    Bill Gates and his vision of the future of jobs with AI

    By Clément Pessaux

    April 29, 2025


    According to Bill Gates, artificial intelligence is about to redefine the job market. Among the professions likely to be widely replaced, Gates directly mentions doctors and teachers. Why these specific sectors? AI has the ability to take on complex tasks such as medical diagnosis or personalized learning, making these services more accessible. In fact, in some developing countries where access to education and healthcare remains limited, such advancements could transform daily life.

    But this progress raises concerns. Can we really do without human empathy in these fields? And what about the judgment or sensitivity that a machine can never fully reproduce?

    On the other hand, there are professions that AI does not seem ready to replace. Gates specifically mentions energy experts, biologists, and developers. These jobs require specialized expertise, as well as creativity and constant adaptability in the face of environmental or technological challenges.

    Creativity, strategic thinking, and empathy remain areas where humans will always have the upper hand. Although he recognizes the immense potential of AI, Gates also emphasizes the limits and the need to think about its deployment by keeping humans at the center of priorities.

    The rise of reusable rockets: transforming the economics of space travel

    By Adam Stockley


    Various theoretical designs of reusable launch vehicles (rockets) have been tested during the history of space flight, but they generally proved too expensive or impractical to implement.  

    In the 21st century, the rise in industry privatisation led to several companies taking the lead in reusable launcher development. Their focus is on fully-reusable systems.

    The potential of reusable rockets to transform the economics of space travel should be evident. Even so, let’s break down the benefits and drawbacks of this technology to understand more.


    The Benefits of Reusable Rockets


    The most obvious benefit of a reusable rocket is cost savings. Unsurprisingly, it’s much cheaper to refurbish and relaunch a rocket than it is to build a new one. Reusable rockets also use less fuel than their expendable counterparts, making them comparatively better for the environment.


    The Drawbacks of Reusable Rockets


    The main disadvantage of reusable rockets is their reduced load capacity. By extension, they must be built to survive the difficulties of launch and re-entry, meaning there is much more extra stabilisation equipment. Therefore, the rockets are heavier.


    The Long-Term Viability of Reusable Launchers


    The bottom line is that now we have a firmer understanding of the concept of reusable launchers, their potential impact is limitless. However, there are some issues to resolve in terms of extra weight and reduced load capacity, but the space industry is very near to perhaps its biggest revolution in terms of cost reduction and accessibility.

    The problem with artificial intelligence? It's neither artificial, nor intelligent.




        Elon Musk and Apple's co-founder Steve Wozniak have recently signed a letter calling for a six-month moratorium on the development of AI systems. The goal is to give society time to adapt to what the signatories describe as an “AI summer”, which they believe will ultimately benefit humanity, as long as the right guardrails are put in place. These guardrails include rigorously audited safety protocols.



        It is a laudable goal, but there is an even better way to spend these six months: retiring the hackneyed label of “artificial intelligence” from public debate.


    [...]

        However, many critics have pointed out that intelligence is not just about pattern-matching. Equally important is the ability to draw generalisations. Marcel Duchamp's 1917 work of art Fountain is a prime example of this. Before Duchamp's piece, a urinal was just a urinal. But, with a change of perspective, Duchamp turned it into a work of art. At that moment, he was generalising about art.


    [...]

        Human intelligence is not one-dimensional. It rests on what the 20th-century Chilean psychoanalyst Ignacio Matte Blanco called bi-logic: a fusion of the static and timeless logic of formal reasoning and the contextual and highly dynamic logic of emotion. The former searches for differences; the latter is quick to erase them. Marcel Duchamp's mind knew that the urinal belonged in a bathroom; his heart didn't. Bi-logic explains how we regroup mundane things in novel and insightful ways. We all do this — not just Duchamp.



        AI will never get there because machines cannot have a sense (rather than mere knowledge) of the past, the present and the future; of history, injury or nostalgia. Without that, there’s no emotion, depriving bi-logic of one of its components. Thus, machines remain trapped in the singular formal logic.


    [...]

        But the reason why tools like ChatGPT can do anything even remotely creative is because their training sets were produced by actually existing humans, with their complex emotions, anxieties and all. If we want such creativity to persist, we should also be funding the production of art, fiction and history — not just data centres and machine learning.



        That’s not at all where things point now. The ultimate risk of not retiring terms such as “artificial intelligence” is that they will render the creative work of intelligence invisible, while making the world more predictable and dumb.



        So, instead of spending six months auditing the algorithms while we wait for the “AI summer,” we might as well go and reread Shakespeare’s A Midsummer Night’s Dream. That will do so much more to increase the intelligence in our world.



    Fonte: MOROZOV, Evgeny. The problem with artificial intelligence? It’s neither artificial nor intelligent. The Guardian, 30 mar. 2023. Disponível em: https://www.theguardian.com/commentisfree/2023/mar/30/artificial-intelligence-chatgpt-human-mind

    The decline of teenagers reading is an impact on education




            If you are a teenager reading this story, you are in the minority. Statistics show that 80% of teenagers do not read for pleasure on a daily basis. It is no coincidence that the teenage reading rate has declined as technology and social media have taken over nearly all aspects of teenage life. With the downfall of teenage reading, may come the downfall of teenage education altogether.



          With technology taking over the world, teenagers have all the knowledge they need and more right at their fingertips. There is no reason for people to open up nonfiction books anymore when they can simply pull out their phones and find any information on any topic. The rise of technology has also dramatically affected the amount of fiction reading teenagers do as they would rather watch YouTube or keep up with their friends on Instagram than read an all-time classic like Harry Potter or Lord of the Rings.



            Speaking of all-time great books, it seems like just about every bestseller has been turned into a movie that either gives the book a bad rap or receives great reviews and overshadows the book. Why would anyone read a book for days or even weeks when they can just watch the movie in one sitting?



            Teenagers have also stopped reading because of the amount of homework they are given, including any school-assigned reading. When students are forced to read particular books in school that they may not be interested in, they begin to associate reading with work instead of pleasure or entertainment. Reading books also always seems to take longer when it is one you are not interested in, which is often the case with school-assigned books.

    No matter how boring teenagers find reading, its decline could have direct consequences for all teenagers and their education. Reading is a major part of school, and without the ability to read at a high level students could find it impossible to learn anything at all. From history textbooks to English literature, reading is used in nearly every class of every school and is essential to getting a good education.

            The voluminous literature dealing with the idea of human progress is decidedly a mixed bag. While some of these writings are impressive and even inspiring, many of them are superficial, perhaps even ridiculous, in their reiteration (especially during the nineteenth century) of the comforting prospect that every day in every way we are growing better and better.



            This kind of foolishness is manifested especially in discussions of such matters as economic, political, and moral progress, and of progress in art. [...]



            From time to time, there seems to be real and measurable improvement in these areas. At other times the opposite seems equally to be the case. Thus the fervent belief of writers like the French sociophilosopher Auguste Comte in the inevitability of progress in all fields of human endeavor must be viewed as insupportable. We cannot accept it any longer, even if we once thought it was true.



            Progress in human knowledge is another matter. Here it is possible to argue cogently that progress is in the nature of things. “Not only does each individual progress from day to day”, wrote French philosopher, mathematician, and mystic Blaise Pascal, “but mankind as a whole constantly progresses... in proportion as the universe grows older.” The essence of man as a rational being, as a later historian would put it, is that he develops his potential capacities by accumulating the experience of past generations.



            Just as in our individual lives we learn more and more from day to day and from year to year because we remember some at least of what we have learned and add our new knowledge to it, so in the history of the race the collective memory retains at least some knowledge from the past to which is added every new discovery.



            The memories of individuals fail and the persons die, but the memory of the race is eternal, or at least it can be expected to endure as long as human beings continue to write books and read them, or — which becomes more and more common — store up their knowledge in other mediums for the use of future generations.

    Turn Employee Feedback into

        Action Enhancing how a company supports and engages its employees can attract talent, improve retention, spur innovation, and increase customer satisfaction. But managing the employee experience for maximum benefit requires leaders to know what employees are seeing, feeling, and wanting — and then respond judiciously. Driven by a tight labor market, corporate leaders have recently invested enormous amounts of energy and resources in collecting employee feedback through pulse surveys, town halls, listening tours, focus groups, data scraping from message boards, and other methods. The problem for many leaders is that when they ask what employees think, they don’t know what to do with what they hear — they often struggle to translate all this input into meaningful insights and concrete actions. A gap between accumulating the information and taking coherent action to respond can diminish the value of employee feedback over time — and if it persists, employees may stop responding.

    How can neuroscience lead to treatments for nicotine addiction?
    Around a billion people still smoke, so we clearly have more to learn about effective treatments for nicotine addiction. Medications that can help include bupropion, a classical antidepressant, which mostly helps people who are depressed to stop smoking; and varenicline, which imitates nicotine in some ways but prevents nicotinic receptors from being fully activated.
    Some nicotine cessation products, such as gums and patches and inhalers, use nicotine itself in the hope that it can be delivered in small enough quantities and over a long enough period of time that nicotine receptors will only be partially chaperoned, helping to reduce upregulation while the individual works on quitting smoking.
    We still need more and better science to figure out the pharmacokinetics of nicotine: How fast does it enter the body? How long does it stay in the body? To that end, along with a team of collaborators — including Caltech professors Wei Gao (professor of medical engineering), Dennis Dougherty (George Grant Hoag Professor of Chemistry), and Stephen Mayo (Bren Professor of Biology and Chemistry), and Professor Neal Benowitz of UC San Francisco — we have been working to develop a wearable device that resembles the continuous glucose monitor used by Type 1 diabetes patients.
    We will use this monitor to measure nicotine while a person smokes or vapes or uses a nicotine pouch so that we can fully understand how an individual metabolizes nicotine and relate this knowledge to a century’s worth of work on nicotinic receptors and nicotine addiction.

    INSTRUCTION: Read the following text to answer the question.

    What happens in the brain when people smoke?
    When nicotine enters the lungs, it’s in the brain 20 seconds later. In this journey, nicotine has traveled through the cells in the lungs to the blood — and then from the blood to the brain, passing through the blood‑brain barrier. In all, nicotine passes through six membranes when it’s smoked or vaped.
    Once nicotine is in the brain, it activates the most sensitive nicotinic receptors on membranes of nerve cells, or neurons, but it also travels through the membrane to enter the neuron. Finally, it passes into the organelles of the neuron, where proteins, including the nicotinic receptor, are being made. When a person smokes, nicotine actually helps the cell to assemble more nicotinic receptors, which travel out of the endoplasmic reticulum (part of the cellular transportation system) and onto the surface of the cell. It’s as though nicotine is acting as a pharmacological “chaperone” to bring those receptors to the surface of the cell.
    We have labeled this process “inside out” pharmacology. In trying to unravel the cell biology of nicotine addiction, my lab and others study how this so‑called chaperoning or upregulating of nicotinic receptors is necessary for the early stages of nicotine dependence, ultimately underlying the brain’s addiction to nicotine. When a person stops taking nicotine, the natural acetylcholine cannot sufficiently activate the upregulated receptors. They produce craving and other symptoms of withdrawal.

    Read the following text.

    Henry Lester, professor of biology at Caltech, discusses the effects of nicotine addiction on the brain.

    Tobacco originated in the Americas, where humans have known some of its effects for at least 10,000 years. Beginning some 500 years ago, ocean crossings spread tobacco use to all other continents. We are essentially the only species that has learned how to use small amounts of plant toxins — which provide the selective advantage of sickening or poisoning animals who might eat them — for our own purposes. For tobacco, that toxin is nicotine. In addition to their historical medicinal and ritual uses, these substances, over time, have come to serve as guides, models, and touchstones for learning about the brain and opening many fields of neuroscience.

    We have learned from tobacco and nicotine that it is possible to isolate single chemicals from plants that cause toxic effects on herbivores and valued effects on people. We’ve learned that it’s possible to define chemical processes in the human brain that are activated, inhibited, or otherwise manipulated by those substances.

        Recent research suggests that about one in seven life-threatening allergic reactions are caused by foods not currently listed on mandatory allergen labels.

        Food allergies are rising, yet regulations, such as the European Union’s 14-item allergen list from 2011, have not been updated in years.

       To identify overlooked triggers, Dominique Sabouraud-Leclerc and colleagues analyzed 2999 cases of food-induced anaphylaxis reported between 2002 and 2023 to the Allergy-Vigilance Network. They found that goat or sheep milk, buckwheat, peas, lentils, pine nuts, kiwi, apples, beehive products and alpha-gal (a sugar that can trigger an allergy to red meat and other mammalian products) were responsible for about 14% of reactions. Goat and sheep cheese caused particularly severe outcomes, including two deaths, and hidden exposures in processed foods increased risks.

          Based on these findings, the researchers recommend adding goat and sheep milk products, peas, lentils, buckwheat and pine nuts to Europe’s mandatory allergen labelling. They argue that clearer information is crucial for protecting allergic individuals and could inspire broader international policy updates.

    What is nomophobia?


    Nomophobia refers to a fear of not having mobile phone connectivity. It can cause panic or anxiety for the person experiencing it.

    Researchers have noted that it is still unclear if the disorder comes from an existing condition, such as anxiety disorder, or from a cell phone addiction. They proposed changing the name “nomophobia” to “smartphone addiction disorder.”

    Treatments are currently nonstandard and involve behavioral therapies, support groups, and self-care.

    Self-care

    A person can practice self-care strategies on their own. They can take the following steps to manage their phobia:

    • progressive muscle relaxation

    • practicing different breathing techniques

    A person may also benefit from learning relaxation techniques. This therapy involves a combination of breathing techniques, exercises, and meditation techniques, which help a person cope with not having a phone or other phobias.

    What links Sir Isaac Newton, alien solar systems, and a new multi-million dollar TV show? The answer is “the three-body problem”: a conundrum in astronomy and mathematics that describes why it’s often difficult to predict the long-term trajectory of planets, moons and stars. So, what exactly is the problem? And how did it end up becoming the title of a TV series?


    To understand, you first need to know a bit about the background to the TV show and its premise. The story is based on Liu Cixin’s epic sci-fi trilogy, The Remembrance of Earth’s Past, of which The Three-Body Problem is the first book. The original trilogy is characterised by the author’s attention to scientific detail. The adaptation is less so, but still crammed with scientific ideas.


    The TV series focuses on the “Oxford Five”, who all studied under the same professor at the University of Oxford. Some have gone on to become scientists themselves (a postdoctoral physics researcher, a founder and chief scientific officer of a nano-tech company, and a theoretical physics academic), one has become a school physics teacher, while the fifth is now a snack-food entrepreneur. Scientific credentials abound.


    The crux of the story is that an alien race — called the Trisolarans or San-Ti Ren — is headed to Earth to colonise it. Through intergalactic communication, these travellers attempt to intimidate human scientists into slowing down our rapid technological advancement, making Earth easier to conquer. But why are these aliens so hell-bent on taking over our planet in the first place? This is where the three-body problem comes in.


    Bodies, in this context, is a scientific byword for planets, moons, suns or any other massive astronomical object. The extraterrestrials’ home planet is situated in a solar system with three suns, hence their name in the English translation of the book — the Trisolarans. This three-sun system can be highly unstable, making conditions difficult for life, hence the desire to travel across the Universe in order to inhabit our relatively stable Solar System. We only have one Sun, so Earth’s future is relatively predictable — at least for the next few million years.

    What links Sir Isaac Newton, alien solar systems, and a new multi-million dollar TV show? The answer is “the three-body problem”: a conundrum in astronomy and mathematics that describes why it’s often difficult to predict the long-term trajectory of planets, moons and stars. So, what exactly is the problem? And how did it end up becoming the title of a TV series?


    To understand, you first need to know a bit about the background to the TV show and its premise. The story is based on Liu Cixin’s epic sci-fi trilogy, The Remembrance of Earth’s Past, of which The Three-Body Problem is the first book. The original trilogy is characterised by the author’s attention to scientific detail. The adaptation is less so, but still crammed with scientific ideas.


    The TV series focuses on the “Oxford Five”, who all studied under the same professor at the University of Oxford. Some have gone on to become scientists themselves (a postdoctoral physics researcher, a founder and chief scientific officer of a nano-tech company, and a theoretical physics academic), one has become a school physics teacher, while the fifth is now a snack-food entrepreneur. Scientific credentials abound.


    The crux of the story is that an alien race — called the Trisolarans or San-Ti Ren — is headed to Earth to colonise it. Through intergalactic communication, these travellers attempt to intimidate human scientists into slowing down our rapid technological advancement, making Earth easier to conquer. But why are these aliens so hell-bent on taking over our planet in the first place? This is where the three-body problem comes in.


    Bodies, in this context, is a scientific byword for planets, moons, suns or any other massive astronomical object. The extraterrestrials’ home planet is situated in a solar system with three suns, hence their name in the English translation of the book — the Trisolarans. This three-sun system can be highly unstable, making conditions difficult for life, hence the desire to travel across the Universe in order to inhabit our relatively stable Solar System. We only have one Sun, so Earth’s future is relatively predictable — at least for the next few million years.

    Making family medicine a more attractive specialty: strategies to address the shortage of primary care specialists in Brazil



    Primary Health Care (PHC) is often the first level of the health system and is responsible for the coordination of medical and interdisciplinary care. As the preferred entry point to the Brazilian Unified Health System (SUS), PHC is of fundamental importance and is present in all regions of the country. It aims to enable access to health care and ensures the coordination and completeness of care. This structure can treat approximately 80% of the overall need related to diseases presented in the Basic Health Units.


    Despite its importance, the valorization of PHC and Family Medicine (FM) as a discipline and a public policy has not been prioritized in most Brazilian educational institutions. According to the study on medical demography carried out by the Regional Medical Council of São Paulo (CREMESP), Brazil had 500,000 physicians in 2020, but with unequal distribution among the nation’s five regions, and a concentration of professionals in the capital cities compared to the countryside.


     This issue is faced by many countries. In the United States (US) of 8,116 primary care postgraduate training positions (which includes pediatrics, internal medicine, and family doctors), 42 percent were filled by graduates of U.S. medical schools and the American Association of Medical Colleges (AAMC) projects a shortage of 21,100 to 55,200 primary care physicians (PCP) by 2034. In Europe, where PCP was traditionally respected and recognized, the lack of General Practitioners (GP) is also increasing and is a matter of concern. Workload and a lack of perceived prestige associated with the PCP track can make primary care less attractive. These sorts of misconceptions, along with lower salaries, burnout, and difficult career advancement makes primary care a difficult specialty to attract and retain doctors.


    For Feuerwerker, vacancies in Brazilian institutions are the result of several elements: the encouragement of distinctive specialties and institutions, the historical misunderstanding and importance of the practice, and the increased incentive of specialization in medical education. The lack of investments in supplies and infrastructure in primary care, career development concerns, and low salaries, and the valorization of the formation of FM doctors in the work of the EFS also contribute to difficulty in retaining these positions in Brazil.


    With the aim to reduce the vacancy rate in the medical residency programs for FM, some Brazilian health departments introduced reforms and additional financing for FM training. In 2020, the region of Campinas, where we work, introduced a program called “More Doctors for the City of Campinas” (PMMC), which established a partnership between public and private higher education institutions, hospitals, and Urgency/Emergency Units with a novel post-graduation proposal for FM. It created a program to support the training of specialists in family medicine, stimulate research, and expand care in Basic Health Units, and has since resulted in a 50% decrease in vacancies.


    One of the successful elements of the Campinas program, together with quality of medical training, is that it helps bring medical classroom training closer to the community and everyday social reality. PMMC-trained physicians are aware of how their work impacts the local community and its particular health needs. The program has resulted in care that is more responsive to community needs, especially from the perspective of adopting a care model that prioritizes health promotion, disease prevention, diagnosis, and treatment in an integrated manner. However, for the EFS to continue to innovate and improve its response capacity to contemporary health problems, it must invest heavily in professional training, the rational incorporation of information and communication technologies, and the creation of appropriate working conditions for multidisciplinary teams.
