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.

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.

De acordo com as informações do texto, é CORRETO afirmar que
Considere a seguinte equação:
Assinale a alternativa que contenha o valor de θ que satisfaça a equação.
Assinale a alternativa que contenha o valor que será reduzido na média salarial.
Dadas as afirmativas sobre os mecanismos de defesa do organismo e das vacinas,
I. A primeira linha de defesa do corpo é composta por mecanismos naturais como a pele, o muco e as enzimas salivares, que atuam impedindo a entrada de microrganismos.
II. A vacinação elimina os mecanismos naturais de defesa, tornando desnecessária a ação de células como linfócitos T e B.
III. As vacinas funcionam ao simular uma infecção, levando o sistema imunológico a produzir anticorpos e células de memória, sem causar a doença.
IV. Pessoas que não se vacinam podem representar um risco à saúde coletiva, pois podem se tornar portadoras e disseminadoras de agentes infecciosos.
verifica-se que está/ão correta/s
“A estiagem prolongada tem feito o Rio São Francisco perder força na divisa de Alagoas e Sergipe, permitindo que o mar avance sobre a água doce. O fenômeno é conhecido como salinização e, segundo pesquisadores da Universidade Federal de Alagoas (Ufal), está transformando o ecossistema da região e prejudicando a população ribeirinha. Sem chuvas e com menos água no leito, o rio acaba sendo empurrado pela maré nos pontos onde encontra o mar. É no trecho da Área de Preservação Ambiental (APA) da Foz do São Francisco, entre os municípios de Piaçabuçu (AL) e Brejo Grande (SE), que o fenômeno pode ser percebido com mais intensidade pelos quase 25 mil habitantes da região”.
Disponível em: https://g1.globo.com/al/alagoas/noticia/2017/03/mar-avanca-sobre-rio-sao-francisco-eafeta-populacao-ribeirinha-em-alagoas.html. Acesso em: 6 abr. 2025.
Esse cenário foi historicamente agravado por ações humanas, com a construção de barragens e a intensa retirada de água para irrigação, as quais reduziram o volume de água doce que chega à foz do rio.
Com base no texto e nos seus conhecimentos sobre a relação entre o ser humano e o meio ambiente, assinale a alternativa que representa, de forma mais adequada, uma consequência ecológica do processo de salinização na foz do Rio São Francisco, considerando-se as interações entre os componentes bióticos e abióticos do ecossistema.
Parasita A: ciclo heteroxênico (dois ou mais hospedeiros no ciclo de vida); o ser humano elimina ovos pelas fezes que eclodem na água e liberam larvas que infectam caramujos. Posteriormente, uma nova forma larval sai do caramujo e penetra ativamente pela pele humana.
Parasita B: ciclo monoxênico (único hospedeiro no ciclo de vida); cistos eliminados nas fezes contaminam a água e são ingeridos por novos hospedeiros, liberando formas ativas no intestino.
Assinale a alternativa que identifica corretamente os parasitas A e B, respectivamente, e justifica a relação de seus ciclos com a realidade socioambiental da região.
Dadas as afirmativas sobre fisiologia endócrina,
I. A exposição prolongada ao calor pode levar à disfunção das células de Sertoli e de Leydig, comprometendo tanto a espermatogênese quanto à produção de testosterona.
II. O aumento na produção de testosterona estimula a hipófise a aumentar a secreção de hormônio luteinizante (LH), como parte de um mecanismo de feedback positivo, com o objetivo de restaurar a homeostase.
III. O hormônio folículo-estimulante (FSH) atua diretamente nas células de Leydig, promovendo a síntese de testosterona, especialmente em condições de estresse térmico.
IV. Em ambientes com alta temperatura, a insuficiência na termorregulação escrotal pode comprometer a função testicular, o que pode desencadear alterações compensatórias no eixo hipotálamo-hipófise-gonadal por meio de mecanismos de retroalimentação negativa.
