La agencia francesa Afp pide ayuda dado que hasta sus colaboradoras en Gaza están muriéndose de hambre. Dice en su comunicado que han perdido muchos informadores desde su creación en 1944 “pero nunca habíamos visto morir a uno de hambre”. #periodismo
Very grateful to @Noahpinion for sharing my London talk and using my slide deck to highlight key demographic challenges for the coming decades. I’m a strong believer in open science: academics should share slides, papers, and materials openly to foster honest, rational debate.…
This was my most "big-think" post in a while: A vision of what humanity will look like over the next century, as our numbers steadily dwindle but we're connected ever more tightly into AI-guided hive minds. noahpinion.blog/p/the-dawn-of-…
Must-read discussion of China’s push for industrial automation with Prof. Sun Zhongwei. A few highlights: - China’s push for automation was due to labor shortage, not the cause of it. Workers don’t want factory jobs, prefer pay and conditions at service jobs. Factories were…
El vehículo eléctrico avanza más rápido en Asia, Latam e incluso África que en muchos países occidentales. Aquí la mafia fósil se nos ha hecho fuerte 🤬
The Prime Minister must act with immediate airdrops of much-needed aid into Gaza and get other countries to do the same. It is simply inhumane that Gaza faces starvation due to Israel’s aid blockade. Words alone won’t save lives.
La lógica es clara. 1) La suma hoy no da. 2) Quien crea que le va a ir mejor con un gobierno de PP y VOX vergüenza le debería dar basar su proyecto en el sufrimiento de la gente. 3) El independentismo y el soberanismo de izquierdas ha reclamado históricamente una izquierda…
Nos ahorraríamos mucho inútil y vividor si los diputados cobraran, por ley, lo mismo que ganaban de media los cinco años previos a entrar en política.

Llevo años explicando a mis alumnos que se deben preocupar cuando la gente se vaya. Si quieren venir es que hay oportunidades!
Siento escalofríos.
If you measure primary energy correctly, you’ll realize that human civilization is already almost entirely solar powered. 18 TW of “primary energy” is a rounding error on the 12,000 TW of sunlight that powers our agriculture, to say nothing of the photosynthesis that maintains…
Primary energy is wrong, but not how you think. Primary energy gets criticized because it doesn’t take into account the losses that occur when converting and delivering energy. This makes fossil fuels look like they do more work than they really do because most of that energy…
Sunlight is *by far* the cheapest source of primary energy on Earth. That’s why we use it for farming. Photovoltaics have now made solar the cheapest source of electricity. Few understand the implications of this.

Yes. Writing is not a second thing that happens after thinking. The act of writing is an act of thinking. Writing *is* thinking. Students, academics, and anyone else who outsources their writing to LLMs will find their screens full of words and their minds emptied of thought.
Sobre los charlatanes que “recurren al salvataje de las tres pes: el populismo, la polarización, la posverdad”. Muy buena entrevista de @LadyAAmado a @MoisesNaim: lanacion.com.ar/ideas/moises-n…

Acabo de terminarme este libro. Y aunque habla de los EEUU sobre todo, en realidad nos interpela a todos. Las señales están. ¿Sabremos evitar la faccionalización y a los emprendedores étnicos?
