China needs its own TSMC to withstand the US pressure. His best candidate already grows at a rhythm of vertigo

by

The US wants to avoid at any price that China has avant -garde photolithography equipment. These complex machines are necessary to manufacture very high integration semiconductorssuch as those used by the data centers specialized in artificial intelligence (AI). And without them the technological development of the country led by Xi Jinping has slowed down. It is fair What the US government wants. China is dedicating a huge amount of resources to the development of its own avant -garde lithography teams. Two of its largest investments They arrived in 2014 and 2019before the technological war of which we are witnessing was unleashed. In 2014, the Chinese government injected about 19,000 million dollars into its chip industry, and in 2019 this figure increased to touching 27.5 billion dollars. However, these investments pale in front of China at the end of 2023. And it is that just two years ago the government approved An investment of 41,000 million dollars expressly dedicated to manufacturers of lithography equipment. In any case, these machines are only one of the ingredients of a recipe in which the leading role is interpreted by chips manufacturers. And the best option that China has is SMIC (Semiconductor manufacturing international corp). This company has cost more than two years to refine its most advanced integration technology as necessary to produce integrated 5 nm circuitsbut your effort is already paying fruit. And is that, According to SCMPtheir income during the first semester of 2025 has increased by 22% if we compare them with the same period last year. And its benefits have grown by 35.6%. This is SMIC’s great challenge: go beyond 7 nm Dr. Kim, an expert in chips manufacturing who has worked in Samsung and currently investigating TSMC in the US, He maintains that SMIC It is about to start the production of 5 Nm chips. It is perfectly credible because, as we have just seen, we know with certainty that this company has been Working in this technology. And, in addition, Dr. Kim is a reliable source. However, this expert has pointed out something crucial that we should not overlook: the performance per wafer that SMIC has currently achieved in its 5 Nm nodes is less than 30%. When semiconductor manufacturers produce a chip wafer, some of those nuclei do not work properly. It is normal. And when they launch a new lithographic node their performance per wafer usually has a wide margin, but little by little, as engineers refine their integration processes, This parameter improves. A mature lithography can deliver to integrated circuit manufacturers a very high performance, but an incipient technology usually moves in the orbit of 50% performance, so only half of the chips produced work correctly. The 5 Nm chips that SMIC will manufacture for Huawei are possible thanks to a technology known as SAQP The problem is that for an integration technology to be profitable from an economic point of view, its performance by wafer has to be At least 70%. And, as we have just seen, Dr. Kim argues that the SMIC 5 NM node is below 30%. It is objectively a very poor performance, but we know what this low figure explains: the technique used by this manufacturer to produce these semiconductors. It is known as Multiple patterningand SMIC has used it for more than a year and a half to make 7 NM chips for Huawei and other customers. This strategy consists in transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. It works, but is responsible for wafer performance is clearly improvable. However, all probability Integrated 5 nm circuits that presumably SMIC will manufacture soon for Huawei are possible thanks to a technology known as SAQP (Self-alledhed Quadruple Patterning), which is nothing more than a Multiple patterning more aggressive and sophisticated than the one used to manufacture the soc Kirin 9000s of 7 nm and other chips. A report published by the Taiwanese media Economic Daily News ensures that SMIC will start the manufacture of 3 Nm semiconductors equipped with GAA transistors (Gate-alall-around) For Huawei in 2026. However, this is not all. This article also maintains that this last company has already completed laboratory tests that pursue the manufacture of integrated circuits using carbon nanotubes. Huawei’s plan presumably is to give this innovation to SMIC to adapt it to large -scale production.

Alcohol without drunk

by

Friday. Eight in the afternoon. You are on a terrace of the center with your friends and you want to take A couple of reeds (Maybe a couple of Copazos) to take advantage of the sun of a summer in retreat, but the only idea of the Hangover From the next morning and alcohol ruins you a good part of the weekend, so you end up asking for a ‘without’ beer. Another one. But … what if there was an IPA or a liquor ‘without’ capable of giving you the tip of euphoria and disinhibiting you, all without a single drop of alcohol, hangover or risk of ending up developing an addiction? That is the curious promise that a British laboratory has launched. What happened? That in a delicate moment for the alcohol industry, marked by the demand drop In key markets, a generational change clear in the consumption of glasses and a growing interest For the beers or wines ‘without’, there are those who already want to go several steps further and reach the ‘Holy Grail’ of the drink. Which? Neither more nor less than achieving the quadrature of the circle: liquors and alcohol -free beers but capable of drunk. Or at least give to whoever consumes them that disinhibition and euphoria point that is sought in the bottles. Who is behind? The key name in that career is that of David Nuttneuroscientist with a long experience in research and that has been exploring how drugs affect the brain, addiction or anxiety. NUTT Recognize That the drink offers certain advantages at the social level, but aspires that people can enjoy their glasses more safely and healthy, avoiding risks such as addiction, cirrhosis or aggressive behaviors. Convinced that it can be achieved, years ago he co -founded GABA LABSa firm that starts from an ambitious promise: “to provide social drinkers what they want from alcohol without alcohol.” The team works to launch a patented molecule called ALCARELLEa toilet, tasteless and colorless compound that acts as “an ingredient designed to promote socialization and relaxation.” Its purpose, They clarify From Bloomberg, it is to amplify the effects of gamma-aminobutiric acid, a neurotransmitter that transmits chemical messages to nerve cells to indicate to the brain that relaxes. The company has also proposed Another ambitious goal: That its creation exceeds traditional alcohol without being addictive. Not just that. In The interviews that Nutt grants usually speaks of some effects similar to those of the spirits without the hangover of the next day. And how are you doing? In Your website GABA LABS points out that his goal is for Alcalle and the products derived from being available in the United States from 2028, although in an interview with Bloomberg In July NUTT confessed that he hopes that the compound will be commercially available before the end of 2027. Since it was founded, almost a decade ago, Gaba Lab has been looking for molecules capable of acting in GABA receptors of the brain to achieve the desired results (and dodge the unwanted), which has led them to develop dozens of different options. “It’s about trying and refining,” recognizes the scientist. Right now the laboratory has three ‘finalist’ molecules and hopes to bet soon for the most promising to advance its research and development. Statista graph. Have you launched something already? Yes. To check Gaba’s results, we will not have to wait so long. In 2021 the company launched a drink in small quantities in the United Kingdom and later did it in the US. His name: I felt. THE BREBAJE Does not include Even the molecule that Gaba pursues, but is made with natural ingredients that aspire to offer an advance of NUTT’s plans. Its creators They present it as an alternative for customers “tired of choosing between alcohol or without alcohol that seek a functional drink that improves their social connection.” A “without ‘beer? That the last promise of the Nutt team. A few days ago the EFE agency It echoed of the launch of a ‘without’ beer capable of generating in who ingested it a disinhibition similar to that of the traditional drink. Your commercial name: Gabyr. “It provides the same effects that people seek in a drink, relaxation, sociability, but with a much lower impact than alcohol,” claims The co -founded of the laboratory from Hemel HempStad, on the outskirts of London, which is where the drink is manufactured as the agency requires. The team is also working on A whiskey and A wine. Why is it important? For several reasons. First, for what it promises. Although for now it is basically that (promises and statements of intentions), in your interviews Nutt insists that his goal is ambitious: he pursues a range of drinks ‘without’ that offers what many social drinkers in the glasses, disinhibition and a point of euphoria are looking for. Everything insists, with an alternative Not addictive neither hangover. The effects are drunk and the effects come after 20 minutes. That of course leaves some interesting questions in different fields. How to face it at the regulatory level? How would it influence driving? And how could authorities supervise their use? With alcoholic? Do you have side effects? In An interview With Bloomberg, Kenneth Sher, a professor at the University of Missouri, acknowledged that it is difficult for him to imagine a single substitute for GABA -based alcohol. Another academic, Jim Cook, also shows his suspicion in the face of possible side effects, such as drowsiness or memory loss. Is there more? Yes. After NUTT’s proposal there is more than scientific interest. The lucrative alcohol industry has experienced Important changes Throughout the last decades, and although the trend is not the same (or just as intense) In all markets, there are certain guidelines that are affecting large brands: generation Z seems less interested Because of the alcohol that their predecessors gain strength trends such as “Dry January” And much more about the beers or the wines ‘without’which already represent … Read more

Airtificial will manufacture parts of the first Spanish rocket at its Jerez plant

by

Two of the most popular names of the Spanish high -tech industry have joined their paths. Airtificial, whose factory we visited a few years ago for the presentation of The first hyperloop capsulewill manufacture from now on reusable components for the first Spanish rocket, Miura 5 of PLD Space. Jerez composite. From the dream of magnetic levitation in vacuum tubes to the much more tangible reality of access to space. Aerospace & Defense Airtificial has agreed manufacture at its headquarters A series of composite material panels for PLD Space. They are, specifically, shields for the nozzles of the new Treprel-C engines. Critical elements that serve as a structural support, channeling the thrust of the engines to avoid vibrations that deformed the nozzles, and at the same time of thermal insulation, acting as a barrier that protects the rest of the systems of the lock of the heat of combustion. Why anestificial. The new PLD Space provider has 30 years of composite experience, a more light material than the metal that will reduce the weight of the Miura 5. In the space industry, less weight means greater efficiency and more load to orbit with the same fuel. In 2018, Airtificial acquired international fame after the presentation of Quintero One, a 30 -meter capsule made in carbon fiber compound material. It was a Hyperlooptt design, one of the companies that tried to materialize high -speed transportation promoted by Elon Musk. Today Hyperloop is considered One of the great technological failures of the last decade. Although Hyperlooptt continues to try, Virgin Hyperloop One closed, forcing the Spanish Zelleros to make adjustments. Years later, Airtificial has made the leap to the space industry. Miura 5 is not a promise. PLD Space has A detailed plan to become the European rocket factoryand the pieces begin to fit. After the debut flight of Miura 1, the Miura 5 of 34 meters high and five engines in its first stage is taking shape. Although your body is made of aluminum, it uses composed materials in areas such as cofia or the covers of the engines, which will be key For your future reusable version: PLD Space will try to recover the first stage of Miura 5 after the shock, and on this depends on the resistance of the components. The company is immersed in the qualification of the new Treprel-C engines, which will burn bioqueroseno and liquid oxygen. It is the first time they develop Rocket engines with turbobombs in Spain. The confidence in the project is such that there is already a date marked in red on the calendar to see the first Miura 5. The CEO Raúl Torres It is optimistic: “December 15 of this year. That is day D”. Images | Hyperlooptt, PLD Space In Xataka | This is the Spanish rocket Miura 5: Pld Space has presented it in images and hints that version 1.2 can land

“I reduced 9,000 employees to about 5,000 because I need less”

by

In recent months, Salesforce has joined the increasingly large group of companies that are applying a restructuring of its template aimed at taking advantage of the AI ​​opportunities. In An interview In the podcast “The Logan Bartlett Show“Marc Benioff, CEO of Salesforce said that, thanks to the AI, “I managed to rebalance the number of support personnel. I reduced it from 9,000 employees to about 5,000 because I need less.” 4,000 less support employees. According to Benioff, the use of AI agents in the support department has promoted productivity and allowed the company to work more efficiently in customer and sales management. “If we were having this conversation a year ago and you called Salesforce, there would be 9,000 people with whom I would be interacting worldwide in our cloud of services,” said the director and co -founder of Salesforce. According to Benioff during his interview, the agents of AI divide the most complex tasks of attention and support in smaller and smaller ones to solve, so that these agents can carry them out Without human intervention transforming the company’s operations. The human touch. However, despite the considerable reduction of your care and support staff, the Salesforce co -founder recognizes that AI is not the solution For all problems. “These great language models can do many things, but they can’t do everything,” Benioff confirmed. For this reason, Salesforce keeps a wide team of employees in that department that attends to the most complex issues, and frees them to serve many clients who, without the help of AI, were left without attending. Benioff assured that approximately 50% of the calls received by the AI ​​agents, while the remaining 50% were Served by Salesforce employees because the AI ​​agent himself considered that human intervention was necessary. “It is not different from when you are in your Tesla in autonomous driving and suddenly says: ‘I don’t know what is happening, you take control.’ It’s practically the same,” Benioff said during his interview. New resource distribution in Salesforce. Benioff slides that the company’s restructuring has been raised as a change of weights in the organization, in which AI has resolved the great demand of personnel In the support departmentand now part of that effort can be dedicated to reinforcing the R&D and sales departments to boost the growth of the company. “There were more than 100 million potential customers to whom we have not responded in Salesforce in the last 26 years because we did not have enough staff. We simply could not return the call. But now we have a sales team that responds to each person who contacts us,” Don’t call it relocation, call it dismissal. Although in global terms, the template can be maintained at 76,453 employees that he reported In January 2025. The truth is that not all employees who previously occupied support and customer service positions have been relocated to sales and R&D departments. Therefore, although it is possible that this cut of 4,000 employees does not derive in 4,000 layoffs, it has implied a significant template cut. According The published by Bloombergin the first months of 2025 the company said goodbye to 1,000 employees in the framework of this internal restructuring, and would be replaced by an AI, as it now confirms its CEO. However, in October 2024, the same mediumpublished that Salesforce was going to hire 1,000 employees to reinforce company sales. Something that fits with the statements of his CEO in the interview with Logan Bartlett. This displacement of jobs by AI responds to the predictions that the ‘Report on the future of employment 2025‘of the World Economic Fund, which assured that AI was going to produce A displacement of employment. The report assured that, en that displacement92 million current jobs were going to be destroyed, and 170 million new jobs were going to be created, leaving a positive balance of 78 million jobs.

its owner had forgotten where he had

by

Anyone who will constantly have happened to him once he has gone to look for his car and asked: Colega, where is my car? It can happen to anyone, and my personal trick (Although there are others) is to take a picture of the square and parking floor before moving away from the car. I have the mobile full of such photos. However, in the 70s of the last century, mobiles did not exist, so it was more normal Forget where you had parked your car. This is what happened to Ion Tiriac, a Romanian athlete who participated as an ice hockey player at the 1964 Winter Olympic Games, but who later became a laureate professional tennis player winning a Roland Garros and finalist in several editions of the Davis Cup. A passionate about luxury cars, but with little memory In the same way as the millionaires They tend to buy superyatesthe great athletes They opt by the supercar. Ion TIRIAC is no exception. His collection has approximately 400 cars, all of them exposed in a museum near Bucharest, which makes Tiriac one of the most important vehicle collectors In Europe. In a recent one interviewthe millionaire collector told the story of how he forgot that he had bought a Ferrari F40 And he had left him parked in a Munich garage for a decade. ION TIRIAC, whose estimated fortune exceeds 2.2 billion dollars, according to Forbeshe was a professional athlete In full cold war. At that time, Soviet block athletes had many TRAVEL PROBLEMSso he opted for move to Montecarlo To solve it. At present it still resides in the small principality. After putting an end to his career as a professional tennis player, he began teaching the most grenade of the Monegasca society and to train other professional tennis players. There began their First contacts with luxury cars and with the collection classics. Ferrari F40 However, as the millionaire counts in the interview, for those years he worked at all hours without rest. “I had no time for anything.” That tireless work allowed him to buy the first of his eight Ferraris. Later, I know He bought a Testarrossa. At the same time, the athlete recalled that he had tried to acquire the Ferrari F40 of the then husband of Carolina de Monaco, Stéfano Casiraghi, but finally did not reach an agreement, so he achieved Ferrari F40 by another way. According to Tiriac, that car It cost him $ 700,000considering that new cost about $ 200,000. Tiriac’s problem is that he was passionate about cars, but he still didn’t have a place in which to keep Its incipient collection of supercar. That lack of space caused him to leave his Ferrari F40 parked in a garage in Munich (Germany). Ten years later, the millionaire received a call from Mr. Becker, the owner of the garage where he had parked his Ferrari F40. The German recalled Tiriac that his Deportivo was still parked in his parking lot. “I had forgotten my Ferrari for a decade,” the retired tennis player acknowledged. Realizing that he had forgotten his Ferrari for ten years, Tiriac decided Sell ​​it immediately For two reasons. The first, because it still did not have an adequate place to save it, and second because the car, after ten years of inactivity, needed to travel back to the Maranello factory so that its engine was disassembled and Restoreda necessary process after so many years without use, even for a Ferrari.

Spain has been a world reference in high speed. And the doubt is whether we are dying of success

by

Saturation. That is, according to the Government, the reason why Spanish high speed does not stop accumulating delays and breakdowns. At least, that’s what is suggested. The increase in frequencies, new competitors and the same ways. Those are, for the government, the reason why Spanish trains have been forgetting a year. 289 trains. In the 90s, “6 trains a day, by direction, today through the Torrejón de Velasco point of the Madrid-Sevilla high speed, 289 trains circulated.” With these words Óscar Puente, Minister of Transportationof those who point out that in the 90s there were no problems of delays that today exist in the high railway speed of our country. “If there was an incidence in the infrastructure or the train, the impact was minimal. The time it took another to pass allowed to solve the problem. Today when there is an incidence you have 25 trains in both ways in a radius of one hour. Therefore the effects are greater. The controversy. The bridge response tweet comes to an interpellation in which a user indicated that In the 90s you could take a train without fear of delays. The answer also coincides with a new fault in the high -speed line of the Andalusian corridor where 261 passengers had to be evicted from a train because a car caught fire Last Saturday, August 30. This caused delays throughout the afternoon. However, the fire was not the only cause of delays. That same morninga breakdown in the infrastructure was also causing delays in the trains because it was showing a false obstacle sign on the road. Although before restoring the service it was already known that this obstacle did not exist, the machinists had to stop to comply with the protocol. A summer to forget in Andalusia. The events of September 30 have been the last of this summer but, much less, the only ones. In early July, A train was stopped 13 hours On the roads and their passengers they did not receive assistance from emergency services throughout the night. Days later, another problem with A catenary in Toledo It caused significant delays in the same high -speed line. He even had to stop passing through one of the tunnels of the Malaga line by leaks in one of the facilitieswhat had caused detachments. And Adif? The first of those incidents It seemed to come from an ouigo train which was disconnected from some security systems. This caused the chain stop of four other trains that circulated in the same area. One of those operated by Renfe, overloaded by the stop, ended up suffering a small fire of his systems, being completely arrested. The problem affected More than 16,000 passengers and From Adif they pointed to the French company as the cause of the problem. Ouigo, meanwhile, returned the accusation saying that Adif did not maintain the facilities correctly. A few days later (and after the adif notice that the critical points of the infrastructure was going to review) that Second problem in La Sagra (Toledo) who stopped the trains again. More traffic volume … The truth is that the volume of traffic in the high Spanish speed has shot in recent years. To give only one example, the day of the fault that left a train for 13 hours 30 trains between Madrid and Andalusia had to circulate. Yes it is true that 30 years ago, that volume of traffic was unthinkable. To the traffic of Renfe we ​​must add the entrance of Ouigo and Iryo into the Spanish railways which, without a doubt, has stressed the tracks. If there are more trains, there are more possibilities of suffering a delay but there are also more possibilities that such delay affects a greater number of trains. To get an idea, in 1992 (with the inauguration of the first high -speed line) 1.3 million passengers traveled between Madrid and Seville. In 2024, that figure was 5 million passengers. Another 5 million passengers were recorded in the corridor to Malaga. And throughout Spain almost 40 million passengers moved in this type of trains, According to CNMC data. … but an insufficient investment. In ELECONOMIST They point out that Adif’s investment in infrastructure is greater than ever. In 2025 just over 681 million euros will be allocated while in 2015 it was 465.5 million euros. However, they point out that taking into account their heritage, Adifs spends 16% less than a decade ago. Keep in mind that in that decade, in addition, the Spanish railways have gone from some 31 million passengers To touch the 40 million and the number of trains has multiplied with the entrance of Ouigo and Iroyo. Everything indicates that the investment in the facilities is insufficient and, above all, it is late if we take into account the increase in the number of travelers. In 2021 investments were guaranteed until 2025 worth 21,000 million euros in Adif But this game It is not dedicated entirely to maintenance of the tracks. That is, it seems that “emergency” maintenance is being carried out in too stressed lines for the expense that had been made in them.

We are running out of a key material to build roads and homes. And the guilt has the war in Ukraine

by

In the middle of the month of May a photo seemed to have sneaked between the “normality” of some remote roads from Teruel. The constant coming and going of loaded trucks up to clay He had the answer to thousands of kilometers, in the epicenter of the war in Ukraine. The shortage of the material because of the conflict had found a solution in southern Europe. But now it is, perhaps, more dangerous. We are running out of TNT. From the boom to the agency. I told it a few hours ago The New York Times. For more than a century, Trinitrotoluene (TNT) was a pillar of the American military and civil industry, with millions of tons produced for The two world wars and the second half of the twentieth century. Cheap and abundant (it cost just 50 cents per pound), it became key input for projectiles, pumps and the construction of roads, infrastructure and homes. The problem? That its production generated highly toxic waste, which led to the closing of the last national plant In the eighties. Since then, Washington became dependent on foreign suppliers, mainly in China, Russia, Poland and Ukraine, which assumed the environmental costs of their manufacture. The impact of war. The Russian invasion in 2022 transformed that scheme. The United States stopped recycling explosives of obsolete arsenals, by deciding allocate your production to kyiv. At the same time, Russia and China They cut Exports to the West, leaving the American industry without access to its usual sources. Thus, the European conflict triggered a World TNT scarcity with direct consequences for arms production and, very important, also for civil sectors such as mining and construction. Effects. The lack of TNT Threat with slowing down Infrastructure projects, from roads and bridges to the supply of cement and basic materials. He underlined the Times that the usual procedure in quarries (where minimal loads of TNT detonate ammonium nitrate mixtures with other compounds) has been affected by the reduction of supplies. The use of drones, 3D scanners and digital calculations allows more precise and safe explosions, capable of moving More than 100,000 tons of rock in a single shot, but without TNT the processes lose efficacy, which raises costs and threatens the availability of raw materials. The United States response. Given the shortage, Congress approved the construction of a new TNT plant in Kentucky, with a Budget of 435 million of dollars. It is planned to start operating in 2028, but, and very important, it will only produce for military use, without supplying the civil sector. No doubt, this reflects a clear priority: ensure the autonomy of the military-industrial complex against external dependence, although leaving without immediate solution the problem of extractive and construction industries. In parallel, the pentagon works in Diversify suppliers and increase the internal production of other explosives and propellant. Alternatives and scenarios. At present, the industry seeks substitutes such as The Petn (Tetranitrate Pentaeritritol), which is already manufactured in three US facilities, although its capacity is limited and it is not clear if it can be climbed quickly. Meanwhile, the country’s army has given signs of having assured Additional TNT sources out of Poland, although Without revealing details. In any case, the situation raises a strategic dilemma: the dependence on obsolete material but irreplaceable in many processes, whose absence threatens both the war capacity and the stability of basic sectors of the economy. TNT’s scarcity exposes, one more timehow a distant war can disrupt critical supply chains and force industrial powers to rethink their energy, technological and military security.

Wetaca doubles benefits thanks to the classic digital world trick: hooking to a subscription

by

602,000 euros of net profit in 2024, twice as much as the previous year. Wetaca has achieved what seemed impossible in the competitive world of food at home: grow in sales (23%) and improve margins at the same time, according to their 2024 accounts that he collects Five days. The turn. The company, founded by former Masterchef Efrén Álvarez consistent, has ceased to be a company that sells Tápers to become one that you subscribe. The automatic subscription model, launched in 2021generate weekly orders that are sent unless the client modifies or cancels them. You no longer have to remember to ask: the menus arrive alone. This apparently subtle change has changed the business. The recurrence has become the Holy Grail of Wetaca, which has invested more than 1.1 million euros in marketing to capture subscribers, twice as much as in 2023. In perspective. The prepared food sector lives a paradox: Dark Kitchens They left their best moment behind and the aggregators of Delivery They have a complicated profitability, but Wetaca is thriving with a model that seemed to have a difficult fit with the current offer. Centralized cuisine in Villaverde. Tápers that are sent cold. Menus that last a week in the fridge. Model that asks for a conscious and planned purchase, not impulsive. The difference is in the economic equation. Without RIDERS No commissions to platforms, without the pressure of delivering in half an hour. Only efficient production and customers that automatically repeat each week. And now what. With 94 employees and a debt of 5.2 million (1.5 in the short term), Wetaca will need subscriptions to continue flowing. The commitment to new machinery seeks precisely that: producing more maintaining the margins that have cost them so much to achieve. Between bambalins. The founders Álvarez and Casal maintain 71% of the company, while Cabiedes & Partners control almost 20%. This concentrated shareholding structure has allowed them to bet on the long term instead of pursuing growth at any price, the curse of so many delivery startups. The subscription model not only allows them to sell more: that model is a prediction machine demand, optimize production and reduce waste. When you know how many tápers you will cook every week, everything becomes more efficient.

The US pursues the AGI as if it were the Holy Grail. In China they are more pragmatic and are applying AI to plant tomatoes

by

The long AI career continues its course, and although it seemed that the United States had taken the lead, China has managed to recover the lost terrain and stand up to the Big Tech. The funny thing is that The approaches of these two countries are totally differentand that makes great losers and winners here. In short and long term. US for the AGI. The North American country has a very different strategy from that of China in regards to artificial intelligence. Large technology companies are investing billions of dollars in search of that holy grail called AGI (General artificial intelligence). China, more pragmatic. On the other, China, which has adopted a different and much more pagmatic strategy. Rather pursue great objectives that a priori are far from being achieved, the Chinese government, led by Xi Jinping, is prioritizing The development of AI practical applications that are above all efficient and have limited implementation and, if it can be, low. Promises, promises. The difference between both visions is huge but highlights the mentality with which both countries face their efforts. The US companies that work in the US believe that the AGI is close despite Some experts They are clear that The generative AI is not the way. The Manhattan Project of the IA. That seems to give equal to visionary theorists looking for that AGI, because according to them, this mile military advantage that can suppose. For certain sectors politicians in the US the development of an AGI It is comparable What the Manhattan project was and the construction of the atomic bomb during World War II. But as they explain Some expertsthat project was not the three years of work, but rather supported studies and research that had been running for three decades in an US that at that time looked in the long term. China wants to be useful today. That way of contemplating the career of AI contrasts with that of China. Its leader, Xi Jinping, has not shown special interest in AGI, and its approach is much more pragmatic: he seeks to focus AI on applications for practical purposes. That has led to the Models of the AI ​​developed in China are already taking advantage of everyday tasks. Practical applications. For example, they point out In The Wall Street Journalhttps: //www.wsj.com/tech/ai/china-hasthe qualification of access exams to high school, the improvement of weather forecasts, or assistance to agriculture with methods to optimize crop rotation. It should be noted that the US also uses AI in these areas, at least in the form of projects such as Google Weather Lab either Alphafold 3 For the development of medications with AI. Chinese government support. Although there are efforts by both countries for that practical approach, the difference here is that in China there is a very fortune government support. Beijing is investing significantly in that vision with a Investment fund of 8,400 million dollars To support new startups, and both local governments and Chinese state banks have launched their own investment programs. And open models. Another of the key points that differentiate both strategies is that of the closed and owner of the models of the large US companies and Open and open source vision of Chinese models. These open models allow to be downloaded and freely modified, and also reduce the cost of implementing this technology for companies that want to adapt it to their needs. The trade war conditions everything. It is also true that commercial restrictions imposed by the US condition the Chips development and AI software in China. That has caused the Asian giant to have adopted a curious tactic: to let the US assume the enormous costs of exploring new paths to develop AI, and then follow its steps as quickly as possible but without having to face those strong economic investments. Risk aversion. Although Xi Jinping may raise a strategy that the AGI pursues, experts say it will only do it when I see that you have enough guarantees of succeeding. Kendra Schaefer, from the trivium Chinese consultant, explained How the Communist Party does not want to be threatened by an AGI that condition its future. According to her, the Chinese government is “one of the most reluctant governments to the planet’s risk.” Outstanding image | Xataka with Midjourney In Xataka | China has declared the war on private school: why he predicted the prolific “tutorials”
