With O3 and O4-mini, chatgpt reason better than ever. But more important than the model is that we can ask you certain questions

I read Alberto Romero a few days ago in his great The Algorithmic Bridge counting Three stories who shared something disturbing: they were Three people saved by doing something as simple as asking chatgpt About his symptoms. They did not use Prompts sophisticated or advanced techniques. They only described pain, discomfort, a concern. And they lived to tell. The interesting thing in the conductive thread of these three stories is not that the AI ​​was right (although he did). Is that Natalia came up with asking Chatgpt for that tension in his jaw. It is that Cooper thought about sharing his dog’s analytics. And that Flavio, with an increasing pain, will value consulting a Chatbot In addition to a doctor. The protagonist of these three stories It is not chatgpt, but that previous momentthat moment that someone thinks “What if …?” We live obsessed with what the machines are taking us away. Employment, singularity, creativity. But along the way we are losing something almost equally valuable by our own foot: The ability to imagine unplanned uses, unlikely connectionsways of use that break the instruction manual. The gap is not only between those who dominate technology and those who are not between those who can reimagine it and those who use it following established patterns. Is Like when we buy a new oven. There are those who feel patiently to read the instruction manual memorizing each official function, and those who immediately begin to tighten buttons, turn dials and create combinations that perhaps or the manufacturer conceived. Both will end up cooking, but it is the seconds who will discover that putting the grill A medium power while turning the fan, an impossible finish is achieved to achieve the official recipes. True innovation has always emerged from those who consciously ignore theoretical limitations. The good thing is that, in the same way as Talent is very democratic, This capacity does not understand credentials. A programmer senior You can get stuck by writing code with Chatgpt while a teenager discovers that asking him to simulate difficult conversations before having them. And it turns out that it works as an emotional mirror that never appeared in any manual. The stories that Alberto collects have something more in common: they occur in the medical field, where knowledge has historically been power. Where the diagnosis flows from top to bottom. Where the informative hierarchy is so rigid that it has its own uniform. However, there are Nature, Cooper and Flavio, investing the order, leading to the expert a diagnosis that they could not have formulated but that the AI ​​could detect. It is not a matter of blind faith in technology (Everyone confirmed with professionals). It is something much more subversive: a silent rearrangement of who has access to what information and at what time. While we keep wondering if the machines are going to steal our imagination, the reality is much simpler: The decisive is not what AI takes us away, but what we think about doing with it. There is the true competitive advantage of the 21st century: in that ability to see possibilities where others only see tools with predefined instructions. Natallia, Cooper and Flavio did not save their lives for having access to superior technology, but for daring to think differently. In Xataka | O4-mini is much more than another model of AI.

China has organized a half marathon in which 21 robots participated. We have questions

Last Saturday a popular half marathon was held in Beijing in which there were some unique participants: 21 robots joined thousands of human runners to try to complete the 21,097 meters of the urban tour. The event has allowed to yield some conclusions about the Robotics art statusbut it has also generated new questions. Varied robots. In the race They participated Humanoid robots of Chinese manufacturers such as Droidvp or Noetix Robotix. The designs and sizes varied significantly, and were from 1.2 m high models to others that measure 1.8 meters. One of them remarkably imitated the human appearance in a robot that even waded his eyes or smiled. You by your side, I for mine. Although the organizers brought breast, stating that it was the first race in which humans and robots ran at the same time, in reality the Robots route was separated from that of human corridors. The robots were also accompanied by teams of engineers who monitored that their operation was correct (or that the batteries changed during the race). Slow. At the moment the performance of biped robots in the race was modest, and everyone ran clearly more slowly than human corridors. The fastest robot It was the Tiangong Ultra of the Ubtech company in collaboration with the Beijing Humanoid Robots Innovation Center. The tour ended at 2:40 hours after exchanging his batteries three times and falling on one occasion. Only six of the robots ended up crossing the finish line, and most did not last long in the test. Still far from humans. He was the only one that ended before the time limit was fulfilled to finish the test for human runners, which was 3:10 hours. The world record is in 56 minutes and 42 seconds, while a good time for human amateur runners is 1:45 hours for men and 2 hours for approximately women. Varied disasters. As they point out In Wiredthe Tiangong Ultra and the second classified, the N2 of Noetix Robotics at least managed to end at a slow but consistent rhythm. Others were a disaster. It happened with a robot named Huanhuan that moved at snail speed while moving his head uncontrollably. Another call Shennong had to be disqualified (he used small wheels) but the serious thing was that he turned on himself after starting the race and He fell next to their human operators. In some cases the operators used adhesive tape to protect the “feet” of the robots, but also to hit the head of one of them when it fell during the race. Critable autonomy. In addition, the robots were accompanied as we said of human operators. Some had control panels to go to the robots, and others went ahead to point out the way and remove obstacles from Enmedio. During the broadcast several spectators commented how operators seemed exhausted with all that operation to help robots to advance. But running is not theirs. The truth is that these robots are not designed to run, but the objective of the companies that design them is to be able to execute a variety of tasks that have nothing to do with moving quickly. Even so experts indicate that this test demonstrates the evolution of the market, because a few years ago It was difficult until they were walking. Even Elon Musk launched a job offer to “teach Tesla’s Robot Optimus to walk”. That some can already run a half marathon It is a good proof that some companies have created especially robust models. Important absences. Chinese manufacturers participated in the race, but many were absent reference companies In the market. Was not for example the Optimus of Tesla, but neither does the Atlas from Boston Dynamics, the Figure O2 of figure ai or the Apollo of Apptronik. There were also absences of large Chinese robotics companies Like Unitree (which did not officially participate, although two were used by other institutions), AGIBOTor the runner robot Star1 Robot was. Is this for something? The test organized by Chinese institutions served to demonstrate the advances of some of the robotics companies, but it was also a clear demonstration of the limitations of these robots. As we said, these companies do not design these robots with this type of purpose, and specialization is usually a key aspect of current robots. However, this half marathon serves to boost new ideas among robots developers, which should undoubtedly pursue that intensive motor capacity for their projects.

JPMorgan has managed to generate really random numbers. The questions are what he needs them for and how he has done it

A classic computer cannot generate Really random numbers. The algorithms used in computer science to produce this type of numbers resort to an initial value usually known as “seed”, so that making mathematical calculations with it is possible Generate one or several pseudo -elementary numbers. In this context it is necessary to use the ‘pseudo’ prefix because the need to resort to that initial value, to that seed, causes the numbers that we obtain Don’t be really random. In fact, when taking the seed we have several options. Some algorithms resort to the system clock, and it is even possible to increase the apparent randomness of the generated numbers sequence using entropy sourcessuch as the mouse movement or the temperature of the CPU in a certain moment. Even so, the numbers that we will obtain will not be really random because it is possible to predict them if we know the seed and the operations that have been carried out to generate them. Quantum computers, rescue For the gigantic American financial conglomerate JPMorgan the random numbers are very important. A priori may seem strange that a bank is interested in the procedures for generating this type of numbers, but, in reality, this capacity lies in the heart of their business. And it is that random numbers are fundamental in cryptography techniques Employees, for example, to transmit encrypted information, work with cryptocurrencies, develop gambling, and, in general, in any process in which it is necessary to have a randomly as possible randomness. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by Quantinuum For this reason, in May 2023, several JPMorgan cryptographers wrote an algorithm of random generation generation that was designed to be executed in a quantum computer. Its strategy was to take advantage of the randomness inherent in the behavior of the cubits, whose functioning is governed by The rules of quantum physics, To generate bits whose randomness It could be proven afterwards. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by the American company Quantinuum, which belongs to Honeywell. And it worked. They have detailed the result of their experiment in a very interesting article that they have published in Nature. To check if the numbers given by their quantum algorithm are really random JPMorgan researchers worked side by side with scientists from the National Argonne Laboratory, the National Laboratory OAK RIDGE and the University of Texas in Austin. In Your article develop the method they have used to Mathematically demonstrate using super -touches of the US Department of Energy that the numbers delivered by the quantum computer are genuinely random. “It is a revolutionary result (…) the next step requires understanding where we can apply this technology,” Asses Marco Pistoialeader of the project and head of applied research in Global Technology of JPMorgan.

Maybe you just need to ask yourself the five appropriate questions

Face one crowded with tasks Oa a large project can become intimidating. Therefore, when you feel that you block yourself and your productivity stagnates, it may be a good idea to rethink if you really find yourself In a productivity bump Or yes, really, those tasks are as priority as you think. Stop, step back and analyze the stage is the best way to optimize the processes to move forward, dedicating energy to what really matters to achieve the objectives and leave aside what does not. The key is to be done The right questions. When was the last time you felt productive? People are not machines, so productivity does not remain unchanged and suffers up and down throughout the week or months. It depends on your physical, emotional state. Ask that question allows you to define productivity scenarios in the past, which may not be given in the present. Remember when was the last time you felt Your productivity had shot and analyze that scenario can help you replicate that scenario in the present and promote a situation in which your productivity returns to its acceptable levels. If, for example, it was before a vacation, given the urgency of closing the fronts open before going vacation, it could be justified with The Yerkes-Dodson Lawand you need a certain voltage component that motivates you. Maybe your productivity improved when you had a well -defined goal and allowed you to focus 100% on it, instead of dispersing your attention in secondary tasks. What is the purpose of this? The day -to -day inertia often puts trees on the road that prevent seeing the full forest. One of those “trees” are the smallest and most monotonous tasks for which it is difficult to find a motivation to do. Zero of the mail, wash the dirty dishes or introduce the data of your expenses in a spreadsheet may seem boring and unproductive tasks when analyzing themselves, but acquire importance when contextualize in a broader objective. Zeroing your email tray does not have an immediate effect on your productivity since it does not make your task list It is completed faster. Instead, it does allow you to locate the important emails for your project and respond efficiently. Similarly, wash the dishes As you get dirty It serves to use less time preventing them from accumulating, in addition to avoiding health and order problems. In the same way, something as little appealable as bringing daily control of expenses It serves to improve your economy and Facilitate savings. There are only three examples of tasks that, in themselves, may seem unnecessary and totally postponable, but that have a much more important objective. It’s just a matter of giving them perspective. Why don’t I want to do this? The procrastination is A psychological phenomenon Fascinating, because whoever suffers it is totally aware of the suffering that will cause it to postpone tasks, but cannot avoid doing so. Fuschia M. Siroisprofessor of the Department of Psychology at the University of Durham, declared to The Washington Post: “Procrastination has to do with emotional self -regulation and, in particular, with the inability to handle negative moods around a certain task.” In general, we do not postpone the fun things, we procrastine in tasks that we consider “difficult, unpleasant, aversive or simply boring or stressful,” said the teacher. Find the Origin of procrastination that causes that task is one of the keys to recover productivity and face Strategies to mitigate that blockade. It may be because the task seems boring, because it is so great that facing it produces anxiety or, simply, because it does not align with your opinion. Can I break this project more? One of the most common productivity problems is the blockade that occurs before a project that we consider to surpasses us. There are so many things to do, that the focus is lost and you scatter. The best strategy to face is “Divide and win”: break down a very big task in others much smaller and assumed. For themselves, these tasks do not imply a substantial advance in the project, but as the sayinger says: “Grain does not make a barn, but helps the partner”, so that, when completing small tasks, the main project is being completed. Become your own assistant It is also a very useful technique to unlock those tasks that, for some reason, you resist facing. This technique is to prepare everything necessary (materials, data, knowledge, etc.). Once all the pieces gathered, you just have to take the step of joining them, reducing the friction of the beginning. Is this task really necessary? This is a fairly dangerous question because it requires to put the task in a certain context of priorities with respect to other tasks, and there is a risk that the Conditioning of procrastination Do not lead to an erroneous self -suction conclusion. I do not want to do it, it is not necessary. Taking that into account, it should be put on the table A priority scale And consider whether to complete a certain task is a priority to advance your project. It does not imply that the task should not be done. The question is, should you do now, today or do you have to do it? Eliminating these tasks or prioritizing others will allow you to concentrate better in your day and advances in your goal. To establish these priorities you can use task lists systems such as ABCDE METHOD. Another approach to avoid unnecessary tasks or that do not contribute to improving your productivity is simply, say no. Assume tasks that distract your attention or do not correspond to youmake your daily planning be filled with tasks that do not help you achieve your goals. The most common result is to have that feeling of not having stopped throughout the day, but you have not achieved your goals. Does it sound to you?
