More than a decade ago, Seville created a system to defend against Guadalquivir waiting for not having to use it. Last night he had to activate it

by

Anyone who was yesterday at the entrance to the Pava Charco, could see how the city’s firefighters They moved the huge gates of defense that shield the city of Seville of the floods of the Guadalquivir River. And it is likely not to know, but I was attending a historical moment: it is the first time since it was built that these steel plates (more than four of meters high and five tons of weight) have to close. Phase 1. Yesterday afternoon, the Hispanic City Council activated the emergency plan in phase 1 and brought together all emergency services (including Local Police, Civil Protection, National Police and 112) to coordinate the necessary measures. 30 people were evicted from a “chabolist settlement” that was in flood zone, control points were installed and It was decided to close The connection that connects La Vega de Triana with the city. That’s where the doors that have just closed are. He has also put the neighbors of Tablada, Valdezorras and El Gordillo on alert. But hadn’t it stopped raining? Yes, weather forecasts They do not show abundant rains In the area and in fact (although the red alert is maintained) the river flow has already begun to decrease in Córdoba. However, when we talk about Seville, the river is just one of the things to take into account. The tide. Although it is often difficult to imagine, the truth is that when the Guadalquivir arrives in Alcalá del Río (that is, 15 kilometers before reaching the municipality of the city of Seville) It is already at sea level. That makes that point more or less, the entire riverbed is subjected to the influence of the tides. And that is what worries the authorities: if the river flood coincides with the pleamar, the chances that the Guadalquivir will overflow begin to be huge. How historical is this really? Indeed, to say that the doors have closed for the first time is not saying too much: they settled in 2012 and the last time the city was on the edge of the debacle It was in 1996. However, the challenge is more than considerable. Because, like Díaz del Olmo explained years agoProfessor of Geography of the University of Seville, the reduction of the alluvial plain of the Guadalquivir (which has gone from 4 kilometers to 500 meters) adds risks to the situation. “It is worth that with the swamps that retain the water, so much alluvial plain is needed, but the current one is not much less sufficient,” he said. And not only for the plain itself, but because “If the river is wide and with meanders, the energy that the water carries is blurred; but if it is narrow and straight, the water acquires a great speed … like the flow of the river rises of the 4,000 cubic meters per second … we have a problem for which they do not serve neither the storm tanks or anything.” A monster called Guadalquivir. Luckily, we are not yet in that situation. However, this is a warning for navigators: taught by tons of concrete, rivers are sleeping monsters, but monsters after all. Just yesterday we talked about The great paradox of our time: Have to prepare for long periods of drought while we have to have infrastructure to contain torrential rains. Today we see that it is not something punctual, it is the true “new normality.” Image | Toni Pomar | ECMWF In Xataka | With the reservoirs to be overflowed with the rains of March, there is a reason for hope on the horizon: the light of the light

Segovia promised them happy as a tourist destination for balloon flights. Until he ran into the farmers

by

The most famous are those of Capadociabut Spain is also an interesting destination for lovers of hot air balloon walks. They offer them in Andalusia, Majorca, Galicia wave Valencian Communityamong other regions, although there is a province in which they have become popular is In Segovia. There they even celebrated in September A festival that brought together about twenty of pilots The walks with a view to the aqueduct and the Alcazar have found themselves with a problem: the discomfort of the farmers. And that has generated a curious pulse. Globe walks through Segovia? Yes. Segovia is a province rich in landscapes and heritage, so … why not enjoy them in bird’s view, from the air, aboard a hot air balloon? A Fast search shows that there are different options to live the experience and from the Segovia balloons festival They claim In fact, it is “one of the best destinations in the world” for activity. “That is why about 13,000 travelers choose our city every year to enjoy this experience,” they say. Is there more data? Yes. A year ago The North of Castile investigated What supposes and how much money moves aerostatic tourism in Segovia. And their results are surprising. Apart from presenting the region as “one of the ten most demanded destinations in the world” for this type of walks, the newspaper ensures that only in 2023 1,334 flights were recorded with 14,568 travelers. At an average of 190 euros per session, that translates into about 2.6 million euros. It is estimated that there is almost a dozen of companies offering their services. Why are they news? For A few weeks Segovia’s hot air balloons are monopolizing headlines in the press regional and state And curiously it is not for its success among tourists, or their turnover, or The festival planned for this summer. No. The reason is another: The fight Among the companies and professionals of the sector and another of the key guilds for the Segovian province, the farmer. As the former gained popularity, the latter claim to have encountered a problem: low -rise flights cause them “Grave damages” In the field. Why’s that? The collective denounces that when flying near the balloons they bother the cattle and it is not strange that the pilots end up posing in their plots. “They cause stamps and stress in animals. They also land without permission in private farms, fences and occupied by cows and calves, as well as in sown lands,” He denounced A few days ago Union of Peasants of Segovia-UCCL after transferring his complaints to the subdelegation of the Government. “The balloons make low -term flights through the grass areas, operating the burner when they estimate convenient. The noise caused by this device causes serious stress to the animals, giving rise to stampeds,” The entity insists. “The scared animals jump fences, wired and break into the races with obvious risks to safety and unease for the farmer. In case they were not enough, they land unpunishedly in private farms.” Are they the only ones who complain? No. The Health Defense Group (ADS) Sierra de Segovia, which brings together just over a hundred extended cattlemen of the surroundings of the Sierra de Guadarrama and the Capital Segoviana, He complained recently to North Seville of the “legal vacuum” that entrepreneurs use to land on the plots. “They would have to be much clearer things,” Add your spokesman: “It is sinvivir, this cannot be a safari, you cannot fly over the cows to enjoy passengers.” What do businessmen say? For them the situation is quite different. In An interview with The Spanish newspaper Cristian Biosca, manager of one of the companies in the sector, acknowledged “not understanding” the controversy. “There is no novelty”, argues. The only incident that consists, says, happened “a few months ago” and Biosca clarifies that it had “nothing to do” with the companies that usually operate in Segovia. Moreover, the manager argues that the complaints that receive only three “particularly problematic” farmers. “We have tried to reach agreements with them, to come to fly and see it, but nothing.” “His complaint is that we fly low and frightened cattle, but ever none of those who fly have seen that the cattle run when we pass or break fences,” guarantees bioscawho points out that the cows have already become accustomed to the balloons. “Like the right over,” he concludes. Proof that his activity is “safe” and there is no evidence of the damages denouncing the farmers is that, he states, the complaints that have been filed to date have not prospered. What is the solution? Segovia-UCL peasants union It is clear: That the flights of the balloons stop “interfering” with the cattle breeding areas. It wouldn’t even be a new exit. The group recalls that years ago, in 2018, operators and livestock already agreed thanks to the mediation of the government’s subdelegation a “flight exclusion zone” that affected certain municipalities characterized precisely by the presence of pastures. That agreement worked for a while, but UCCL denounces that the companies that manage the balloons “are returning to Campar to their width through the grass areas.” “We understand that the tourist travel activity in globe is perfectly feasible in Segovia without invading cattle breeding spaces,” insists The collective: “It is enough to resume the pact reached in its day.” And that is feasible? UCCL Defend that yes And in fact he recognizes that for several years the agreement signed in 2018 was fulfilled “to a large extent.” “It is perfectly possible, since there is more than enough airspace so that both activities can be developed without mutual interference,” concludes. Biosca remember Also that in 2018 there were areas through which the pilots “try” not to pass, but clarifies: “The balloons cannot be directed (…) is not a matter of whim where we land, the wind takes us.” Images | Victor Iniesta (Flickr) and Segovia-UCL peasants union In Xataka | A town in León wanted to force … Read more

The radar satellite at a higher height ever created

by

At 36,000 km altitude, in the geostationary orbit, China operates the “Ludi Tance 4-01” satellite. Released in August 2023is the first synthetic opening radar deployed at this point, which gives China a unique permanent observation capacity on a third of the earth’s surface. Freshly declassified. Chinese scientists have Recently revealed The design and capabilities of the Ludi satellite, which had been kept secret until now. Officially designed for weather observation, earthquake monitoring and natural disasters prevention, their details have put on alert to rival countries such as the United States. The United States Space Force rejects the Chinese narrative. Instead of a satellite for civil use, he believes that it is designed for high resolution recognition in the Asia-Pacific region: a powerful spy satellite that allows both civil applications and the collection of military intelligence. The reason for its height. Ludi is, Like the Spanish satellite Paza synthetic opening radar (SAR). But unlike peace, it is the first and unique Sar that operates in geostationary orbit. Located 36,000 km altitude, the Chinese satellite is synchronized with the terrestrial rotation to observe the same region continuously. And not optical, so it can cross the clouds and follow night objects. Ludi reaches a resolution of approximately 20 meters. While it is a lower resolution than the sub -metric of some spy satellites of the low orbit, from the geostationary orbit, Ludi can monitor around a third of the earth’s surface, specifically in the Asia-Pacific region. The technical details. The satellite was launched with its antenna initially folded. To achieve a useful resolution at so much distance, LUDI integrates numerous phase matrix emitters, which can be coordinated in unison. This “beam synthesis” technology allows multiple microwave beams to be combined in space to act as a single very powerful radar beam, which makes it possible to obtain high quality images. Only China. The launch of the Ludi in August 2023 marked the beginning of a new class of Earth’s observation platform. American scientists had pursued the idea of ​​radar surveillance from the geostationary orbit since the Cold War, but technical obstacles maintained all those plans on paper. China has succeeded. And Ludi is alone one of the Chinese satellites yaogan that operate in geostationary orbit. Image | Cast In Xataka | For the first time we have seen a photo taken by the US ultrasecreto space plane.

is able to erase the water mark from the images

by

If someone wants to protect their images to sell them or distribute them in a protected way, using water marks is usual. This protection could be useless to the new Google AI model, which has shown to eliminate those water marks in some cases. And the implications are important, of course. Generates images with Gemini 2.0 flash. The family of Gemini 2.0 flash models Google has been giving surprises in recent times. He did it certainly with his preliminary mode of reasoning, Flash Thinkingand now it does it again with its mode of image generation. In this case there are most striking options, but also one that is generating some controversy. It is available on Google AI Studio, where it is enough to select this mode in the “CREATE PROMPT” section deploying the “Model” drop -down on the right. There it is enough to choose “Gemini 2.0 Flash (Image Generation) Experimental”. Multimodal. One of the most striking characteristics of this model is its multimodal capacity. Normally to generate an image we write a text prompt to describe what we intend to achieve, but with Gemini 2.0 Flash and this new mode we can generate images through other images that we can modify (in a photo of someone with a white shirt, we could ask for for example something like “Make the shirt that is red”). Surprising but imperfect. We wanted to do a test With a starting image and then change the hair and jacket. He put his hair blonde as we asked, but in doing so he totally changed the girl’s factions. The result of the second transformation, turning the jacket into a blue shirt, was not entirely perfect, but from even that the final result is striking. Eliminating water marks. Much more surprising, but also controversial, is the ability of this model to eliminate water marks from the images. There are many Users that They shared their experiments In networks like X, and there it effectively showed how in those examples the water marks disappeared. In this example, not only did it not eliminate the water marks, but completely changed the face of the model. But it doesn’t work 100%. We wanted to try the service generating our own water brand In this image. Once generated, we ask Gemini 2.0 Flash to eliminate it, but as you can see in the image not only did not eliminate it, but also changed the face of the model and eliminated some elements, such as that small cone of pink ice cream that appears in the lower right part of the image. Here generative AI makes its own decisions, and these can be as unpredictable as erroneous. When it works it is amazing. We did more evidence, and there were cases in which the result was surprising. In this case we take An image with water brandwe cut it and try in the model. As you can see in the image headed by the article, the result is really good, but be careful: things like the bracelets of the model or the pendant disappear. Even so, the method works, and poses a problem. Back to the AI ​​and intellectual property debate. In recent days there has been much talk about how Openai asked the US government to Eliminate copyright restrictions For AI companies. In this way there would be no consequences for its indiscriminate use of works protected by copyright, and now this system adds more firewood to the fire: Google does not even consider this type of option when you designed its model, but the fact that it serves to eliminate these water marks is worrisome. Above all, for the big image banks that use them so that artists can make money with the contents they generate. What do they say in Google. From Xataka we have contacted Google, and a spokesman points out the following: “Use Google’s generative tools to incur copyright violations is a violation of our terms of service. As with all experimental launches, we are closely supervising and attentive to the comments of the developers.” In Xataka | 5,000 “tokens” of my blog are being used to train an AI.

While Andalusia and Extremadura fight against floods, the water system prepares for the next drought

by

The rains of the last days They have put end to the pertinaz drought that still affected some Spanish basins. However, water so longed for in some areas has also flooded some areas of the country, especially in the south and west of the peninsula. Flooded areas. Numerous areas of the country have dawned under the threat of floods. The rainfall associated with Borrasca Laurence has made Cut roads and evict homes Faced with the risk of floods In Andalusia and Estremadura. Part of Murcia is now under orange warning decreed by the State Meteorology Agency (Aemet). It rains a lot. A determining factor in which we have reached this situation has been the persistence of these rains. Not only has it rained much, The three successive fronts that Laurence has brought the peninsula have put pressure on the water systems of the southwest, forcing water at various points. As if this were not enough, on the Atlantic Horizon A new storm appears: Martinho. This new storm is expected to reach the Peninsula tomorrow Wednesday. Not just rain. The risk of floods has also been exacerbated by spring thaw. In this sense, Aemet has also issued Several notices yellow by thaw in areas of the central system. To what extent the situation is “normal”. We are in spring, rainfall is not something anomalous on these dates, but Aemet’s forecasts For the remainder of the month of March they are clear: the next few days are also expected wetter than usual in much of the country (except for the Cantabrian mountain range and the island communities), and especially in the southwest quadrant. End of drought? We were therefore before the end of an important drought that affected practically the entire country between 2023 and 2024. A drought that still kept some basins such as the Catalans or those of the south, despite the intense rain episodes seen in the second half of 2024. Now, we see that the reservoirs have been maintained almost constantly with filling levels above average of the last 10 years during what we have been in 2025, and this month of rainfall seems aimed at accentuating this increase (compensating A drier February than usual). Everything seems to indicate that the drought situation has been reversed. The problem is now to prepare for the next. A paradox. This leads us to a paradoxical situation and is duty Plan a drought While we disembark water to avoid risks derived from the intense rainfall we are seeing these days (and that we will continue to see during the coming ones). On the one hand, because the increase in oceanic and atmospheric temperatures facilitate the accumulation of water in the atmosphere. More loaded clouds involve an increase in the risk of intense rainfall and with it the risk of flooding. On the other hand, the drought that we live seems to be more than one of the consequences of A aridification process which affects many areas of Spain. This process implies a trend that will make the most recurring droughts.

Ahead of Alzheimer’s is vital when it comes to stopping its advance. Some of the most important clues are in language

by

Alzheimer’s is one of several disorders causing dementia in the third age. It is also the most frequent: in Spain it is estimated that in 2019 there were about 800,000 people suffer from the disease, according to data Spanish Society of Neurology. Globally Estimates They suggest that more than 30 million people live with it. One of the challenges with which patients, family and health professionals have to face is Alzheimer’s diagnosis. Of a Early diagnosis It depends a lot on our reaction capacity to face the symptoms of this disease for now incurable. We have advanced a lot in the diagnosis of this disorder. So much that one of Our main tools Diagnosis is discard, that is, rule out that cognitive deterioration detected in one person is caused by other forms of dementia, such as Parkinson’s. Fortunately, it is not the only tool at our disposal. Another diagnosis pillar are capacities. Specialists can resort to evidence that allows them Evaluate our cognitive abilities And our memory. In this context, interviews can also be conducted to the relatives who help evaluate the patient. The images by scanner, both magnetic resonances, as computerized tomographies or by positron emission, can also give clues. On the one hand they can help in the work of discarding other pathologies, but also They can help To detect the presence of amyloid plates linked to the disease. Until relatively a short time, the confirmation of Alzheimer’s diagnosis could only be done after the patient’s death, examining his brain. Conremps diagnostic techniques can already offer us a comparable degree of certainty. Partly thanks to the last of the tools available to experts, biomarkers. Collecting clues The diagnosis of this disease can only be performed by experts in the field, but sometimes it is important to be attentive to the clues They tell us that in family or relative may be developing the disease. Tracks that can notify us that the time has come to request help from health professionals. In a Recent article in The conversationSarah Curtis, a language expert at Nottingham Trent, listed some perceptible clues through Speech changes of the people who are developing this disease. The first of these indications is the appearance of pauses and doubts in speech, accompanied by a certain vagueness when expressing. That is, the person may have difficulty finding the word you want to use and just trying to overcome this obstacle by resorting to trunk words as “thing” or describing the object vaguely. Another early indication of Alzheimer’s is in confusion when using words. These confusion can be almost imperceptible at the beginning since they can start with words that allude to more general categories, such as using “animal” instead of “dog.” They are more noticeable if the substitution is for another concept in the semantic field, such as using “cat”. Another track listed by Curtis It is the passage of facts to words. People with Alzheimer may have difficulties when completing certain activities, which will result in this person talking about the activity, the emotions that arouses them or even expressing doubts or longing regarding their ability to complete the action. Memory loss can be primed with the lexical variety of the person suffering from Alzheimer’s. That is why this disease can begin by manifesting with An increasingly reduced vocabulary and a greater tendency to repeat words. The fifth and last of the indications mentioned by Curtis on his list, has to do with precision when choosing the words. A person who develops Alzheimer’s can have difficulty listing diverse words in the same category, such as different animals, food or words that begin with a specific letter. This is why the tests used in their diagnosis often ask people who perform this type of enumerations. Many people can read some of these indications and think “this happens to me too.” And it is that confusion of this type are normal. It is common for us to be tongue in countless contexts. That is why it is important to attend to changes in speech and not simply to the existence of confusion or difficulties. Alzheimer’s is a disease that does not appear out of nowhere but is gradually aggravated and is generally not detectable in its early stages. That is why it is often of vital importance attend to your first symptoms. Even more if we consider that some of the treatments are only effective delaying the disease in these early stages.

Elon Musk has revealed the formula of his team’s success. The problem is that they barely have time to sleep and eat

by

Facing The experiments and tests around the world that seek to establish a four -day workdaythe richest man on the planet proposes a hardly justifiable leap against. Elon Musk recently revealed which is the “formula of success” of the efficiency office it manages in the United States government. The keys: work So many hours that sleep deprivation threatens the health of the workers themselves. The culture of the extreme. He did it a few weeks ago through Your X account. Elon Musk revealed then that he and his department of government efficiety (Doge) work work nothing less than 120 hours per weeka figure that triples the standard day 40 hours. Musk argued that this titanic effort is what allows them to overcome their “bureaucratic opponents,” who operate with conventional schedules. What does science say to all this? Divide the day. Making the accounts more or less standard, and since a week has 168 hours, working 120 hours is to leave alone 48 hours for any other activityincluding in the eating equation, bathing, moving to work/return home and, of course, sleeping. In the best case, if an employee allocated those 48 hours only to sleep, he would get a maximum of 6.8 hours per night, well below The 8 recommended hours by health experts. However, it is still a utopia considering the time of displacement and any other of the basic needs, so it is likely that real rest is much lower. Science. In Fortune They collected several studies that warn about the serious consequences of working in excess. Mayo Clinic points out that sleep less than 7 hours At night it can contribute to obesity, diabetes, hypertension, heart disease, stroke and depression. WHO data already indicated in 2016 that 745,000 people died by cardiovascular diseases associated with working days of 55 hours or more. Microsueños. Since the 1950s, scientists Like William Dement They have documented The effects of sleep In the brain, identifying the IMPORTANCE OF REM DREAM and discovering the phenomenon of The so -called “microsueños”episodes of momentary unconsciousness that can cause fatal errors at work. More recently, studies have shown that lack of sleep reduces activity in The prefrontal cortex (responsible for decision making) and in The hippocampus (key in memory). The impact is not just neurological. The study of the World Health Organization indicated that working more than 55 hours per week increases by 35% the risk of stroke and in 17% the risk of heart disease. In terms of productivity, an investigation from Stanford University concluded that it falls dramatically After 50 hours a weekand that working 70 hours per week generates almost The same production as 56 hourswhich suggests decreasing yields beyond a certain point. Musk’s obsession. The truth is that it was already known that Musk was a recognized WORLKAHOLIC. In A 2022 interview With investor Ron Baron, he confessed to having lived three years within his factories in Tesla and Spacex, sleeping in sofastents on the roofs and even under his desk, surrounded by metallic dust and the most uncomfortable conditions. No doubt, his labor philosophy of “more hours is equal to more efficiency” has been widely criticizedsince scientific evidence suggests that imposing extreme days does not guarantee better results and, instead, It affects health and the well -being of workers. Govern without sleep. They counted in a VOX medium report that the extreme work rhythm in Doge has already generated serious mistakes In public administration. From multimillionaire mathematical failures to the accidental dissemination of classified information, fatigue seems to be affecting the capacity of the Musk team to make key decisions. The recent dismissal and Hurrying reaction of essential personnel in areas such as nuclear safety and Avian flu response It is a sign that the policy of exhaustion could be having real and dangerous consequences. Plus: Trump administration is implementing Mass dismissals in the IRS In full tax season, which could generate an administrative collapse. In short, these types of measures, promoted by an apparently exhausted team, arouse concerns about the efficacy and stability of the government Under this new hyperproductivity model. The failures of “hacking” the dream. Paradoxically, Musk and other technological leaders have recognized that The dream cannot be replaced. Companies like Eight Sleepthat sold rest capsules From no less than 4,600 dollars to Musk and his team, they reinforce the idea that, although the culture of extreme work remains promoted, they are also looking for more efficient ways to achieve that eight -hour standard. Even figures such as Mark Zuckerberg and Jeff Bezos have defended the Importance of rest In productivity. On the other sidewalk, while Musk insists on that exhausting routine, he himself has admitted that his ancient habits caused “brain pain”, in fact, his Erratic behavior in networks Social raises doubts about whether you are really improving your rest. Sleep more, no less. Despite the alleged glamor that some try to grant sleep deprivation, scientific evidence is overwhelming: The rest is indispensable For the optimal functioning of brain and body. Instead of glorifying days of 120 hours per week, the real challenge should be to find ways to maximize productivity without compromising health. One thing seems clearly clear: at the end of the day, not even the brightest and most innovative minds can escape human biology. Musk either.

A VPN is your ally to win at home security, but above all outside. This surfshark now has almost 90% discount

by

There is no exaggeration that is worth: we live on the Internet. Much of the day we spent connected, through the browser or other applications such as social networks. Internet is a very useful window, but also houses certain inherent dangers that are difficult to control. In fact, data leaks are the order of the day, such as The one that has suffered El Corte Inglés. If we want to pay in an online store or put our data on some Internet portal we are exposing ourselves to suffering attacks. This is even more delicate if we use A public wifi network Or that of a hotel, for example. The best thing we can do is use a VPN And this surfshark comes out now at a difficult price to reject: 2.19 euros a month. Surfshark Starter Subscription – Monthly * Some price may have changed from the last review Surfshark can be used on all the devices you want It is true that there are free options when looking for a VPN, But most offer a slow and limited service. The investment that Surfshark requires now is so small that it values ​​its service, since it allows us to enjoy a much safer experience on the Internet for very little per month. One of the most interesting points offered by this VPN is that it allows us use it on all the devices we want With the same account, whether computers or mobile phones. We can always take it on the mobile and, if we go on a trip, we will have it there in case we need to connect to a network of which we do not have any information. Surfshark VPN is included in its Starter Plan, which is the one that has the price at which we refer a little higher. This package, the most economical of the three you have, It also comes with another very useful tool: Alternative ID. This allows us to create a series of fictitious data in case we want to register on a website and we do not want to use our real information. This pack has a price right now 2.19 euros A month, which means that two years of the service leave for a total of 55.56 euros. It is a real discount, since without this offer the same period of time costs 439 euros. And there the thing does not end, Since surfshark also gives us three additional months.

The videos of AI have broken the Instagram and Tiktok algorithms. Welcome to the new “AI landscape”

by

A little over a month ago This unpleasant video De Instagram went viral in that social network. In him a strange creature half -spider of a man made a strange appearance in a mall. At this time the video has 3.5 million “like” and more than 23,000, but the truly worrying is not that. Collapse of the videos generated by AI. What is worrisome is that this video is part of an avalanche of videos generated by AI that is collapsing networks such as Instagram or Tiktok. And broken algorithms. As they explain in 404 averagethe algorithm of these platforms has ended up breaking through a unique brute force attack. One in which these networks do not stop receiving content generated by AI to end up saturating those recommendation algorithms. A LEA. Brute force attacks try, for example, to find out a password testing one by one all possible combinations. In this case, what they try is to saturate the algorithms so that they end up showing these videos generated by AI, and they are achieving it. Some already call Instagram Ya Tiktok “Villagers of AI” for the enormous amount of these contents, and that have made the conventional contents generated by human users have lost great relevance to the algorithm. Reality has changed. For many these networks they serve not only to entertain themselves, but to be aware of the present. Videos often try to profile reality, but that reality has now been disrupted and those Instagram or Tiktok accounts barely show anything that is real. Some videos are deep -to -detecting unappokes, and as we verify in the past, the paradoxical is that sometimes we are not even able to detect what is real and what is not. AI seeks virality and ends up finding it. The creators in social networks seek to get their videos viral, and for this they dedicate huge resources and time. In spite of this, success is not assured, but spammers that make video content generated with AI do not need to think so much: they can generate thousands of videos with very little effort, flood social networks and wait for some of those contents to be successful. The lottery of the virality is not so much if you have a lot of tickets. The influencers who are earning money with the landfills of AI. As usual in this type of phenomena, influencers have appeared with new formulas to get rich quickly and with hardly any effort. One of them, a 17 -year -old named Daniel Bittonpresumes having already won two million dollars and has a clear message. “While others invest 5 or 6 hours making a perfect video, we can generate 8 or 10 shorts in less than 30 minutes.” As? Using AI tools. The “Hot Dog” method. One of Bitton’s friends is a known spammer of Tiktok called Musa Mustafa. His method to go viral is that of the “sad hot dog”: “When you are hungry at two in the morning, even a sad hot dog knows better than any Michelin restaurant meal. Tiktok works in a similar way. Your audience does not expect (you don’t even want) perfectly polished videos.” Mustafa wonders, not without some reason, “when it was the last time you saw a viral video of Tiktok and thought: ‘Uauh, the degree of color in this video is incredible.” Or what is the same: the amount wins by a win to quality. But platforms embrace these contents. In The Guardian They already warned us Recently: social networks and networks are not stopping this type of spam, but are benefiting from it, they accept it and are even promoting it. In fact they offer tools to facilitate the generation of content through AI, which means that rather than trying to solve the problem, they are aggravating it. An example: Facebook. Meta’s firm recently launched a tool for advertisers called Advantage+. With it it is possible to create with different versions of an advertisement to try them all with the method of A/b test and then select the one that works best. For advertisers (and for the finish line, of course), all this is fantastic, because they can get more effective ads with much less investment of time and money. Are there limits? There will undoubtedly users who They reject This type of content: precisely networks such as Bluesky either Mastodon They move away from the algorithm and are more similar to how they were Twitter or Facebook years ago. But it seems clear that a vast majority of them have no problem with these contents generated by AI, which in fact have an example of success in that porn generated by the impossible combinations –A fish generated by the kissing to a woman generated by AI, an orco generated by AI marrying a girlfriend also generated by AI – they are also becoming viral. More wood for dead Internet theory. It has been talking about how the growing presence of bots on the Internet It will end that the human presence in these contents will be marginal. What we already saw with texts or images generated by the flooding Internet now we are seeing it with videos of the flooding social networks or with Virtual avatars generated by AI. The AI ​​landfill extends, and the worst thing is that not even users – which we contribute to making these contents viral – or the companies – which as we said not only do not stop them, but also promote them – seem to have a greater problem with this situation.
