Airplanes have been depending on GPS for decades. Some engineers have another idea to replace it: quantum technology

by

Airbus and the company derived from Google focused on quantum technology and IA, Sandboxaq, have completed more than 150 flight hours Testing Magnava revolutionary system that uses Quantum sensors to detect the unique magnetic “fingerprints” of each point on the earth. The initial results have been promising, and are a sign that technology could rival the Traditional GPS and even overcome it in precision. Why is it relevant. The GPS has become the Achilles heel of modern aviation. Interference attacks and Spoofing They are dramatically increasing in conflicting areas such as the Middle East, Ukraine and Russia, and this It also affects civil flights. The military use these techniques to confuse missiles and drones, but the consequences extend dangerously to commercial aviation. Hence the importance of looking for a viable alternative to GPS. Magnav. Image: Sandboxaq The secret of its operation. Magnav has more or less the size of a toaster, and has a laser that shoots photons against electrons. When the laser goes out, these electrons release the absorbed photons with a unique energy firm that reflects the intensity of the earth’s magnetic field in that exact location. An artificial intelligence algorithm processes this information and compares it with detailed magnetic maps to determine the position of the plane. Each square meter of the planet has an unrepeatable magnetic firm, created by the iron particles of the earth’s core that magnetize the minerals of the cortex. More precision and more difficult to supplant. Unlike GPS, which depends on vulnerable digital signals from satellites, quantum sensors are completely analog and process data generated entirely on board. Jack Hidary, CEO of Sandboxaq, Explain that this makes them “essentially impossible to interfere or supplant.” During the evidence, Magnav managed to meet the standards of the Federal American Aviation Administration 100% of the time, maintaining precision within 2 nautical miles. Even more impressive, it reached a 550 -meter accuracy in 64% of the occasions. Beyond aircraft. The experts They predict A quantum sensor market valued between 1,000 and 6,000 million dollars by 2040. This technology promises to detect submarines and hidden tunnels in defensive applications, and weak magnetic signs of the heart and brain in medicine, allowing non -invasive diagnoses. Joe Depa, Global Innovation Director of EY, Underline That “we are not talking about something within 20 years, but about something that is here and now.” The next step. Sandboxaq plans to go first to the defense sector before expanding to commercial flights. Although more evidence and certifications are required, Hidary stands out that have overcome “the difficult part: demonstrate that technology works.” According to him, it is the “first novel absolute navigation system that we know in the last 50 years.” Cover image | Ross Parmly In Xataka | The 777x is Boeing’s great bet to return to the top: folding wings, redesign cabin and the largest engine in the world

Its nuclear bombs return to Europe

by

Belicist machinery is a plagued scenario of symbology. We do not talk about mere ornaments, it is our own language that serves to remember, to communicate intentions or even to sow messages both on the allied side and in the enemy. From the emblems in the Uniforms to the shields painted in the fuselages, passing by badges either Levadas flags In conquered territories, each symbol can condense centuries of history or project what is to come. The latter is what has revealed A simple currency. What hidden politics. A find in Visual culture of the United States Air Force has offered the clearest signal to the date that nuclear weapons have returned to Europe, specifically to the air base of RAF Lakenheathin England, after almost two decades of absence. THE KEY: THE NAME AS Challenge coinsalso known as “round metal objects” or RMO, a very important part of the culture and tradition of military aviation. These currencies include characteristics such as the designation of unity, colors, pet, nickname, slogans and slogans, symbology and references to their history and tradition. The symbol. The piece in question is A commemorative currency 493rd Fighter Generation Squadron (FGS), a unit reactivated in 2023 and part of the 48th Fighter Wingwhich shows unambiguously a B61 nuclear bomb and an atomic fungus, visual elements that unequivocally refer to an active nuclear mission. The capture of the currency It is Tony Osborneeditor of the European Defense Section in Aviation Week. The unit in question, which together with the 494th FGS constitutes one of the First maintenance squadrons Fifth generation in Europe, directly supports combat squads of F-35athe most advanced hunting of the West Arsenal and fully compatible with the most modern version of the B61 bomb: the B61-12. Since 2021, Lakenheath is also the first wing of the US Air Force outside the United States that operates these fighters. One of the currency faces (the other on the cover) Silent return of deterrence. Although the Pentagon maintains its traditional policy of “neither confirming or denying” the presence of nuclear weapons in specific locations, multiple indications converge on pointing out that the b61 bombs already They have been deployed or they are about to arrive at Lakenheath. Among them A flight stands out of C-17A RCH4574, detected For open source intelligence sources, which started from the Kirtland nuclear base, New Mexico, after a scale in Mcchord, and landed in Lakenheath on July 18. The aircraft belongs to 62nd Airlift Wing, the only certified unit to transport nuclear weapons routinely. This journey, together with the stay of the plane in the area of the Kirtland Nuclear Weapons Center, suggests an operational transfer rather than a logistics exercise. Inert test version of a B61 in an underground vault of the Arms Storage and Safety System (WS3) at the Volkel Air Base, Netherlands Other clues. Besides, Since 2022 HE has documented The modernization of 28 of the 33 aircraft shelters in Lakenheath, equipping them with WS3 underground vaults intended for safe nuclear weapons storage. These reforms are part of the NATO Safety Investment Program (NSIP), whose 2023 budget explicitly includes the United Kingdom for facilities of “special storage”. To this are added contracts of the Department of Defense They mention The “imminent nuclear mission” of the 48th Security Forces Squadron, as well as specific training for nuclear personnel, a cultivation broth confirming that the necessary infrastructure would already be operational. Lakenheath, strategic pivot in European deterrence. The possible permanent reintroduction of nuclear weapons in Lakenheath should not be understood as an isolated gesture, but as part of A strategic readjustment in the nuclear stance of the United States in Europe. The base could serve as much as permanent storage point as backup platform For other nuclear facilities already knownsuch as Kleine Brogel (Belgium), Büchel (Germany), Aviano and Ghedi (Italy), Volkel (Netherlands) and Incirlik (Türkiye). Of all of them, Lakenheath stands out not only for his renewed infrastructure, but also for his ability to OPERATE F-35Awhich positions it as a key node for the future doctrine of tactical nuclear deterrence in Europe. Lakenheath Air Base Why UK. Here it is important to highlight that the United Kingdom, although officially does not participate in the NATO nuclear distribution program, has expressed interest In acquiring F-35a (In addition to their Current F-35b short takeoff and vertical landing) and could eventually integrate into the use of B61-12 under bilateral agreements with the United States. This would open the possibility that British fighters armed with American nuclear weapons operate from Lakenheath in coordination with the American squads already deployed. B61-12 and F-35a: New nuclear power equation. As for the new B61-12 bomb, it represents A qualitative leap within the American nuclear tactical arsenal. Endowed with a Precision guidance system Through a tail with inertial navigation and stabilization rockets, it allows nuclear attacks with much greater accuracy than its predecessors. Combined with the poaching and penetration capacity of the F-35A, it makes this duo a strategic platform with flexible response capacity, ideal for dynamic deterrent scenarios on the east flank of NATO. It is estimated that about 100 b61-12 bombs American property is currently deployed in Europe, and their redistribution, with Lakenheath as a new headquarters, could reinforce the credibility of the United States nuclear umbrella. Shared deterred vs. nuclear autonomy. It We count A few days ago. Since Trump’s arrival to power, he has grown among European allies (especially France and the United Kingdom) The concern that Washington reduces or even cancels your commitment to the NATO nuclear cast program. This fear has revived debates about the need to build a European nuclear deterrence Autonomous. In that context, the possible Return of nuclear weapons British territory acts as a counterweight and reaffirmation of the American commitment, although it does not completely close the concerns on long -term sustainability of the current model. A clear sign. Be that as it may, the symbology of A commemorative currency It may seem anecdotal, but in this case condenses … Read more

The model that dominated technology for 50 years has died

The numbers do not usually lie, especially in the long term. And Intel’s figures during the last decade speak of a historical replication. Of A giant come less in an alarming way. In figures. In 2015, Intel’s stock capitalization multiplied by Nvidia. Almost ten years later, that of Nvidia, the first company in history to exceed four billion dollars, multiplies by 41! to Intel, which has been jibarized at a time when it has been exceeded by many lower companies. A brutal change that symbolizes the change of technological era: Nvidia’s boom first for its GPUS sales for cryptocurrency mining and then for the training of AI models. Intel’s decline due to its inconsequence in the mobile era, the rival boom in CPUS, or the passage of Microsoft or Apple to ARM. And not only Nvidia has advanced. Also Texas Instruments, Qualcomm, AMD … Gelsinger’s legacy. The contrast. In 2006, Intel refused to make chips for the iPhone Because I considered that Apple was too small. That same year, Intel tried to buy Nvidia For 20,000 million dollars, but Jensen Huang refused. Today these decisions have completely checked Intel’s route, which at the beginning of the century was always in the top 10 of world companies by stock market and today is close to leaving the Top 200. The threat. The Hard recent admission of CEO Intel, Lip-Bu Tan, that Intel is no longer among the top 10 of semiconductors, says many more things. The company that fed the PC revolution, which created the Wintel ecosystem that dominated for decades and was synonymous with American innovation, now is worth less than Spotify, Coinbase or Iberdrola. Yes, but. The 5,500 new layoffs announced by Intel They are more than an adjustment or cut. In California, almost 2,000 jobs will disappear. In Oregon, almost 3,000. In total, 20% of the workforce will be fired. The workers who developed the technology that moved the world are now expendable. The turn. Intel has outsourced TSMC 30% of its production by 2025. Paradoxical in a company that presumed its vertical integration, which controlled from design to manufacturing. And that now depends on his Taiwanese rival to survive. A symbolic surrender: the king of manufacturing asking for help to who removed the throne. Between the lines. The strategy of pivoting to the edge announced by so sounds like last minute refuge. “It’s too late for us“The CEO admitted. It is not only to recognize the loss against Nvidia, it is to recognize the loss in the most important race of what we have been from the century: that of AI. And another paradox: China represents 29% of Intel’s incomemore than any other market. The most iconic American technology company depends more on China than its own market. Trump is focused on technological independence in this legislature … … but Intel needs China to stay alive. Turning point. He 18A process That must save Intel by 2025 generates certain doubts. And if he fails, Intel runs out of his last asset to compete with TSMC. If it triumphs, it will be a partial victory, since it will be arriving five years late to the battle. This Intel fall also symbolizes something else: the end of the vertical integration model in chips represented Intel against Nvidia’s specialization model. The first designs and manufactures. The second designs but leaves manufacturing in the hands of TSMC. And hence the problem for the West: advanced manufacturing is concentrated in Asia and the value is redistributed.

“He ignored the most basic standards of label”

He CEO of Twitch, Dan Clancy, He was doing stream For several hours on July 18. The reason was the noblest: participating in a solidarity marathon to raise funds for a children’s hospital. What angered the community were the forms that Clancy used to promote his streamsomething that among the community is considered disrespectful. What happened. Dan Clancy wanted the greatest number of people to see their streamso he set out to promote him. As? In the words of CLAY himself “I’m shaking blastfully into the chat of Streamers that I know to ask for Raids when they finish. “Although it is not something forbidden, it is considered a little elegant tactic. RAID. It is a way to send a lot of audience to another channel. Normally, when a streamer You will finish your live can send your audience to another person. It is a way of making known and supporting other less known creators. Ask for one RAID It is not prohibited in Twitch standards, but it is considered little elegant and even rude to do it. Spam What is prohibited is asking Raids Insistent, in that case it could be considered spam, which is just what Clancy had done. According to They tell DexertoClancy published the message in at least five different channels that added around one million followers. One of the times, a moderator expelled Clancy del Chat and blocked his account so that he could not chat for 10 minutes. Criticism. The community soon pronounced. As we said, ask RAID It is not prohibited, but it is considered rude to do it. That the CEO of the platform itself use these tactics has not sat well And some consider that it gives bad example For the community. A good cause. Although with questionable ways, Dan Clancy’s goal could not be more noble. The Twitch CEO was part of the GCX solidarity marathon which was held between July 14 and 21 to raise funds for the St. Jude Children’s Hospitalspecialized in cancer and other pediatric serious diseases. In total, they have managed to raise $ 350,000, of which $ 4,000 were collected during the stream of Clancy.

In León there are small villages that are finding a peculiar phenomenon: thousands of “ghost tourists”

by

In the world there is good and bad touristsrespectful tourists and disrespectfulclean and others capable of converting places such as Everest either The Fuji In authentic stercolera, but much less common is what some peoples of the province of León are living. His municipalities are finding a kind of “Ghost Tourism”a drip of thousands and thousands of travelers that nobody has seen or heard or housed, but that in theory they have visited the town. Or at least he assures it A study of the INE. Multiplying the census by 24. Carbajal sources It is a town of León located about 50 minutes by car from the provincial capital and surrounded by hectares and hectares of cultivation. It doesn’t usually sneak into the news, but Monday León News He dedicated him A broad article which explains a peculiarity of the people: in summer there are few municipalities in which the population shoots more for tourism. According to A study INE experimental that measures the flow of tourists from the position of mobile phones, between July and August 2024 the town received 1,826 tourists. Many do not seem like many, but it is that INE himself acknowledges that in the Leonese town there are barely registered 76 people. That is, when the heat arrives, the summers multiply by 24 the municipal census. Next to nothing. “It’s a mockery”. Such data would be compressible if Carbajal sources had a natural park, an old fortress, parties known throughout the community or some other claim that explains that avalanche of visitors, but the City Council itself itself Recognize that this figure of 1,826 tourists (464 in July and 1,180 in August) is difficult to explain … and even more difficult to assume. “It is a burial,” nods The mayor of the town, Carlos de León Saluds, in León News. Similar opinion, Ana María Ortega, former mayor and councilor, Explain That one thing is that the influx of visitors increases in July and August for the people who returns to the village or visit to their relatives and a very different one that the data is triggered in an exorbitant way. “In summer you can triple the population, but multiply by 24 the number of inhabitants with veraners and tourists cannot be.” So … what happens? To understand that mysterious “Ghost Tourism” the first thing is to go to the prine sources. The data of the 1,826 tourists leaves a new “Experimental Statistics” of the INE that resorts to the signals of the mobiles to calculate different metrics related to tourism: the place of origin of foreigners arriving in Spain, the destinations that visit the Spaniards when they leave the country and the movement between communities, provinces and municipalities. The study has been prepared for a few years and always talks about the same: “Tourists.” If we consult the “internal tourism” data and more specifically the flows of “Interprovincial tourists” Residents in Spain, classifying the results by municipalities, the surprise arrives: in July of last year Fuentes de Carbajal received 646 and in August 1,180. In total 1,826. The question is therefore … how are those figures calculated that collide the mayor and the former mayor of the people? Mobile and antennas matter? The response is given by INE in The technical file From the survey: the data is related to the position of mobile phones and are obtained thanks to the collaboration of the country’s large operators. The approach is interesting and promising, but implies certain challenges. “The location of mobile phones is estimated from mobile phone antennas”, collects the institute itself: “This implies that the location of a mobile is not established with total precision, and the error depends on the concentration of antennas.” In summary, the more mobile antennas, the greater precision. Unraveling the mystery. The INE’s ability to analyze the data is also limited. The records on mobile location are anonymous and processed each operator, so the institute receives only aggregate data and in tables, without option to examine loose values. In rural areas it is also found that the low density of the network conditions the type of ‘cells’ with which it operates. By statistical secret, the institute also hides certain data. With that information about the Ortega table Slide that the balance of carbajal sources (which is so adjusted to what is perceived in the people itself) may be due to technical issues, such as coverage or that for some reason the data of other municipalities are added to those of the Leonesa Villa, thus blurring the real photo. Near Fuentes de Carbajal there are other villas with a balance of zero visitors. In Xataka we have already addressed the INE to ask him about that apparent mismatch. Is it the only case? No. León News Informs other equally striking, although none reaches the level of carbajal sources. In San Millán de los Caballeros, for example, the INE registered 1,648 tourists in July and in August 1,602, which adds 3,250. Again they may not seem like many, but it is that the town has 191 inhabitants registered. The same occurs in Izagre, of 137 residents and who according to the statistical institute receives almost 2,000 Veranians. “We don’t have great parties, just four performances during the summer,” remember the mayor of San Millán. “There are two campsites close to the people, but they are in the municipal terms of Valencia de D Juan and Villamañán.” Nor does the Izagre councilor achieve to understand everything that happens: “On central summer days, with the holidays, between 150 and 200 people can be reached in each of the villages, but reaching the 1,987 veraneantes in those two months cannot be.” Images | Zed Mendez (UNSPLASH)Google Maps and Wikipedia Via | León News In Xataka | It is increasingly easy to see from the road a crop that had never been dominant in Spain: the pistachio

It is more profitable than Inditex

by

International expansion and diversification strategy of Amancio Ortega investor arm He is marking a milestone in the European real estate sector. So much so that the latest financial information places its real estate, Pontegadea, surpassing Inditex in profitability. The strategic turn of Ortega Empire The magnitude of the Pontegadea assets has already raised that it has already become the Real estate with greater value in Spainand has settled the foundations to become the most powerful in Europe in the coming years. Pontegadea: the new Lencio Ortega locomotive The founder of Inditex has taken less than two decades to convert his second company into A real estate empire. His modus operandi is relatively simple: use The annual dividends which provides you with 59.29% of Inditex shares, to buy office buildings, premises in strategic locations for Inditex stores, luxury residential buildings, logistics and logistics centers Even hotels. Since Inditex dividends ascend Several billions Annual, Pontegadea has dedicated the last decades to Buy strategic buildings all over the world. The key to everything is that, upon receiving every year A generous check Inditex, Pontegadea does not need to depend on bank loans to make your real estate purchases. 0% debt 100% advantages. In what we have been in 2025, the company has invested 800 million dollars in acquiring new buildings. However, unlike Investment fundsPontegadea does not base your business on obtaining profitability of the surplus value of the sale of these properties, but of becoming the landlord of companies such as Apple, AmazonSpotify and even the main competitor of your textile empire: Primark. Profitability record in 2024 According The published by The economistAmancio Ortega’s holding registered a net benefit of 9,322 million euros in the exercise of 2024. This increase represents a increase of 17.3% with respect to the previous year, placing the group at the head of Spanish patrimonial societies. According to data of Expansion, Obtained from the accounts deposited in the Mercantile Registry, Pontegadea declared consolidated income of 43,125 million euros, growing 8.7% compared to 2023. Total assets, that is, the value of the buildings owned by Pontegadea, its renewable energy business and of Inditex’s shares, exceed 110,615 million euros, which represents an annual increase of 9.3%. For its part, Inditex has also presented historical figuresalthough a little more contained than their investors expected. The company directed by Marta Ortegayoungest daughter of the founder, He scored a benefit Net of 5,866 million euros In 2024, which is 9% more than the previous year. Although the good results of both companies in 2024 were excellent, the benefit of Pontegadea was 62.9% higher than the total that Inditex obtained, which shows Cycle change and the strength of the patrimonial sector in the investment portfolio of Amancio Ortega. Next objective: Europe During the last two decades, Pontegadea has been managing the properties he was buying around the world from the local subsidiaries that the company has created in Spain, Portugal, the United Kingdom, France, France, USA or luxembourg. However, a complete redesign of its structure has just executed to centralize all assets management of Europe, Canada and the USA In his Luxembourg subsidiarywhich becomes the control center of all assets. The only exception is the assets that manage the subsidiaries of Spain, Portugal and the United Kingdom, which continue to be independent. This process aims Banke Hotel Purchases from Paris for 97 million euros and the Banco Sabadell offices building in Miami for 235 million euros more.

China built the largest high speed network in record time. Now you want something more difficult: improve it

by

China has already shown that you can do what no other country has achieved: display in record time The largest high speed network on the planet. But it is not enough to have it. The new challenge is even more complex: to improve it, make it more efficient, more connected, more useful for the economy. And that demands less colorful, but equally ambitious decisions. To grow quickly to grow well. Between 2021 and 2024, China added 10,000 Kilometers of track to your high speed network. The figure impresses, but it is no longer what defines success. The Ministry of Transportation has made it clear that the current objective is not to extend the railway map without pause, but to squeeze its potential. In fact, The country has set As a goal to reach 50,000 operating kilometers before the end of 2025. The network adds 48,000 kilometers, more than 70 % of the world total, and connects 97 % of cities with more than 500,000 inhabitants. Millions of travelers, but there is still a margin of improvement. Only in the first half of 2025, Chinese high -speed trains They transported 2,240 million people. The figure impresses, but the authorities are not formed. The objective now is to make this system more comfortable, more predictable and better coordinated with the rest of the transport ecosystem, from the urban metro to airports. High speed yes, but also logistics. China wants its high -speed trains to cease to be just a solution for travelers. The new approach includes routes adapted to the transport of goods, interconnections with airports and sea nodes, and improvements to integrate the system into the production chain. What is at stake is no longer only mobility, but the country’s competitiveness. Beyond traditional rails. While the current network is kept, China develops new generations of trains, such as magnetic levitation. These advances do not seek to replace what is built, but prepare for a future where speed, autonomy and sustainability are key. The country has already tried prototypes that reach 600 km/h In cities like Qingdao. Figures that impress. Security that holds. Moving millions every day with punctuality is an achievement. Doing it without major incidents, for years, it is even more. China has built a network that not only runs quickly, but aims to resist earthquakes, storms and overloads. According to Xinhuasince 2012 no serious accident has been registered in the high speed network. Centralized planning. Faced with chronic delays that affect many countries, China has maintained a clear strategy: centralized decisions, sustained investment and state control of the process. It is not a perfect model – there are errors, cost overruns and debatable decisions. But its results in deployment and integration are difficult to ignore. A mature network, a major challenge. As we have seen, the Asian giant continues to expand its network, especially towards interior and less connected regions. However, it is no longer just about adding cities to the map. The real challenge is another: to ensure that a gigantic infrastructure works better and better, with less margin of error and more logistics demands. The stage of the big deployments is giving way to the stage of precision.

There have always been people preparing for the Apocalypse. The difference is that they now include AI in their survival kits

by

For years there are people preparing for a nuclear war, for the end of the world, or For both. They are called ‘Preppers‘, that at times like the recent Spanish blackout They feel claimed. The movement is mutatingand as Mit Technology Review collects, the needs and possibilities of 2025 leave us people doing and proposing Collect Artificial Intelligence Language Models (AI) to save them in a USB pendrive. A good tool for the end of the world. The engineer Simon Willison, known for being the creator of the Django web development framework, has A plan For a future dystopian: keeping open artificial intelligence models, you can execute them at home if collapse civilization. In this way, even without internet access, it would be possible to continue accessing the enormous human knowledge located in its pesos. To carry out something like that, there is no need for resources beyond the reach of the homes of the homes. Today, there are already AI models that can be executed at home, Even in smartphones. Even something as powerful as Deepseek can work on our PCprovided we use a small version, the ‘distillate’ of 8,000 million parameters. As Share Evan Hahnthe Chinese Qwen 3 model, in its 600,000 parameters version, can occupy the ridiculous amount of 523 MB in our storage. With only 2 GB, we can download call 3.2 in its version of 3,000 million parameters. A powerful but “economical” team like a Mac Mini M4 can run models capable at home. An alternative to something more traditional: all Wikipedia. Download all the wikipedia To read it without connection, it is something possible with different options, and something equally useful in an apocalyptic scenario such as the proposal. Hahn has included what he would occupy with the great open language models, and using little space, enough information can be stored. With 356.9 MB we can access the 50,000 best articles in Wikipedia. And with 57.18 GB, which fit perfectly in a modern pendrive, we can have in our possession all the Wikipedia available in any language. Occupy less than half of the space, we can have QWEN 3 of 32,000 million parameters and Deepseek R1 of the same size. Limitations. Using artificial intelligence at home to have access to the knowledge of the world sounds very good, until not so much. Simon Willison himself told Mit Technology Review to use the local AI models “is like having a strange, condensed and defective version of Wikipedia.” The reason is simple: the models are trained with data available on the Internet, to the point that the AI bots are putting the future of Wikipedia at riskHowever, these models do not faithfully reproduce all the information when we enter Prompts o Indications to ask about a specific topic. The hallucinations problem. Not only are they confirmed by actors such as OpenAi, but for them we know that models such as O3 and O4-mini They hallucinate more than their predecessors. According to Jensen Huang, we need much more powerful hardware So that this phenomenon of AI disappears, and of course, it is not hardware that we have at home. In addition, small models executable at home, being very small versions in size and memory used, toThey look more. And more limitations. In our tests executing local AI models on smartphones, The results are irregularalthough promising. In that sense, Apple itself will open in iOS 26 his AI to any developerso that they can execute it on the device itself. Beyond the quality of small and local models against the gigantic Grok 4, O3-PRO either Claude 4 a ‘prepper’ plan with pendrive has more limitations, and is to trust such a unit for a situation that requires, above all, reliability. These USB units are not designed to last more than 10 years. If they have poor quality NAND chips, they can even stop working without use. And that is why there are companies like Machdyne UG, which has created a pendrive that It lasts 200 yearsor so they promise. Of course, even if I achieve that longevity, it has an 8 kB capacity, which only gives to save some text. If you want to store almost all the knowledge of humanity, it is best to think of a lasting environment in optimal conditions. And then, think about major disasters.
