MIT published a brutally honest report on what AI is doing to students. A committee of professors and students spent five months studying how AI changed learning on campus, and the findings read like a warning to every university on the planet. Study groups are disappearing. Office hours are emptying out. Problem sets and take-home exams no longer prove anything, because AI can produce credible solutions to almost any written assignment in the undergraduate curriculum. Students who lean on chatbots lose mastery and confidence, and some slip into what the report calls cognitive surrender, reaching for AI at the first hint of struggle. The numbers are rough. 46 percent of surveyed MIT undergrads use LLMs daily. 90 percent worry about their own overreliance. Undergrads who feel AI makes them replaceable now outnumber those who feel it makes them capable. The committee's answer surprised me. They refused to fight AI with surveillance. The report calls AI detectors unreliable, says lockdown browsers feel like spying, and warns that policing students builds a classroom atmosphere of mutual distrust. Instead, MIT wants to rebuild education around the things AI can't replace. That means oral exams, semester portfolios, in-person project work, and a required social component in every subject. The report even floats the idea of rethinking grades entirely, since without a GPA to optimize, much of the incentive to cheat with AI evaporates. The committee warns professors against replacing undergrad research assistants with AI agents just because they're cheaper, because a university exists to grow people, not output. The most famous tech school on earth admitted the machines broke its way of teaching. Its answer is more humans, not more software.

Spanish PM Pedro Sánchez: Starting next week, my government will implement the following actions: First, we will change the law in Spain to hold platform executives legally accountable for many infringements taking place on their sites. Second, we will turn algorithmic manipulation and amplification of illegal content into a new criminal offense. Third, we will implement a hate and polarization footprint system to track, quantify, and expose how digital platforms fuel division and amplify hate. Fourth, Spain will ban access to social media for minors under the age of 16. Platforms will be required to implement effective age verification systems — not just checkboxes, but real barriers that work. Fifth and last, my government will work with our public prosecutor to investigate and pursue the infringement committed by Grok, TikTok, and Instagram.

Timezones aren’t a problem, mindset is. Remote work forces asynchronous thinking, which often produces better decisions.

Me parece tan ridículo que lo único que puedan pensar, incluso bajo el miedo, es en hacerse rico... Tenemos un problema serio de mentalidad que nos está destruyendo
Me parece el artículo del fin de semana. En Silicon Valley ya no se habla de “revolución tecnológica”, se habla de supervivencia: la IA como la última oportunidad para hacerse rico antes de que las máquinas se queden con el trabajo, el dinero y el futuro. El miedo es brutal: una élite tecnológica con riqueza infinita… y el resto atrapado en una clase permanente de perdedores. Con Musk avisando de “malestar social” y el hype disparado por las futuras salidas a bolsa de gigantes de IA, el mensaje que corre por San Francisco es uno solo: “hazte rico ahora o no te salvarás después”. Y mientras tanto, la vivienda se prepara para otro golpe… porque cuando llegue la nueva ola de millonarios, el puente se levanta y el que se queda fuera, se queda fuera para siempre. O ahora o nunca lo serás. Os dejo el enlace. Es brutal. wsj.com/tech/ai/why-the-tech…

I wonder if this came next with a whole AI Strategy proposal. Here I see intentions and direction (and naming a couple of promoter/champions). What about values guiding it, capacity building initiatives from the company (not just shifting the training fully on employees), etc
If you think @Sentry isn't serious about AI, I'd recommend reading @zeeg's latest internal email about it

LO QUE NADIE TE CUENTA Este niño tiene un sarcoma osteogénico. Un tumor que te come el hueso. Hace 40 años: amputación directa. Hoy: le quitamos el trozo y ponemos hueso de cadáver. ¿Eso es nuevo? NO. Lleva haciéndose desde que yo no había nacido. ¿Entonces qué cambia? Que ahora antes de abrir hacemos un ensayo general con un muñeco de plástico. Útil, sí. Revolucionario, para nada. LA NOTICIA REAL (que no vende) Para salvar esa pierna necesitas: 3 cirujanos especializados 1 anestesista pediátrico al menos 2 enfermeras 1 circulante Quirófano CERO prisa CERO mirada al beneficio ¿Qué hospital privado puede permitirse esto? NINGUNO. Porque no es rentable dedicar medio equipo toda una mañana a un crío. EL PROBLEMA Nos venden "tecnología futurista" cuando lo revolucionario es otra cosa: que tengamos un sistema que puede gastarse recursos infinitos en salvar la rodilla de un niño sin preguntar cuánto cuesta. Eso NO lo hace una impresora. RESUMEN: Gran cirugía. Equipazo. Resultado perfecto. Pero dejad de vendernos la impresora 3D como si fuera el protagonista. El protagonista es un sistema público que puede hacer Tetris con huesos reales durante 8 horas sin mirar el reloj. Viva la sanidad pública. Que es la única lo suficientemente loca para invertir todo eso en salvar UNA pierna.

All my new code will be closed-source from now on. I've contributed millions of lines of carefully written OSS code over the past decade, spent thousands of hours helping other people. If you want to use my libraries (1M+ downloads/month) in the future, you have to pay. I made good money funneling people through my OSS and being recognized as expert in several fields. This was entirely based on HUMANS knowing and seeing me by USING and INTERACTING with my code. No humans will ever read my docs again when coding agents do it in seconds. Nobody will even know it's me who built it. Look at Tailwind: 75 million downloads/month, more popular than ever, revenue down 80%, docs traffic down 40%, 75% of engineering team laid off. Someone submitted a PR to add LLM-optimized docs and Wathan had to decline - optimizing for agents accelerates his business's death. He's being asked to build the infrastructure for his own obsolescence. Two of the most common OSS business models: - Open Core: Give away the library, sell premium once you reach critical mass (Tailwind UI, Prisma Accelerate, Supabase Cloud...) - Expertise Moat: Be THE expert in your library - consulting gigs, speaking, higher salary Tailwind just proved the first one is dying. Agents bypass the documentation funnel. They don't see your premium tier. Every project relying on docs-to-premium conversion will face the same pressure: Prisma, Drizzle, MikroORM, Strapi, and many more. The core insight: OSS monetization was always about attention. Human eyeballs on your docs, brand, expertise. That attention has literally moved into attention layers. Your docs trained the models that now make visiting you unnecessary. Human attention paid. Artificial attention doesn't. Some OSS will keep going - wealthy devs doing it for fun or education. That's not a system, that's charity. Most popular OSS runs on economic incentives. Destroy them, they stop playing. Why go closed-source? When the monetization funnel is broken, you move payment to the only point that still exists: access. OSS gave away access hoping to monetize attention downstream. Agents broke downstream. Closed-source gates access directly. The final irony: OSS trained the models now killing it. We built our own replacement. My prediction: a new marketplace emerges, built for agents. Want your agent to use Tailwind? Prisma? Pay per access. Libraries become APIs with meters. The old model: free code -> human attention -> monetization. The new model: pay at the gate or your agent doesn't get in.

I'm Boris and I created Claude Code. Lots of people have asked how I use Claude Code, so I wanted to show off my setup a bit. My setup might be surprisingly vanilla! Claude Code works great out of the box, so I personally don't customize it much. There is no one correct way to use Claude Code: we intentionally build it in a way that you can use it, customize it, and hack it however you like. Each person on the Claude Code team uses it very differently. So, here goes.
