Bloomberg. The media outlet points to “people familiar with the matter,” who point out that the company calculates how much money an investment could take where no success is guaranteed. For the information of Bloomberg It seems that internal investigations would be in their early stages. And the media points out that there would be two possibilities, from creating your own team to buying one already on the grid, a more common option. Because? On BYD’s side, the reason is clear: trust. The company needs to open up to new markets but, in addition, its plans for the next five years include a rapid expansion. The company has also seen how its sales have collapsed in China and there are those who anticipate a stagnation in sales if the State does not return the purchase aid of recently recalled electric cars. Entering one or both of the competitions would give the company a layer of credibility and confidence in the face of possible new competitors. Competitions continue to be a huge laboratory where solutions and ingenuity can be developed that can then be applied on the street, but they also help create history and brand image. Chinese companies need a boost in this last sense to give credibility to their proposal. At the moment they are doing it by following all the challenges that traditional manufacturers once set themselves. That’s why Xiaomi has sought its own record at the Nürburgring. That’s why BYD boasts of having the fastest car in the world. Jumping into competition is only a natural step in strategy. Formula 1. Why would BYD be interested in Formula 1 when the championship is not going through its best moment? For several reasons: With the change in regulations, the battery and electric motors are more important than ever. Right now, the type of motorization is aligned with a proposal with which BYD can take advantage on the street. Despite criticism, it remains the queen category of motorsports. Neither the World Endurance Championship (except the 24 Hours of Le Mans), nor the World Rally Championship, nor Formula E, nor the American competitions (Indycar or Nascar) attract so many viewers to television. Formula 1 has gained enormous weight among young people in the United States. Your documentaries Drive to survive They have increased interest in a population group that may be interested in their vehicles. The country also already organizes two Grand Prix, which would serve as a showcase where, at the moment, they cannot sell their cars. Formula 1 aims to once again attract the Chinese public. This weekend F1 returns to Shanghai, which has been sowing the seed since 2004 (with the 2020-2023 break due to the Covid-19 crisis). If Formula 1 is interested in gaining followers in the country, BYD would be a great tool. And the problems? The problems for BYD are also several and almost all of them are linked to the fact that it is impossible to guarantee the return of investments in competition in terms of success. And it is difficult to measure its social impact in the short term. Bloomberg points out that a year in a championship like Formula 1 or the WEC is equivalent to investing about 500 million euros. The company does not have a previous competition structure. That leaves two possibilities: create it from scratch with inexperienced engineers or buy existing equipment. Neither option is cheap. The future of Formula 1 is uncertain. The current regulations do not convince either drivers or fans. Some teams even supported freezing the change or not giving so much weight to the batteries and others like Audi, which had already made the investment to enter it, refused. The doubt is whether the sport will maintain the current rules as they are or if they will move away from a proposal that fits with BYD’s philosophy. Just as BYD has a lot to gain in image, it can also lose it. Both Formula 1 and the WEC are dominated by Western teams, failing could mean a step back in the communication strategy. The WEC. The World Endurance Championship could be a logical and alternative option to Formula 1 that seems to have fewer risks. The organizers seem willing to open their hand with the type of motorization used, so there are not so many regulatory restrictions in that sense. This has once again attracted brands such as Ferrari, Aston Martin, Lamborghini, Ford or Genesis (Hyundai). In addition, it would allow him to grow and gain experience without having so many spotlights on him. Endurance races are an excellent opportunity to test the reliability of advances that can then be replicated to a greater or lesser extent on the street. A success would be excellent publicity and a failure would not attract as many eyes.
