Machines are tools, not persons. Today, some propose granting these systems rights, or even legal personhood. Such an approach risks obscuring human responsibility and leaving those who suffer harm to confront a faceless entity.

The future of #ArtificialIntelligence is not pre-determined. As a technology developed by human beings, its future depends on the choices we make. We therefore have the responsibility to guide, change and, when necessary, reject its applications. A reliable system that serves the human person is of greater value than one that is exceptionally powerful but whose consequences cannot be adequately foreseen or controlled.

La exposición de motivos tiene muchos gráficos interesantes pero hay uno clave para entender porque solo 20% de la reforma es recorte de gasto. Del aumento de gasto desde 2019 solo 0.5% corresponde a partidas discrecionales. Si fuera despilfarro, seria fácil de recortar, no?

¡Grave!
La Ley de rescate fiscal que acaba de radicar el ministerio de Hacienda permitiría eliminar los concursos anuales para ingresar a la @DIANColombia (contenidos en el Decreto Ley 927 de 2023) y regresar a la práctica de nombrar a dedo de miles de funcionarios.

If experts respond to AI this way, now imagine what a tremendously powerful indoctrination tool AI constitutes.

El #BorradorDeEconomía muestra que los modelos LLM (GPT-4º y Gemini 2.5 Pro) generan mejores pronósticos de inflación cuando, además de los datos históricos, incorporan información sobre lo que está ocurriendo en la economía en tiempo real. Al combinar gradualmente más datos, contexto económico y eventos recientes, las proyecciones se vuelven más realistas, consistentes y alineadas con la realidad económica en tiempo real.

A signature feature of academic AI writing is (currently) that it is has bad judgment on what is important and what is not important, even refine.ink.
This is one of the most damaging AI "tells", b/c it reflects bad judgment on the part of the author as well. 1/

🚨 New paper on AI and Copyright 🚨
It's easy to dismiss AI-written books 📚 as slop nobody buys. So, armed with full-text AI detection from @pangram, we studied self-published genre fiction books sold on Amazon from 2023 to 2026 March
Turns out Amazon is flooded with books with substantial AI text and these books are earning significant 💰💸 and most importantly, crowding out sales of non-AI books.
FWIW, a book doesn't need to be high quality to have a market impact. It just has to exist in the thousands, which Generative AI enables.

The first mission of the Church is to help people be attentive to the profound questions of life: those concerning our origin and our destiny, as well as those concerning the meaning of love and suffering. The logic of profit at all costs and the manipulation of information risk exerting undue pressure on people to conform to a lifestyle centred on the consumption of material goods, but our hearts are made to look upwards. #GeneralAudience

In an age dominated by technology, in which efficiency and profit often take precedence, it is so important that we continue to cultivate a spirit of contemplation and allow time and space for beauty. Such an attitude will greatly help humanity, especially young people, to discover the ability of art to uplift and reveal the depths of the human spirit and our openness to the divine. Contemplation presents a marvelous opportunity to encounter the God who is Beauty.

In this era of artificial intelligence, it is becoming urgent to distinguish human art from what machines produce. There is an ontological difference, even before an aesthetic one, between art and what a machine can generate through statistical calculation based on millions of images created by others. Algorithms lack the spark of humanity. For this reason, the Church wishes to renew an alliance with artists and cultural institutions to safeguard our humanity.

Singapore's govt dating app runs on a Nobel Prize-winning game theory algorithm 👏
FirstDate uses Gale-Shapley, the 1962 stable marriage algorithm that won the 2012 Economics Nobel and still runs hospital residency matches and kidney exchanges today.
how it works:
1 | your preferences and dealbreakers build a ranked priority list
2 | proposers offer to their top pick. receivers hold their best offer and reject the rest. rejected proposers move down their list. rinse and repeat until locked
3 | the result is mathematically stable: no two people exist who would both prefer each other over their assigned matches. "the app never showed us each other" becomes impossible by design
the UX:
• one match per cycle, zero infinite scroll
• 72-hour decision window
• contact info revealed only on mutual yes
• Singpass-verified, so everyone is exactly who they claim (told my husband I'm annoyed I can't test it. his response: most people sneak onto dating apps, and here you are openly filing a product research request 🤣 )
commercial apps need you to keep swiping but this app is designed to get you off the platform. Singapore built the first dating app whose success metric is deleting its own users 💀
(fun game theory note: Gale-Shapley yields proposer-optimal outcomes - meaning proposers get their best possible stable match, receivers their worst 👀)
public servants aged 21-35 only for now. interesting to see if state-sponsored game theory beats the free market (or rather, all the tinders and hinges out there) 🍿

Ser periodista de investigación no es nada fácil y más cuando siempre se denuncia al que le sobra poder, muchas veces los periodistas nos enfrentamos al acoso judicial, a la violencia digital y a la soledad de tener una verdad, pero todo eso cobra sentido cuando esta sale sin pedir permiso, da un golpe contundente y los deja a todos perplejos. El periodismo siempre. 🙏🏼

Junior scholars: "I feel awkward citing myself"
Senior scholars: "as I cleverly argued (1988; 1991), admirably reiterated (1993; 1995; 1996); and handsomely concluded (2001; 2004; 2007)..."

Solo los quintiles más altos de ingresos en el país, Q4 y Q5, logran tener ingresos superiores a su consumo en la edad pico de ingresos. Y eso que Q4 por una gotica de tiempo. Es decir el único que potencialmente podría ahorrar para sostener su vejez es el Q5.
