         Em 1914, uma expedição estudantil saiu da Rússia em direção à América do Sul, sendo considerada a segunda campanha científica da Rússia no continente depois da longa viagem do barão Langsdorff pelo interior do Brasil na primeira metade do século XIX. O empreendimento foi enviado pelo Museu de Antropologia e Etnografia de São Petersburgo e integrado por cinco jovens cientistas, sendo dois zoólogos, dois etnógrafos e um antropólogo, cujo objetivo era a coleta de material de valor biológico e etnográfico para compor coleções nas instituições que participaram de seu financiamento. A expedição passou por países como Brasil, Paraguai e Argentina, resultando em amplo material manuscrito e algumas publicações, além dos objetos coletados.

    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.

    Back To School But Not To Screens: States Ramp Up Cellphone Bans




            Work has been easier for public high school teacher Brian Kerekes since last August, when he first experienced the impacts of a newly enacted Florida law to restrict students’ cellphone use during class. The longtime statistics instructor, who started a new school year on Monday, now spends less time circling the classroom policing students and more time educating them on how to gather and interpret data.



            Before Florida passed the ban in May 2023 — becoming the first of at least eight U.S. states to prohibit or restrict cellphone use in schools — phones proved a constant disruption in Kerekes’ classroom at Tohopekaliga High School in the central Florida city of Kissimmee.



            “Students were either using them to talk to someone in a different class or talk to someone on the other side of the room or just to zone out, get on TikTok or whatever,” Kerekes, who's been a teacher for 17 years, said in an interview.



            Fellow teachers nationwide face the same challenge, which explains why more states and districts are moving to limit or outright ban cellphones in the classroom, and even during the school day altogether.

            


            The rules will look different from state to state and district to district, but all stem from the same concerns.



            Seventy-two percent of high school teachers cite cellphones as a major distraction in the classroom, according to a fall 2023 Pew Research Center study. Educators also worry that constant access to social media can adversely impact kids’ mental health.



            U.S. Surgeon General Vivek Murthy went so far as to issue a health advisory last year, warning that enough evidence exists to show social media can be unsafe for children and teens. “We are in the middle of a national youth mental health crisis,” he said, “and I am concerned that social media is an important driver of that crisis, one that we must urgently address.”



            While social media can connect kids, make them feel less alone and offer an entertaining and creative outlet, it also exposes them to harmful content, Murthy pointed out in the advisory released by the U.S. Department of Health and Human Services. And, as educators such as Kerekes note, some students use their phones to bully fellow students online during the school day, and in the most extreme cases, to set up fights and film them.

    The hope is that cellphone bans will reduce such incidents. Kerekes said he’s hearing they have.
