Duolingo was the fun, brave company we loved that taught us languages. Today it is sinking in the stock market

Most people never manage to turn their ideas into business successes. Luis von Ahn (Guatemala City, 1978) has achieved it twice. The first, when he created reCAPTCHA and sold it to Google in 2009 for a small fortune. The second, years later, started from a much simpler concept. Learning languages ​​was a painso von Ahn wanted to turn that into just the opposite: something fun. This is how it was born Duolingoa company that taught how to speak languages ​​with a strong component of gamification. You already had to go to an academy or spend long periods of time in online courses: you could learn words, phrases and pronunciation through small tests when you were on the bus or waiting in a queue. Duolingo achieved the most difficult thing: making us like each other (and fall in love) Learning with Duolingo was fun and comforting. The small rewards worked and turned it almost into a video game that little by little more people became fond of. The snowball got bigger and bigger and Duolingo became one of those companies that already seemed likeable at first. It seemed that everything it did was done well, and little by little the company took important steps to become the giant it is today. The certifications arrived who wanted to rival the famous TOEFL exams, their platform for schools, and more and more languages. Some, like japanesewere a challenge. Others, like the Klingon or the high valyriumwere above all a diversion that consolidated the fun and cool image of the company. Then things started to get interesting because Duolingo wanted to not only teach us languages ​​to speak, but also programming languages. He was encouraged to want to serve as a tool so that the little ones They learned to read and write. And for the young and not so young, Duolingo wanted to become private mathematics teacherof music or even chess. All of this ensured that over the years Duolingo managed to solidify that company image that Not only did he solve real problems, but he did it in a friendly, friendly and fun way.. In 2021 the company decided go public and after a couple of relatively calm years, the shares began to rise in value significantly. Everything seemed to be going great for the company. And then everything went wrong. AI has mortally wounded Duolingo, but not because of what we think When OpenAI presented GPT-4o in June 2024, many of us saw the future. One in which you no longer typed on your computer or on your mobile screen: it was enough to talk to him. That promised to transform many segments and kill some others, and among those threatened were companies like Duolingo. At the time it wasn’t so obvious, but when we saw that kid solving a math problem With the help of AI, it was not difficult to imagine that education, as we had known it, could have an expiration date. Curiously, that didn’t seem to affect Duolingo too much. The company continued to grow, but then two things happened. First and foremost, a major blunder. Luis von Ahn advertisement in April an “AI First” vision in which I would bet on artificial intelligence as a new great tool for your growth. The message sounded like “let’s do without the human being,” and although von Ahn tried to clarify things, the damage was done. After that, the debacle. Duolingo shares began to plummet. But the thing didn’t end there. The second of those turning point events occurred in August, when GPT-5 demonstrated that one could build a custom Duolingo for, for example, learn french in a fun way. People stopped being in love with Duolingo and they began to criticize her precisely because of what had made her succeed. There was too much gamification and, as i said a user on Reddit, “for me the reward for learning a language is learning the language.” Source: Cinco Días. Stocks continued to fall almost steadily. These days Duolingo presented financial results, and the curious thing is that although they were good, they were not good enough for Wall Street. The firm reached 135 million active monthly users (50 million use it daily), 20% more than in the same period of the previous year. It also rose 34% in paying users. Although one would think those numbers were fantastic, they also warned that the forecasts for the fourth quarter were not so optimistic. Result: new stock market debacle. So much so that the shares have plummeted 64% since reaching their highs on May 1, just after the “AI First” announcement. Since then, Duolingo’s drift has been worrying, and the coming months will undoubtedly mark its future even more. The company is in a difficult moment, and the rise of AI may end up causing those experimenting with their chatbot to realize that starting to learn languages ​​​​is as easy as telling ChatGPT “I want to practice my English with you a little. Correct me when I say something else and suggest small exercises” out loud. That is the great challenge for Duolingo going forward.

AI has just taught us the future of the most important application of our life: subscription browsers

How much of what you do on the computer do it in the browser? Exact. A lot. We don’t think too much about it, but The browser is the application by antonomasia of our time. Not so much on the mobile, where native apps – which are often browsers disguised as something else – triumph, but of course in desktop and laptops. The Internet has been the indirect guilty of this transformation of the browser in one of the pillars of our life. The greats of technology know it well, and for more than three decades they have tried to conquer with their browsers to dominate the world. Of that mythical Netscape We become absolutely dominated by Microsoft Internet Explorerand after the occasional scarce with Firefox —Now in really low hours– We end up yielding to a Wonderful and disturbing Google Chrome. This company, by the way, was clear from the beginning how important the browser was. So much that they created an operating system absolutely focused on that idea: they called it Chrome Os. During all this time, yes, there was something inherent to all those browsers: They were free. Microsoft, Apple, Mozilla, Opera and of course Google gave them to us. They did not need to charge for them because they earned (and earned) a lot of money indirectly with their integration of search engines, especially Google’s. They tell Apple: Google pays about 20,000 million a year so that your search engine is the native in Safari. If you pay so much, imagine what you earn through the searches made by users of the iPhone, iPad or Mac. Thus, using the browser has always been something we have done without thinking that it could cost us money. That will change very soon. Hello, subscription browser And it will change because before us a new era opens in which browsers want to be much more than that. And to achieve this they have allied with AI models that allow interaction with websites to be much more powerful. The promise of browsers with AI It is exceptional. One of the first, Perplexity Cometit autocalifies as “the browser that thinks with you.” Like him, browsers with AI are able to summarize that article that you are reading or answer questions about it, integrate conversational engines and little by little they are beginning to integrate something especially promising: AI agents What do things for us. That click alone and fill for forms and that they even overcome captchas without help. But do that this time will not be free. Not at least if we want to use those options intensively. This is what The Browser Company is already raising, the company that first developed Arc and? He abandoned it To launch your own browser with the call day. Josh Miller, CEO of The Browser Companyhe confessed in An interview With The New York Times that in the coming weeks will launch subscription plans that will go from five dollars a month to hundreds of dollars a month, depending on how much users want to take advantage of the NA of the browser. There will still be a free version that will allow a limited use (probably very) of these options, but the future of this browser is not to be a browser, but to be a subscription browser. The decision made by this company is totally logical: Using AI is not cheap, and using it is still less cheapso if you want to do it, you will have to pay. It is the same as we are seeing with the different models: Chatgpt, Gemini or Claude can be used for free, but if you want to use them intensively and access their most advanced options, it is time to pay by pointing to their subscription plans, as is the case with Chatgpt Plus, Google Ai Pro or Claude Pro respectively. Browsers are already the most widespread way to interact with AI, so it is logical to think that all of them – Hello, Firefox? – will end up integrating these functions. He has done it day, he has done it, he just did it Edge with your co -pilot mode And it is expected that Integration between Gemini and Chrome So it is much more direct. All of them will remain free in their basic versions. We can normally navigate as we have always done, but if we want to go further, if we want to use all those attractive AI options, Touch to pay a subscription. One that will be increasingly expensive. We will have to go to the idea. In Xataka | Anthropic has seen that their users do not stop using the 200 euros plan a month of their AI. They had to stop their feet

The US has taught the tariff rope with Brazil again. Embraer has a lot to lose, and its customers too

If you live in Europe, fly in a Embraer is not the most common. But the truth is that these Brazilian planes are more present than they seem. In airports such as London City, Where only a few models can operate, these jets dominate the track. Even in Spain his footprint was remarkable: Air Europa had several E195 in its regional fleet until the beginning of 2023. Embraer is not a minor actor. It is one of the world’s largest manufacturer in the world and its e-hes-especially the E175– They hold a good part of regional traffic in the US. Airlines such as American, Skywest and other regional United Express operators have clearly opted for them. With Boeing in low hoursEmbraer is emerging as an emerging candidate for the select group of the great manufacturers. A tariff triggers uncertainty President Donald Trump has threatened to apply A 50 % tariff To Brazilian products as of August 1, an unprecedented offensive in relations between the two countries. In parallel, Brazil already mentions a mirror answercovered by a recent reciprocity law. Although there is still no confirmation about which sectors they would be exempt. With a large part of Embraer’s orders aimed at the US market – where almost 95 % of firm orders from E175 come from airlines such as American, Skywest and other United Express operators -, the new measure threatens to significantly increase their products significantly. Not only will the final prices of the jets be affected, but the cost of the Imported components from the United Statesessential for manufacturing, it could also be affected if Brazil decides to apply, in retaliation, an equivalent rate. Among those components are enginesCF34 manufactured by General Electricthe airplane system Honeywell Primus Epicas well as landing trains and actuators supplied, mostly, by Collins Aerospace (USA) and Liebherr (Europe). An essential part of each aircraft that, if more expensive, would also impact the production costs of the aircraft destined for other markets. This dual effect could have broad spectrum consequences. On the one hand, airlines could be forced to Reconsider your purchase strategies If the price jump translates into higher operational costs. On the other, if the manufacturing cost is increased, Embraer’s global competitiveness would be compromised, even in regions where its position is solid. As Flightglobal collectsEmbraer has indicated that he is evaluating the impact of this measure on its operations and has been active in the dialogue with the authorities to try to restore the exemption of the import tax that has historically favored the Brazilian aeronautical industry. However, queen uncertainty. This tariff is part of a Trump communications series to leaders of more than twenty countries, with warnings that rates can modify “according to the relationship.” The lack of regulatory clarity leaves manufacturers such as Embraer – and suppliers, airlines and passengers— In a difficult situation to anticipate.

We have been trying to recover the concentration for years using white noise. These researchers believe that we are self -taught

In 1984, the German director Philip Gröning He wrote to the prior of the Great Cartuja requesting permission to record a film about the isolated and lonely life of the Cartujos monks in the heart of the French Alps. That is, about the great silence. The monks told him they had to think about it and thought about it for 16 years. He left everything recorded in ‘Into the great silence‘And every time I cross the movie I think about the same thing: that this deep and dense silence is an endangered species. In the modern world We can only use noise cancellation And, if perhaps, put on white, pink or brown noise. Or we believed. But is it really for something? That is what Joel T. Nigg and his colleagues from Oregon Health & Science University have wondered. In A recent article They have systematized everything that is known so far and, although there is good news, their conclusions are a jug of cold water. To start because, although it is an issue that is spoken a lot, there is no quality research that is based. NIGG’s team He just found 13 Useful studies (with 335 participants in total). The sample was limited, but enough to explore how the different types of noise affect the attention and cognitive function in young children and adults. And what have they discovered? Indeed, as we thought“White and pink noise improve performance in tasks that require attention for those who have ADHD symptoms.” For going to the data, they found “a small but significant positive effect (improvement of between 8 % and 10 %) in the executive care” of these people. In addition, the results are surprisingly consistent. In fact, it seems, those who were not medicated, obtained better results. What is the problem, then? That the effect is reverse in the case of people who did not have ADHD. “In this case, white and pink noise negatively affected the performance in the task,” Emily Reynolds explained. A notice to navigators. Because on the one hand, it is a good sign that, often, the information we obtain online, from mouth and even the theoretically reliable sources. The evidence available in these fields is usually much more anecdotal than we would like to confess. However, we should not exaggerate the conclusions of this work. After all, as the authors themselves saidthe investigation is scarce and not as good as we would need. That allows us to draw some conclusions, discard some things; But do not unbrush all the pitch. So … we must stop putting white noise? At least we should rethink it if what we want is to concentrate. It can be used for other things and, who knows, there may be cases that are better than the alternative (listening to music, having the background TV …); But in general terms, it seems that it would be necessary to rethink it a bit.

There was a time when poop moved the economy of half the world. His name was Guano and taught Peru a valuable lesson

Throughout history, humanity has interested in different resources. Maybe the Gold fever It is the best example to see how the obsession with a specific one unleashes the madness in those who seek to make it its main source of income, arramping with everything they find without thinking that it can be bread for today, and hunger for tomorrow. With the case of gold it is logical, but … Did you know that something very similar happened with excrements of sea birds? This is the story of the guano, the ‘white gold’ that transformed the Peruvian economy for both better and bad. White gold. Friedrich Wilhelm Heinrich Alexander von Humboldt was a man with a lot of free time. Born in 1769, this German was a philosopher, scientist, geographer, naturalist and explorer, among other things. During a trip through South America in 1802, Humboldt He visited the Peruvian coast and was interested in how the premises used a white element as substratum For crops. His name was Guano, and it was the result of the dry excrements of sea birds. HE says That, walking through an area where there was a lot of stored guano, he began to sneeze out of control, and it was his curiosity that encouraged him to send samples to Europe to study his components. What happened next is not something that caught us by surprise at this point: pre -Columbian civilizations were generations using the substrate, Europeans found that the guano was a magnificent fertilizer and began to be interested in him. Pass. The guano is literally fertilizer. His own name “Wánu” in Quechua means “fertilizer”, and really had a unique composition to enrich soils. This guano was a wonderful result of the conditions of the area. The mixture between the dry climate of the Peruvian and Chilean Islands, the composition of the rocks on which they fell and the excrement fruit of the marine diet of the birds resulted in a compound Rich in nitrogen, phosphorus, calcium and potassium. It was ideal for improving the health of plants and promoting their growth, so European and American farmers began to pay close attention to the substrate. The reason? The increase in the population was causing an overexploitation of the fields, which led to its exhaustion and a series of unsuccessful crops. You had to find a miraculous solution, and the guano had all the ballots to be that solution. Peanut mine. The two territories began to exploit the resource based on good. Between 1840 and 1880, the demand for the guano exploded and the Peruvian islands became a very precious good. The United States and the ‘Old Continent’ carried dozens of ships with this white gold and Peru came nothing wrong. In those 40 years, Peru exploded about 11 million tons of guano, with estimated revenues of about 38 million dollars. That decontextualized amount may not tell us too much, but the guano’s income allowed the country to develop with ports, railways and roads. Not surprisingly, the first year of exploitation of the guano, the appeal contributed 5% of the income to the country. Facing the last decade of Bonanza, that input It was 80%. A real barbarity. The “Guano War”. It was so popular that the United States, to anyone’s surprise, believe The Guano Law of 1856, for which any American citizen could claim uninhabited islands that had guano deposits. This led to the private appropriation of a hundred of islands in the Pacific and the Caribbean, but the thing became serious between 1879 and 1884. It was when the “Guano War”, A conflict between Peru, Chile and Bolivia for the control of the richest deposits of both Guano and Salitre. As a result, Chile attached some very important enclaves, such as the Atacama desert (which today is one of its wonders for the production of renewable energy), and things for Peru began to change course. Interestingly, the nations that entered that war had been allied against Spain, where guano control was also an important point in the Hispanic-Sudamerican War. To produce, beautiful And crisis. Peru focused so much on the export of the guano that, when the fever sent at the end of the 19th century, the country entered In an economic crisis. It is not that the world stopped wanting Guano, since it was still a very precious resource, but there were two reasons that led the main buyers of the substrate to look the other way. The first was that the reserves began to exhaust and the rate of production could no longer be maintained. The second was that synthetic fertilizers began to appear that could be more or less efficient, but above all they were cheaper because they did not have to bring them through dangerous crossings of thousands of kilometers by boat. The lesson in the Peruvian economy was that they could not focus on a single resource and its economy could not depend From something like that, which highlighted the need to diversify to avoid similar situations in the future. Present. Now, the Guano is still an excellent fertilizer and not only produces the Pacific Sea Birds. The bat guano also has fantastic properties such as fertilizer (in addition to being easier to obtain). And the resulting of the excrement of seals and penguins is also highly valued, but also a very expensive resource because the populations are diminishing. In the end, the Guano played an important role not only in the economy of the countries involved, but at the beginning of the modernization of agriculture, by stimulating investment in fertilizers and, when they began to scarce, to the development of artificial fertilizers. The cycle is repeated. On the other hand, it was One more example How from the Old Continent exploited the resources of Latin America, using local labor under conditions of almost slavery for the benefit of the stranger. And, writing these lines, it is impossible not to draw parallelism with the Rare earth At … Read more
