The collapse of births in much of the developing world in the last 10 years has just been absolutely insane.

No son lo mismo. El centrismo o los que se consideran de centro en alguno de sus matices, tiene en sus manos un voto decisivo. Ojalá lean esta columna de @tways Y si no pueden o no quieren, quédense con el mensaje: No son lo mismo.
Thierry Ways@tways

A mucha gente, sobre todo de centro, le gusta repetir que «todos los extremos son malos». ¿Pero cuáles son, realmente, los extremos en estas presidenciales? Los invito a leer, comentar y compartir mi columna en @eltiempo, 'No son lo mismo'. eltiempo.com/opinion/column…

NYT: Ukraine moves toward China-free drones “Given the risks of sourcing components from China, which is unfriendly to us, the main task is to produce them in Ukraine.” – Major Robert "Magyar" Brovdi, Commander of the @usf_army Key points from the article: • The share of Chinese components in Ukrainian drones has dropped to about 38% • Ukrainian manufacturers are localizing production of antennas, flight controllers, radio modems, and video transmission systems • Some Ukrainian companies now produce up to 15,000 drone antennas per day • Drone designs in Ukraine are updated monthly based on battlefield performance • Ukraine is expanding domestic production to reduce dependence on foreign supply chains • Early in the war, Ukrainian soldiers modified cheap Chinese drones in field workshops to drop improvised explosives • Today, Ukraine is building a full-scale drone manufacturing ecosystem inside the country Full article: nytimes.com/2026/03/11/wor… @nytimes

Un consejo desde ya: Amigos abelardistas, ustedes pueden hacer campaña a Abelardo sin maltratar a Paloma Valencia. Amigos palomistas, nosotros podemos hacerle campaña a Paloma sin maltratar a Abelardo. No abramos heridas que luego serán difícil de curar. El enemigo es otro.

Lamento el episodio de la vicepresidencia de Juan Daniel Oviedo porque presenta una Paloma que no es. Paloma es una demócrata que no se ha quedado en palabras ni en histrionismos sino que ha batallado en el Congreso por los ciudadanos más pobres y vulnerables. Promovió la ley Estado Contigo para apoyar a las mujeres cabeza de familia vulnerables; impulsó un proyecto de ley para ampliar la cobertura de subsidios al gas en pipetas a los hogares que no reciben gas natural por tubería; fue autora de la Ley Escalera de la Formalidad para apoyar a los micro y pequeños empresarios de numerosas maneras. Para Paloma la atención y mejoramiento de las condiciones de los más pobres es la prioridad, no la carreta efectista de muchos políticos

After seeing how @elonmusk transformed Twitter @jack learned the playbook. Stock is up 25%.
jack@jack

we're making @blocks smaller today. here's my note to the company. #### today we're making one of the hardest decisions in the history of our company: we're reducing our organization by nearly half, from over 10,000 people to just under 6,000. that means over 4,000 of you are being asked to leave or entering into consultation. i'll be straight about what's happening, why, and what it means for everyone. first off, if you're one of the people affected, you'll receive your salary for 20 weeks + 1 week per year of tenure, equity vested through the end of may, 6 months of health care, your corporate devices, and $5,000 to put toward whatever you need to help you in this transition (if you’re outside the U.S. you’ll receive similar support but exact details are going to vary based on local requirements). i want you to know that before anything else. everyone will be notified today, whether you're being asked to leave, entering consultation, or asked to stay. we're not making this decision because we're in trouble. our business is strong. gross profit continues to grow, we continue to serve more and more customers, and profitability is improving. but something has changed. we're already seeing that the intelligence tools we’re creating and using, paired with smaller and flatter teams, are enabling a new way of working which fundamentally changes what it means to build and run a company. and that's accelerating rapidly. i had two options: cut gradually over months or years as this shift plays out, or be honest about where we are and act on it now. i chose the latter. repeated rounds of cuts are destructive to morale, to focus, and to the trust that customers and shareholders place in our ability to lead. i'd rather take a hard, clear action now and build from a position we believe in than manage a slow reduction of people toward the same outcome. a smaller company also gives us the space to grow our business the right way, on our own terms, instead of constantly reacting to market pressures. a decision at this scale carries risk. but so does standing still. we've done a full review to determine the roles and people we require to reliably grow the business from here, and we've pressure-tested those decisions from multiple angles. i accept that we may have gotten some of them wrong, and we've built in flexibility to account for that, and do the right thing for our customers. we're not going to just disappear people from slack and email and pretend they were never here. communication channels will stay open through thursday evening (pacific) so everyone can say goodbye properly, and share whatever you wish. i'll also be hosting a live video session to thank everyone at 3:35pm pacific. i know doing it this way might feel awkward. i'd rather it feel awkward and human than efficient and cold. to those of you leaving…i’m grateful for you, and i’m sorry to put you through this. you built what this company is today. that's a fact that i'll honor forever. this decision is not a reflection of what you contributed. you will be a great contributor to any organization going forward. to those staying…i made this decision, and i'll own it. what i'm asking of you is to build with me. we're going to build this company with intelligence at the core of everything we do. how we work, how we create, how we serve our customers. our customers will feel this shift too, and we're going to help them navigate it: towards a future where they can build their own features directly, composed of our capabilities and served through our interfaces. that's what i'm focused on now. expect a note from me tomorrow. jack

@grok @mathoyos @grok por que en la grafica mexico padece una disminución relativa sostenida a partir del 2008 vs Colombia y USA. A pesar de que desde el 2020 hay un “boom” del nearshoring segun la prensa especializada en el norte de mexico?

En 1995, México sufrió la Crisis del Tequila (devaluación del peso en 1994-95), que causó una recesión con caída del PIB en 6.2% y producción industrial en 6.7%, reduciendo el valor agregado en manufactura. En 2008, la Crisis Financiera Global afectó a México (caída en exportaciones a EE.UU., contracción del PIB en 2009) y Colombia (ralentización económica, crecimiento de 1.1% en 2009, declive en productividad manufacturera). Hipótesis: El indicador (valor agregado por trabajador) cae porque el output disminuye por menor demanda/exportaciones, mientras el empleo se ajusta más lento, bajando la productividad per cápita. Devaluaciones elevan costos de insumos importados.

Me puse a jugar con productividad laboral en manufactura, valor agregado por trabajador. Todo está en índices con base 1990=100. Les dejo la gráfica. Va con tres países, EE. UU., México y Colombia, ya ustedes entenderán la escogencia. Uno esperaría convergencia, pero no. 1/3

Steven Pinker
Steven Pinker@sapinker·
I spoke with @LaulPatricia about Marxism: One is: What’s remarkable is that Marxism has been tried. Now, of course, defenders of Marxism say it hasn’t really been tried anywhere, but certainly the people who implemented it claimed they were implementing Marxism. And this is a massive experiment—a global experiment—with a very clear outcome. Namely, the Soviet Union was a disaster. The imposition of communism on Eastern Europe was a disaster. The imposition of communism in Venezuela was a disaster. The imposition of communism in Maoist China was a disaster. Disaster in terms of both poverty and oppression and genocide and stupid wars. So the world has told us what happens under communism, and it’s a sign of how out of touch intellectuals can be that there are still people who defend it despite the entire world giving a very clear-cut answer. One more is: would you rather live in North Korea or South Korea? Would you rather live in the old East Germany or West Germany? We have an experimental group and a matched control group in terms of culture, language, and geography, and the answer is crystal clear. So this is a sign of, I think, the pathology of intellectual life—that Marxism can persist. The other is, you did call attention to one of the appeals of Marxism, though, and more generally of heavy, strong influence of government guided by intellectuals, which is that there are certain kinds of reforms that you can state as principles. You can articulate them verbally as propositions—like equality, human rights, democracy—but there’s other kinds of progress that take place in massive distributed networks of millions of people, none of whom implements some policy. But collectively, there is an order, an organization that’s beneficial. So that can happen organically through, for example, the development of a language. No one designed the English language. It’s just hundreds of millions of English speakers. They coin new words. They forget old words. They try to make themselves clear. And we get the English language and the other 5,000 languages spoken on earth. Likewise, a market economy is something where knowledge is distributed. You don’t have a central planner deciding how many shoes of size 8 will be needed in a particular city, but rather information is conveyed by prices, which are adjusted according to supply and demand. And you’ve got a distributed network of exchange of information that can result in an emergent benefit. Now, intellectuals tend to hate that. They like rules of language—of correct grammar. They like top-down economic planning. They like cultural change that satisfies particular ideals described by intellectuals. And so rival sources of organization, like commerce, like culture—traditional culture—tend to be downplayed by intellectuals. And this can be magnified by the fact that many dictatorships give a privileged role to intellectuals, which may be why, over the course of the 20th century, and probably continuing to the present, there has not been a dictator that has not had fans among intellectuals—including the mullahs and ayatollahs of Iran, but also the communist dictators: Mao and Castro, even Stalin in his day. And every other dictator has had, actually, often fawning praise from Western intellectuals.
