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.

¿Y la fiscalía sí investiga a Andrea Ramírez, jefe dd María Alejandra Benavides, quien desde hace varios gobiernos es conocida por tramitar desde @MinHacienda los cupos indicativos de los congresistas?
#Nación | Exclusivo: a juicio congresistas de la Comisión de Crédito Público que habrían cambiado votos por millonarios contratos en la UNGRD. Esta es la decisión de la Corte Suprema

Esto es de la mayor importancia. Transparentar la regionalización del presupuesto en el Congreso es el primer peso para frenar el robo del erario y para acabar con la opacidad presupuestal que impide la adecuada planeación y la eficiencia en el gasto.
#ATENCIÓN | El Gobierno radicó el proyecto de acto legislativo “antimermelada”. El ministro del Interior, Rodrigo Lara, explicó que la propuesta crea un registro público de los proyectos que pidan los congresistas, reglamenta el lobby y los conflictos de interés de los legisladores. Tendrá mensaje de urgencia.

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.
Hoy es un gran momento para estudiar filosofía, teología o humanidades.
This is deeply disturbing:
Anthropic secretly invited religious leaders to SF to advise them on AI safety, had them sign NDAs, but then primarily tried to convince them Claude has a soul & moral standing, all while wining & dining them to the max. 1/ tinyurl.com/preview/296b5z8z

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) 🍿
