🚨BREAKING: Researchers just confirmed something the AI industry does not want you to know.
AI is making professionals worse at their jobs when the AI is not available. Not slower. Not less confident. Measurably worse.
A study published in The Lancet Gastroenterology and Hepatology tracked doctors performing colonoscopies across four hospitals in Poland after AI assistance was introduced into the procedure. Then the researchers measured what happened when the doctors performed the same procedure without AI help.
Adenoma detection rates dropped from 28.4% to 22.4%. A six-point absolute decline. The AI was not present. The doctors were. But continuous reliance on the AI had eroded the observational skill the procedure requires. Real patients with real polyps were missed because the doctors had stopped practicing the part of their job the AI had been doing.
This is not an isolated finding. Researchers at Microsoft and Carnegie Mellon University surveyed 319 knowledge workers and presented the results at CHI 2025, the premier academic conference on human-computer interaction. Workers with higher confidence in AI tools reported lower confidence in their own critical thinking. The pattern was consistent. The more someone relied on AI to produce outputs, the less cognitive effort they reported applying to the work itself.
A separate study from SBS Swiss Business School published in January 2025 surveyed users across age groups and found a statistically significant negative correlation between AI usage frequency and critical thinking scores. Younger users were more affected than older ones. The MIT Media Lab reached the same conclusion in a study on cognitive atrophy. A study published in October 2025 in Computers in Human Behavior found that AI use makes people overestimate their own cognitive performance. They get smarter outputs and dumber self-awareness simultaneously.
The mechanism has a name. Cognitive offloading. The brain stops practicing tasks it has delegated to a system. Active skills become passive ones. The AI performs the task. The human approves the output. Over time the human loses the ability to perform the task without the AI.
The Lancet study made this visible because the stakes were measurable. A doctor either finds the polyp or does not. But the same dynamic is happening across every professional field where AI has taken over routine cognitive work. UX designers reported it for prototyping and bias detection. Cybersecurity analysts reported it for threat reasoning. Knowledge workers reported it for analysis and synthesis.
The implication is structural. Entry-level roles historically existed not just to produce output but to develop judgment. The junior analyst ran the numbers because doing so taught them what the numbers meant. The junior associate drafted the brief because doing so taught them how arguments are constructed. AI is absorbing those tasks at exactly the point where the next generation of professionals would normally be building the skills they need at the senior level. There is a direct line between the Lancet study and the Anthropic finding that young worker hiring in AI-exposed fields has dropped 14%. The tasks are not being practiced. The judgment is not being developed.
The researchers are not arguing against AI. They are documenting a specific harm that does not show up in any productivity metric. The output looks better. The human producing it has gotten worse.
If you have been using AI for the work you used to do yourself, the studies suggest you are not just saving time. You are losing the ability to do that work without it.

🚨BREAKING: Two researchers from UPenn and Boston University just published a paper that should be uncomfortable reading for every CEO automating their workforce right now.
The argument is straightforward. Every company replacing workers with AI is also eliminating its own future customers. Laid off workers stop spending. Enough of them stop spending and nobody can afford to buy anything. The companies that fired everyone end up selling into an economy with no purchasing power left.
Every executive can see this. The math is not complicated. But here is why nobody stops.
If you do not automate, your competitor does. They cut costs, lower prices, take your market share, and you collapse anyway. So every company automates knowing it is collectively destructive because the alternative is dying alone while everyone else survives. The researchers proved this is a Prisoner's Dilemma playing out in real time.
The numbers are already moving. Block cut nearly half its 10,000 employees this year. Jack Dorsey said AI made those roles unnecessary and that within the next year the majority of companies will reach the same conclusion. Salesforce replaced 4,000 customer support agents with AI. Goldman Sachs deployed a coding tool that lets one engineer do the work of five. Over 100,000 tech workers were laid off in 2025 and AI was cited as the primary driver in more than half those cases. 80% of US workers hold jobs with tasks susceptible to AI automation.
The researchers tested every proposed solution. Universal basic income does not change a single company's incentive to automate. Capital income taxes adjust profit levels but not the per-task decision to replace a human. Collective bargaining cannot hold because automating is always the dominant strategy.
They also identified what they call a Red Queen effect. Better AI does not solve the problem, it accelerates it. Every company chases faster automation to gain market share over rivals but at the end everyone has automated equally, the gains cancel out, and the only thing left is more destroyed demand.
The one thing the math says could work is a Pigouvian automation tax. A per-task charge that forces companies to account for the demand they destroy each time they replace a worker.
The conclusion is that this is not a transfer of wealth from workers to owners. Both sides lose. Workers lose income. Companies lose customers. It is a deadweight loss with no market mechanism to stop it on its own.

En 2019 ASSE gastaba unos 15 millones de dólares en contracciones al Círculo Católico.
Al finalizar la gestión de Cipriani y Lacalle, en 2024, las contrataciones al Círculo Católico pasaron a 65 millones de dólares.
Escandaloso.

Una pena q la presentación de la noticia no aclare q el error fue cometido en la anterior administración (febrero de 2025).
Sin drama: hay errores, y se corrijen.
Eso sí, muy mal lo de Mieres y Delgado, denunciando infundadamente una inexistente manipulación.
Eso sí q es grave.
Más blancos denunciados por corrupción, en los juzgados son como de la familia.
Con todas las denuncias de los últimos 5 años, se debería crear una fiscalía especializada en delitos de los políticos del partido nacional.
Que CANETADA ABSURDA do Presidente Lula desmascarando a extrema direita para o mundo. Uma frase mais perfeita que a outra:
“Se dizem patriotas, mas põem a soberania à venda e pedem sanções contra o próprio país”
“Proclamam defender a família, mas fecham os olhos para a violência contra as mulheres e o abuso sexual de crianças”
“Se declaram donos da verdade, mas espalham mentiras e desinformação”
“Se consideram homens de Deus, mas não têm amor ao próximo”
“Falam em liberdade, mas perseguem quem é diferente”
Perfeito 👏🏾
@GroseroKesman Esto es vergüenza 👇
En el 2004 dejaron 300 mil personas en la más absoluta miseria (8% de indigencia) y 1,5 millones de compatriotas por debajo de la línea de pobreza (40% de pobreza). Quizás tú estabas entre ellos.
Ese es el legado de la derecha, rompieron el entramado social.
@luispereirat@olgasuarez2@sportobeledo@bettianadiazrey Querido cuál argumento querés sobre el gobierno anterior
Que intendencia blanca querés que nombre con problemillas (delincuentes)
Uruguay no es un país serio
En cualquier estado de derecho real
Estarían todos presos
Partido nacional narco
No, Javier, estás recontra equivocado.
Aumentaron las penas mínimas por delitos de narcotráfico, incluidos los de micro, insignificantes.
Los Jueces se quedaron sin herramientas para aplicar medidas alternativas.
Se llenó la cárcel de mujeres, principalmente, vulnerables y presionadas por sus parajes privadas de libertad. Se rompieron hogares pobres.
No mejoró la seguridad, solo se puso más gente en cana, que no es lo mismo.
Y todo esto para que Uds. puedan publicar dos tuits efectistas, que se parecen más a un slogan que una propuesta política superadora.
Martinelli habla más ahora en prensa que el rato en que fue ministro.
De un senador lúcido y experimentado como vos, esperamos un debate conceptual, serio y sin enojos. O, por lo menos, un poco de responsabilidad desde tu rol de oposición y ex ministro de defensa.
No los esperamos chicos‼️
Empezamos sin ustedes‼️
Después no anden tirando piedras y poniendo palos en la rueda‼️
Blancos, colorados e independientes no participarán de comisión organizadora del Congreso Nacional de Educación
Pdt. Que renovación ehh👇
@leosarro Siguen apareciendo casos de corrupción en sus filas y tiene que salir al grito con boludeces para tapar otro nuevo caso de delincuencia blanca!!
NO aceptaron el pedido de no firmar contratos dos días antes del fin de su gobierno.
NO le dieron ni dos días de luna de miel a la nueva administración.
NO avalan ninguna iniciativa oficialista.
NO participan de los diálogos democráticos.
Es la derecha antidemocrática uruguaya.
**Lula da Silva le está "dando duro" al mundo entero y arrastrando por el suelo la dignidad de Netanyahu! 🇧🇷🔥**
El presidente brasileño Lula da Silva ya no se aguanta más y soltó un discurso cargado de balas directas contra el Parlamento Europeo y todos los que se quedan callados ante la masacre que está ocurriendo. Les dijo dos verdades que necesitan escuchar y digerir:
🔴 “Cada día me despierto y me sorprende el tamaño de esta destrucción, y todo viene de una sola persona… ¡y nadie es capaz de juzgarlo ni ponerle un límite!”
🔴 “¿Dónde está ese derecho internacional del que tanto hablan cuando se trata de ‘Netanyahu’? Esa persona que pisa a la humanidad con sus botas, que disfruta de la destrucción y que parece desayunar con noticias de muerte y sangre.”
🔴 “¿Esto es justicia? ¿El derecho internacional solo saca músculo contra los débiles? ¿Lo único que les preocupa ahora es que se abra el estrecho de Ormuz y que no se afecte el comercio?”
🔴 “¿Por qué no vemos el mismo interés por la sangre de los pobres y los inocentes que están muriendo en Líbano que el que muestran por abrir el estrecho de Ormuz? Si esas son sus cuentas, entonces yo apoyo que Irán lo cierre… porque la vida de un solo ser humano vale mil veces más que ese maldito estrecho de Ormuz de ustedes.”
Una más. Recuerden que cómo parte de su campaña de oponerse a todo para polarizar y en 2029 resucitar como el candidato pendeviejo canchero, LACALLE POU ordenó a Ediles no votar préstamo de IM para obras de saneamiento y limpieza IMPOSTERGABLES. Tanta mezquindad afecta a vecinos en su calidad de vida, una vez más, cuando lo que menos debería importar es a quien votan. Ya mataron préstamo BID en período anterior. Los depredadores no paran.Lamentable
Too on point not to share, “Aussie reply to Trump rant about NATO not being there for us.
Mate. You run a country with 600,000 homeless people sleeping on the street tonight. A country where 40% of adults can't cover a $400 emergency without borrowing money. A country where insulin costs more than a car payment and people are rationing it to survive. A country where medical debt is the number 1 cause of bankruptcy. A country where women are dying in hospital car parks because doctors are too scared of abortion laws to treat a miscarriage.
You lock up more of your own citizens than any nation on earth. More than China. More than Russia. More than North Korea. The land of the free has 2 million people in cages, and a quarter of them haven't even been convicted of anything. They're just too poor to make bail.
Your life expectancy is going backwards. You're the only developed nation where that's happening. Your infant mortality rate is worse than Cuba's. Your kids do active shooter drills between maths and English while you sell the gunmaker's stock to your mates.
Your minimum wage hasn't moved in 15 years. You've got teachers working 2 jobs and veterans sleeping under bridges and you just spent a trillion dollars flattening a country that didn't attack you.
And you’ve got a convicted felon, adjudicating raping, paedophile protecting, porn star shagging insurrectionist running the biggest dumpster fire war campaign since the Taliban thanked you very much for losing again.
And you're calling Greenland poorly run?
Greenland has universal healthcare. Free education. One of the lowest incarceration rates in the world. Nobody goes bankrupt there because they got sick. Nobody dies in a waiting room because their insurance said no.
"NATO wasn't there when we needed them." When exactly was that, champ? September 11? Because NATO invoked Article 5 for the first and only time in history FOR YOU. Soldiers from dozens of countries deployed, fought, bled, and died in Afghanistan FOR YOU. Australia wasn't even in NATO and we still showed up. For 20 years.
And you pulled out at 2am without telling anyone and left them to deal with the mess.
So maybe before you start calling other countries poorly run, have a look at your own backyard, you spray-tanned aluminium siding salesman. The only thing poorly run in this picture is your fucking mouth. Credit (borrowed from) Jim Scroggins - original author 📷 unknown”
