You can no longer sell your chip for the most successful in China

by

The commitment reached Jensen Huang, the general director of Nvidia, and Donald Trump At the end of last week In the restaurant of the Mar-A-Lago Tourist Complex of Palm Beach (Florida) It was a mirage. Wet paper During the last weeks several filters anticipated that the Department of Commerce, which under Trump’s mandate is being led by Howard Lutnick, intended to prevent the chip for artificial intelligence (AI) NVIDIA H20 I continue to arrive in China. At the current situation for the company directed by Jensen Huang this GPU is very important. In fact, her engineers designed her to have a chip for the people who could deliver to her Chinese clients when US sanctions They prohibited Nvidia for sale in the country led by Xi Jinping of the GPU A800 and H800as well as graphics cards with chip GeForce RTX 4090. Previously the Department of Commerce had also radically restricted the sale in China of the GPUs A100 and H100the most advanced of Nvidia at that time. Nvidia’s success in China has the days counted The reception they have given to the GPU H20 The Chinese clients of Nvidia has been very good despite the fact that the capabilities of this chip are clearly lower than those of the other proposals for the this company. In fact, initially the Department of Commerce allowed its sale in China because this integrated circuit met the restrictions it had imposed. And despite its limitations its sales in China 50% quarter to quarter have grown Since he arrived in this market in mid -2024. The US Department of Commerce has imposed export restrictions on China from the GPU H20 Despite all this era of bonanza for Nvidia in China is about to finish. And finally the leaks have been fulfilled: the US Department of Commerce It has imposed restrictions to the export to China of the H20 GPU, and this in practice means that this chip presumably It will not reach Chinese clients in Nvidia. During the dinner I have mentioned in the first lines of this article Jensen Huang presumably committed to Donald Trump to invest more money in data centers for the US. In return, Nvidia could continue selling its H20 GPU in China. After all, this is the chip that currently supports its business in this Asian country. But This pact has faded. And the company led by Jensen Huang is already paying it. His shares have fallen 6% and Nvidia has announced that this prohibition will cause a hole in its accounts of 5.5 billion dollars due to the commitments linked to the H20 GPU that the reserves of this chip had already acquired that it will finally not be satisfied. Among the Chinese clients who have bought large amounts of this GPU, and who presumably planned to continue doing it, are Tencent, Alibaba or Bytedance.

China responds to the US with 125%tariffs. It no longer makes sense to upload them more

by

The US has been significantly increasing tariffs on Chinese imports: rose from 20% to 54% April 2, then to 104% the April 8 and finally at 145% April 8. China has been responding. Rose from 10% to 34% April 4, then at 84% On April 9 and now he has just announced a last response, uploading the tariffs to US imports to 125%. And now what? China counterattacks. On Friday the Chinese Ministry of Economy advertisement The new tariffs with a striking message: at this point they already give equal future ups of tariffs by the US. “In view of the fact that there is no possibility of acceptance in the market for US goods exported to China with the current tariff level, China will not pay attention if the US part continues to impose tariffs on Chinese merchandise exported to the US in the future.” “A joke”. According to indicate In The Wall Street Journal, “although USA continued imposing higher tariffsit would not make sense from the economic point of view and would become a joke in the history of the world economy. “Indeed, with those tariff levels to producers no longer compensates for trying to sell their products in countries with these tariff levels. It makes no sense to upload them more. Zhiwei Zhang, president of the consultant Pinpoint Asset Management, indicated In CNBC that “this is the end of climbing in terms of bilateral tariff fees. Both China and the US have sent clear messages, and makes sense to upload tariffs beyond.” Talks? It does not seem that there is intention to initiate negotiations between the two countries, something that can cause colossal disruption in world supply chains. Even so, a spokesman for the Chinese Ministry of Commerce indicated In an additional statement that Beijing is open to negotiate with the United States on equal terms. The primary sector in danger. China exports more than it matters, but there is a sector that can be very punished by these tariffs, and that is the primary sector of American farmers and ranchers. That same segment is the one that has given many votes to Donald Trump in the elections. Soybean, a worrying example. The soybean industry is According to The New York Times one of the great affectedBecause China is the most important market for soybeans exported by the US. According to the US International Trade Commissionthe segment of “grain, seeds and fruits” represents an exports of $ 13,350 million, 11% of total exports to China. Above is just oil.

Nintendo Switch 2 is no longer a toy, it is the closest to the final hybrid console

by

Nintendo has presented the Switch 2a console that respects the original concept, but that is far from what it offered us The first generation. Nintendo has never cared that switch was a toy that moved games in 720p resolution: I knew I was going to sell the same. But 2025 is not a year to launch a poor power console, and photography has changed completely. Switch 2 is no longer a console whose specifications can be ridiculed. It is a laptop with desktop soul. But a real desktop. A heart of Nvidia. The original Nintendo Switch had a processor Tegra of Nvidiathe same as Nvidia Shield. This generation repeat processor manufacturer and, although they have not transcended technical details about it, it once again has a tegra. One capable of moving graphics of up to 1080 120 fps in the console, and 4k 60 fps in desktop mode. In other words, the switch finally has a decent resolution to compete with the best. First level consoles such as X and PS5 series support 120 fps but, being realistic, the catalog that supports this refreshment rate is minimal. 4k 60p is the standard, and switch finally meets it. A level catalog. ‘Star Wars: Outlaws’, ‘Cyberpunk’ or ‘The Duskblood’ are just some examples of a new era for switch. One in which the console that once was a toy can move triple. PS5 and Xbox One X. (It will be especially interesting to compare it with One S), but there is undoubtedly a key here: it is finally time to compare the switch with a desktop console. To this we must add both the retrocompatibility with Switch 1 games and the emulation capabilities to which Gamecube is now added. Triple A price, for games and console. 90 euros. It is the price that Mario Kart World ‘will have for Nintendo Switch 2. The rest of the games can wait for the 80 euros, 20 euros more than the classics 59.99 euros that we could buy games for the first generation. With a price of 469.99 euros without games, Switch competes directly in the league of the most top of the market. The key? Nintendo does not go directly for that market, he has his own, and now he has more arguments than ever to convince. For almost all. Buying Switch 1 was to launch a clear message: Import Nintendo, not the graphic quality. Nintendo Switch 2 ends completely with this, now becoming the hybrid par excellence to play some triple A deliveries (the initial catalog is and aims to remain reduced), but also to what Nintendo does remain Nintendo: its own titles. To play this type of deliveries in portable console the price is high: rivals as The Rog Ally X are going to 799 euros. More powerful, yes. Without switch versatility, too. Only time will determine the success of this new switch. What is clear is that Nintendo has understood that hardware and performance matter and, finally, we have that switch we deserved.

Your future is no longer in communications

by

Telefónica is about to complete a historical transformation that completely changes the nature of your business, as published by Expansion After the first public intervention of his new CEO, Emilio Gayo, in the great Catalunya Expansion meeting. The current situation. 43% of Telefónica’s business income in its four main markets (Spain, Germany, the United Kingdom and Brazil) already comes from services that are not communications. Why is it important. This silent transformation shows how the one that was a simple telephone operator is leaving its traditional business behind to become a diversified technological company. Telefónica is close to that turning point where more than half of its business billing will come from technological services, not voice or data. Right where I wanted to be. In detail. The IT technology segment is growing “in double digit” according to Gayo, while the traditional telecommunications business has already exceeded its peak of investment in infrastructure such as fiber and 5g. The investment ratio on income (capex) will go from 12.9% in 2024 to no more than 12.5% ​​in 2025. This reduction does not mean less investment, but greater efficiency and adjustment to real needs. The general panoramic. Telefónica seeks to redefine itself as a “tractor company” at European level, betting on two parallel strategies: Consolidation in key markets (Spain, Germany and the United Kingdom) where “will study any option that is raised.” Accelerated growth in non -traditional technological businesses grouped in Telefónica Tech. The contrast. While in Europe the operator is committed to growing and consolidating, in Latin America (Chile, Ecuador, Mexico, Uruguay and Venezuela) will continue releasing ballast ballast that does not stop causing losses and erode their margins. Only Brazil is a big business for Telefónica in the American continent. The transformation began in 2019 and the results are already visible. In Spain he has closed 2024 “with figures that we did not see since 2018” (precisely a merit of Gayo before his new promotion), growing in all parameters. In the United Kingdom, he has generated “the expected synergies 18 months before the committed.” And now what. The question is whether Telefónica will complete this metamorphosis without losing positioning in your traditional business. Gayo has pointed out that Movistar Plus remains “a key lever” for the residential segment, letting read between lines that will not completely abandon its roots while reinvesting. The success of this strategy could mark the way to other European operators trapped between American technological giants and Asian manufacturers.

The question is no longer whether the rains return or not. The question is what is happening this spring with the meteorology of Spain

by

“Have you enjoyed the sun?” The meteorologist Roberto Granda asked Yesterday at noon. “Well, hurry, because from Tuesday afternoon the clouds and rain return to much of the country,” he continued and, effectively, it will be like that. In fact, from Wednesday to Friday, we will see enough rain in the west of the peninsula. But, of course, the key issue is no longer If the rain comes back or not. We have that clear. The key is what is happening this spring to meet all this rain. But, first of all, why don’t it rain now? Basically because during these last days an anticyclone has managed to close the hall of deep storms that had emerged in the Atlantic. However, it is not one of those anticyclones that remain on our heads until weed. While I write this, the anticyclone is already giving way for cold air masses to get into the country from the southwest. But that It will end. From Tuesday (and, above all, Wednesday) it will rain a lot in the Guadalquivir, Guadiana and Tajo basins. In fact, According to the weather index that measures the rarity of phenomenathe rains could be remarkably intense in the southern zone of the central system. Again. But the thing does not end there: another blockade. As Víctor González explainsboth the European and the American models have begun to draw an anticyclonic block in northern Europe in their departures. That is, a structure very similar to the one that has accompanied us in March. However, it is still early to know what will happen (because there are several options). The blockade in northern Europe Direct the storms Towards our latitudes. However, we need not an anticyclone about our heads. If in the end a dorsal is assembled on the peninsula, we will notice a “tempered and slightly unstable atmosphere”; But if the blockade is broken in the south, we can return to a situation very similar to last month. Is April a new March? Not so fast. That is alone one of the possibilities that arise. It is not clear that it will happen (And, much less, with that intensity). However, what we are seeing is already interesting in itself: in a country so prone to persistent stability, this uncertainty is really very striking. Hence, this article cannot end with the question we always ask ourselves “What can we expect?” We are entering An atmospheric dynamic that, beyond the rains this week, We can expect anything.

The Max Airpods have become the example of Apple’s contradictions. Consistency is no longer a priority

by

Apple has just announced that Airpods Max with USB-C port They will receive a software update in April that will allow them to reproduce audio without loss (Lossless) and ultra-low latency. The trap: this characteristic, highly anticipated from The arrival of Lossless A Apple Music in 2021will only work when they are connected with cable. That is, wireless headphones of 579 euros (originally costing 629) will need to be physically tied to a device to offer the highest sound quality. One part is technically understandable, but the other part is paradoxical. Irony. The Max Airpods were born promising “high fidelity sound” In 2020, but when Apple launched the audio without loss in Apple Music just five months later, these premium headphones were able to reproduce it. Not even by cable, because the decision to introduce lightning instead of USB-C or a 3.5 mm jack prevented it. Four years and a port change later, finally this capacity comes, but with a giant asterisk that changes the nature of the product: you must give up wireless freedom, precisely the main characteristic for which customers are willing to pay that price. Between the lines. This movement says a lot about the current Apple. The company that was once characterized by its obsession with details and coherence is now allowed to fragment in divisions with disconnected priorities. The USB-C port allows a completely digital transfer, eliminating the technical problem of lightning. But this solution, although technically correct, is late and fragmented. Why not include this capacity from the release of the USB-C version? Why announce it now, months later? Apple has even created its own wireless protocol for loss without loss With the pro. Why not expand it to iPhone and Mac? The answer has more to do with product calendars and allocation of resources than with purely technological limitations. The background. Apple’s decisions about high quality audio reflect a commercial strategy rather than an absolute commitment to excellence. Audio without loss in Apple Music was mainly a competitive response to rival services, not a crusade for audio quality. If it were the second, it would have planned from the beginning a real solution for its premium devices, instead of adding patches over the years. Meanwhile, ecosystem fragmentation grows: The AirPods Pro 2 They offer lossless audio, but only with Vision Pro. The Max Airpods will now, but only with cable and only the USB-C version. The consistency of the experience, the “It Just Works“That defined Apple for years, fades. Perhaps it is a consequence of the Growth of its catalog, which has gone from minimalism to calculated maximalism. Sometimes, perhaps, inconsistent maximalism. And now what. Apple is subtly repositioning the Max Airpods with this ad. In his press release They highlight “significant improvements for composers, producers and mixers”, with focus on Workflows of Logic Pro. This new approach to audio professionals lets us intuit a strategic change: The Premium consumer segment has not responded as expected. They need to differentiate themselves from competitors that offer similar characteristics at a lower price. They look for a niche where the high price is more justifiable. The big question. Is this fragmentation simply the inevitable cost of the growth of the company and the catalog, or does it reflect a deeper problem? The Apple of Steve Jobs made fewer products but each told a clear story and occupied a specific place in a perfectly integrated ecosystem. The Apple of Tim Cook has multiplied its catalog of products and services, but at the expense of a certain coherence. The result: users who need to investigate what generation of which product is compatible with what functionality –The iPad and Apple Pencil is the icing-. A scenario that contradicts the promise of simplicity that defined Apple. Turning point. Apple is increasingly adopting a philosophy of “good enough now, better after.” The products are launched with incomplete characteristics that are then added by updates. This approach can work well for software, but it is frustrating when it affects premium hardware that users do not usually replace. For current Airpods Max owners with USB-C, this update is a late but welcome improvement. For those who have the Lightning version (for sale until seven months ago) is another reminder that Apple can leave relatively recent products behind without too many objections. And for potential buyers, it is a signal to wait for a future version with better wireless capabilities. The ironic thing is that, after eliminating the 3.5mm jack from the iPhone, arguing that the future was wireless, Apple now reminds us that for the best audio quality we need … return to the cables. Specifically to one of forty -five euros. The circle closes, but not precisely in the most elegant way. In Xataka | Apple Intelligence is a “fire” for Apple.

We believed that creatine was one of the most useful supplements to gain muscle mass. We are no longer so sure

by

Creatine is an old acquaintance of people who exercise in order to increase muscle. Evaluate in our own meat the effectiveness of a supplement is useless, especially because we surely accompany it with a strict exercise regime that will prevent us from distinguishing its net impact. That is why, if we ask ourselves to what extent the creatine works, we need to study it rigorously. Not so effective. And the verdict of the last study that has tested this substance It has not been favorable. In a study that included a 12 -week training program and the consumption of 5 grams daily of creatine supplement were not observed relevant differences between those who took the substance and those who did not. “We have shown that taking five grams of creatine supplement per day does not make any difference in the amount of muscle mass that people earn when performing resistance training,” explained in a press release Mandy Hagstrom, co -author of the study. “The benefits of creatine could have been overestimated in the past due to methodological problems,” the researcher adds Creatine. Creatine, or α-methyl guanido-acetic acidit is a compound that can be found naturally in our body, especially in the muscles and cells of our nervous system; And also in some foods, such as red meat, fish and shellfish. Creatine molecules are formed from three amino acids and Stores phosphocreatinemainly in the muscles. There is used as a source of energy. That is why the creatine supplement is used to obtain better results when exercising and gaining muscle mass. 54 participants. The recommended maintenance dose of this supplement is between three and five grams per day. The 54 study participants, aged between 18 and 50, were divided into two groups, some would begin to take five grams Creatine Monohydrate (CRM) first and a week later they would start a 12 -week resistance program. The second group would also face this exercise program, but without the supplement. The food of both groups was monitored to verify that there were no relevant differences in their diet. Both groups increased their muscle mass, but they did it in a similar way, about two kilos won during the period. The details of the study were Published in an article In the magazine Nutrients. The problem is in the water. Part of the study key is in time: that the experimental group (the one who took the supplement) began this “treatment” before training allowed the team to test (and verify) a hypothesis, that a part of the muscle increase that we associate with creatine is due to a greater water retention. The team observed that, during this first week, indeed, the group (and especially women in this) began to gain muscle mass, a 0.5 kg difference that dissipated after starting training. Hagstrom pointed out, of course, that more studies are still necessary to understand the impact of water retention associated with the consumption of this supplement. Dose question? The study responsible for the study suggests that, in addition to water retention, the chosen dose could also have had effect on the results. The five grams daily represent the upper limit of the recommended daily maintenance dose, but those who consume This supplement They often resort to a “load phase” that implies consumption between 20 and 25 grams of the supplement per day. This possibility was discarded by the equipment since these consumption levels, they explain, can cause gastrointestinal problems and is not necessary to achieve saturation levels. However, they affect the need to carry out additional studies with intermediate doses, for example of 10 grams. They also point out that longer -term studies could help us better understand the impact of creatine supplements on the increase in muscle mass.

Organilleros are part of the cultural fabric of Mexico City. The problem is that there is no longer the one to manufacture the instruments

by

The music is The language of the soul, and a universal language. The streets of large and small cities in half the world have musicians of all kinds that make a living, do so by hobby or to entertain in an act that would shudder to the SGAE. In Mexico, that street music is tradition, one that remains alive thanks to the organilleros. They have a couple of centuries behind them and the saddest thing is that they are the perfect example of natural obsolescence: organillos will not die because there is no one who wants to touch them, but because there will be no one who knows how to repair them. The organ. The figure of the organillero may be far away right now to those who live in Europe. It is possible to see them at popular festivals in some German municipalities, but it is somewhat more anecdotal and reserved for concrete moments than anything else. In Mexico, the thing changes: there are still listening daily in cities such as Mexico City. Also in Buenos Aires or Santiago de Chile. The cylinders The curious thing is that the organilleros were born in Europe, such as Organillos. It is a portable mechanical instrument that was invented in the 18th century, but that was perfected when it arrived in Germany during the nineteenth century. The box can be decorated with the reasons you want It is a mechanical instrument with cylinders that have protuberances or perforations that rotate through a crank and activate a series of tabs. In doing so, an internal flame expels air through tubes, which are those that produce musical notes at predefined height and rhythm due to the cylinder itself. You don’t have to know music, go, you just have to turn the crank. Crossing the puddle. In Germany they were tremendously popular, but also in Italy, France, the Netherlands or Spain. Each country could adapt them to their popular songs and the organilleros went through the streets and squares entertaining the room of the pedestrians. It was a way to popularize music and, at some point at the end of the 19th century, they arrived in Mexico. It was a bombing. Ganoa. ‘Wagner and Levien’ was a musical instrument house founded by German immigrants who not only brought the organs, but also rented them to those who wanted to make a living playing on the street. They continued to be manufactured in Germany, so it was necessary to import them and it is said that the most important in this regard was Gilberto Lázaro Gaona. HE esteem that there were 250 organillos that acquired in the 1930s, coinciding with the moment in which they stopped manufactured in Germany. And they are the ones that, modified to reproduce Mexican popular music, have been circling through the streets of the city. Tradition. These organs weigh their own. Some get to overcome the 50 kilos and, although there are models that can be carried in tow, the most common is to support them on a stick or on a wheel support that facilitates transportation. The organilleros are wearing their traditional uniform and are dedicated to … that, to turn to the lever to activate the mechanism and color some of the transitted streets in the city. Obviously, thanks to the sensitivity with the animals, now it does not happen, but before these organilleros could carry a monkey that collected the donations and completed the show. Also in Chile Controversial and counterpoling. They are, therefore, part of the cultural fabric of Mexico City and, as happens so many times, there are tourists who do not see those local traditions with good eyes. Famous was the case of an American tourist who complained through social networks because of the sound of this instrument. They soon Fall criticism that did not harass the young woman, defenders of the trade of the organilleros, of the cultural importance they have and, why not say it, of that zeal for the homeland that sometimes exalts when we feel attacked. In extinction. Now, the organilleros seem to be far from disappearing, but another song is what will happen with the organ. Due to the use, possible accidents and friction between the elements, these organs are wearing and must be repaired. Do you remember the 250 pieces that Gaona imported? Well, it is estimated that the rest were lost, they were stolen or sold to collectors, and those 16 are those that continue to rent to the organilleros. And the person responsible for that business and its repair is, as we read in Unknown MexicoMarcela Silvia Hernández Cortés, Gilberto daughter -in -law. Her husband was the one who had the business and she taught her because the two men told her to dedicate himself to the kitchen when she tried to learn the trade. Legacy. After the death of her husband, Marcela learned on her own to repair these organs that, if they have survived, is thanks to her expertise and dedication. The sad thing is that there is no school of organizers, nor new pieces, because the factories closed and the hope of the artisan, as he commented on the news, is that their granddaughters continue with the legacy. “It is very laborious, but sometimes I look good,” Marcela said in the news, who also comments that, beyond the tradition, the organizing trade is an opportunity for people of a certain age who have run out of work and that they cannot, for whatever reason, access one. The artisan is a precious profession and, as we saw with the popular response to the video of the American tourist, the role of the organillero is respected and appreciated by the Mexicans. So much that there is Organizations that work to conserve this tradition.

The Chinese no longer marry

by

China wants more babies. That is clear. Which generates doubts in a society In transformationin which young people marry less and less, divorces grow and birth It has been In free fall it is how to get it. Over the last years the Xi Jinping government has tested solutions of all kinds, since Finance painless births either Grant aid to proclaim the benefits of marriage in classrooms or even call directly Women to encourage them to have children. Now it is proposed to try A new trick: Reduce the legal age to marry. There are those He already warns That will serve as little. AGE QUESTION. When there for the 70s China raised how to stop his overpopulation not only designed his famous “Politics of the only child”the rule that for decades (until 2015) prohibited the country’s couples from having more than one rod. Another of the measures promoted by the government was to limit marriages placing the legal age to marry in 22 years for men and 20 for women. The result, like I remembered a few days ago Global Timesdaily backed by the Chinese State, is that the country now has one of the most restrictive norms in the world. By prohibiting boys under 22 and young women with less than 20 can go through the Chinese altar became one of the nations with the legal age to contract the highest marriage in the world, moving away from the 18 years that mark the common threshold at international level. In the EU for example the Minimum age To marry is 18 years old in Scotland, where young people can give the ‘yes I want’ from 16. Most laws foresee marriages before age, but only with permission from parents or a judicial body. What if we change the norm? That is the idea that the professor of Econometry Chen Songxi He has transferred to the National Committee of China’s Political Advisory Conference (CCPPCH), An important political advisory body of the country. Chen’s is not just any voice. First because he is a member of the Chinese Academy of Sciences. Second because it is part of CCPPCH itself, which meets these days precisely to consider proposals in different areas, from economic and social to technological. In that prestigious (and influential) forum one of the issues that generates the most in China will be touched: the loss of population that the country drags Since 2022 And its consequences both social level As economical. Precisely for this reason Chen transferred some proposals to CCPPCH: completely eliminate birth restrictions (since 2021 they are allowed Only three children as a couple), apply a system of incentives to marriage and birth rate and review the age at which Chinese young people can marry. Objective: greater birth. In The chronicle of Global Times It is clarified that Chen’s goal is very clear: encourage birth. With the proposal, The newspaper requires Chinese, you want to “expand the fertile population base and release the reproductive potential.” It is not Beijing’s first movement in that direction. Throughout the last months (and years) the government has opted for tax advantagesimprove access to treatments either campaigns which highlights the advantages of motherhood and life as a couple. And that between a long etcetera of questionable success initiatives. In 2024 China saw how its birth rate increased (registered 9.54 million births compared to 9.02 of 2023), but even that rebound leaves a bittersweet flavor. First because the data of 2023 had been lousy, marking the minimum since 1949. Second because even that slight rise prevented the country from closing the year with a bad demographic balance, losing 1.39 million inhabitants and chaining its third year of population fall. Will the new measure work? One thing is that the CCPPCH endorses Chen’s proposal and the government decides to cut the legal age for Casere, placing it in 18 years, and another very different that this movement will really encourage Chinese birth. There are experts who are already quite skeptical. “It will do nothing to increase the fertility rate now that people have accustomed to marry and have children later,” Explain to Financial Times The demographer Yi Fuxian. Is not the only one that thinks so. The data of course invite you even though the measure will have a small effect. In 2020 the average age of the first marriage in China stood quite above the 20 years that mark the legal minimum for them and 22 of them: among women it was from 28 years and among men of 29.4. Can the fact that couples go through the altar will make this measure reduce? And yet, do you have to translate that into greater birth? South Korea neighbor leaves an interesting example: despite the fact that there the legal age to marry It is already 18 years oldPeople continue to decide to go through the altar much later. The trend It approaches In fact at 30 years. Who thinks of weddings? That is the second weak point of Chen’s idea. Experts may see in the marriage a way to improve the reduction of the country, but the truth is that the Chinese themselves think less and less about marriage. The 2024 data Disseminated by the Ministry of Civil Affairs itself, they are of course revealing. Last year they gave the ‘yes I want’ in China 6.1 million couples. Not only represents 20.5% less than in 2023. The data confirms the downward trend since 2013, but also marks a new historical minimum in official statistics, which date back to 1986. Beyond demography. Cen’s proposal has not awakened too much enthusiasm in networks. Largely because it is not entirely new. As the Chinese birth rate descended the idea of ​​lowering the legal age to marry has been giving a hole in the public debate with moments when gaining greater prominence. It happened already in 2019. And then in 2021. The South China Morning Post collected these days Comments from Weibo users who are skeptical: … Read more

I have tried Grok 3 and it is really intelligent and fast. The problem is that this is no longer enough

by

I’ve spent a few hours trying Grok 3the new version of Xai AI. I wanted to see their real abilities and especially how it behaves, what kind of results, in front of Chatgpt, Claude, Le chat, Deepseek… Reasoning and problem solving It stands out in mathematical problems. I made him complete the challenge Aime’24of which he was 6 of the 15 problems, for the 9 hits of OPENAI O3-mini-high. In addition, Grok 3 took a little less than five minutes, but O3-mini-High took almost six. Very striking to see their self -assessments until you find the correct answer (although sometimes it was not). A fragment of the steps that Grok 3 took to evaluate their own conclusions before presenting them as a final result. Image: Xataka with Grok 3. In basic reasoning tests, such as determining the number of repeated letters in somewhat complex words (the classic “lollapalooza”) or comparing decimals (9.11 vs 9.9), Grok 3 responds correctly after a few seconds of visible “thought”. O3-mini-High Be right after 6 seconds. Image: Xataka with chatgpt. Grok 3 also succeeded, but after more than four times longer. Image: Xataka with Grok 3. In a Greek mythology question about Jason’s maternal great-grandfather, Grok 3 found the correct answer in 18 seconds … while O3-mini-High needed 22 seconds to fail. Well played, Grok. O3-mini-High missed. Image: Xataka with chatgpt. Grok 3 instead gave a better built response, in addition to correct. And it takes less. Image: Xataka with Grok 3. Search and synthesis Its function Deepsearch is fast but sometimes it is not entirely precise and does not mention any important detail. I asked to analyze the impact of AI on chips design and, although it generated a text of 1,504 words with several quotes in just over a minute, omitted to mention important advances such as the framework ALPHACHIP from Google. In later and insistent attempts he did. I also asked for a full report on Xataka On financial, media, reputational level, etc. It was quite successful, although it showed an inherent limitation of any Deep Research system: He knows a lot about what is in public, but he doesn’t have many Insightsit lacks the expert criteria that knows not only the public, but what underlies. This is something of Grok and any other with Deep Research. When you ask for information about something you do not control, it is easy to assume that Deep Research (or in this case, Deepsearch) gives you everything. When you are in garlic it is easy to detect deficiencies. As in this example. Image: Xataka with Grok 3. The speed impresses: it is remarkably faster than Deep Research of OpenAi … but at the cost of sacrificing depth for speed. Of course, your selection of sources and appointments is usually really good. Unlike Gemini, it does not allow exporting reports directly to documents or customize the research approach. Again: Grok is very intelligent and capable, in his own way, but he lacks a product. Little llm is of little use if it forces to start from scratch and process all the information. Creativity and tone To try his creative writing I asked him for a story about a time traveler facing a paradox. The result was quite solid in construction of characters, details, descriptions and atmosphere, overcoming even the one that I consider the best in that aspect, Claude 3.5 Sonnet. Of course, some plot turns seem quite forced. Image: Xataka with Grok 3. His humor is basic and predictable, limited almost all the time to quite obvious words games. Teenage humor If the concept of disturbing valley You can move to a chatbot, Grok 3 is in that 99%: too fine to look like a caid robot, too predictable to finish convincing. It maintains political neutrality even on issues such as immigration or trans rights. Musk says it can be politically incorrectbut it seems that it is something that has more to do with what the user requires that a feature of his personality. That is to say: it can be taken out of correction, but only when the user pushes to it. Some limitations It does not allow customizing the behavior of the model, unlike chatgpt; or the response style, as Claude allows. It is limited to being a text drawer. You are only accompanied by the buttons to attach a file, activate your Deepsearch or activate your reasoning mode. That, and a few elementary instructions. No projects such as Claude or GPTS of Chatgpt, or the agents of Le Chat. In short: Nothing to retain pre -established contexts and guidelines or documentation to facilitate work. We always have to start from a new canvas. The interface is good, intuitive, simple … but they miss tools that make it more versatile and appetizing to integrate it into our day to day. It is powerful and capable for specific uses, but the product built around chatgpt, claude or le chat (projects, agents, previous instructions, etc.) make those alternatives something much more interesting for serious and recurring use. Image: Xataka with Grok 3. The security keeps are stricter than those of Grok 2. with that version We hallucinate for its lack of scruplesbut Grok 3 seems to recover them: he refused to generate a template for a mass fraud campaign by mail simulating that I am a Valencian prince in search of heiress. The generation of images does seem, again, more lax. Midjourney does not allow to create anything containing the words “Donald Trump” or “President of the United States”. Nothing. Grok 3 does not put so many objections. Not even with its owner. Image: Xataka with Grok 3. You can try Grok 3 from its official website or from Its integration into x (which is why you have seen two somewhat different interfaces in this article). It is temporarily free, but we already know that it will be one of the reasons to pay a subscription to X, and not the cheap. Its ability … Read more
