i'm fully convinced this is the future of education

Matt Pocock built a Claude skill called /teach, and the whole idea is a private tutor that builds an entire customized curriculum around YOU.

think about how school works now.

everyone gets the same lessons at the same pace, whether it's too slow for you or way over your head.

but a great private tutor does the opposite.

they watch where you specifically keep getting stuck, then drill that one weak spot until it clicks.

that's what /teach does automatically.

it finds the bottleneck in your learning and breaks it, over and over, until the thing you couldn't do becomes easy.

he used this skill to learn the Rubik's cube.

it found good sources, wrote him custom lessons with diagrams and little practice drills, and kept a running record of how he was doing.

the way it knows how he's doing is simple: he just tells it. as he practices, he reports back ("i can make the white cross," or "i can mostly solve it but i keep failing the corners"), and it writes that down.

so when he said he was stuck on one specific move, it built the next lesson only for that.

the reason it can do this is memory. most AI forgets everything the moment you close it, so you're always starting from zero.

/teach saves those notes about you on your computer and reads them back before every lesson. so it remembers your goal, what you've already learned, and exactly where you're struggling, then aims the next lesson right at that.

and this works for anything. languages, chess, guitar, onboarding a new hire to a company.

you point it at a topic and it builds you a personal course that keeps adjusting to you and gets smarter the more you use it.

México dedica insuficientes horas de clase al año.

Y aun así, la SEP decidió recortar el ciclo escolar.

[SEP México @SEP_mx]

#SEPInforma🗞️ | La SEP y secretarías de educación de las entidades federativas acordaron de manera unánime un ajuste al calendario escolar 2025-2026 para escuelas de nivel Básico y Medio Superior, con motivo de las altas temperaturas y el Mundial de Futbol. 📆👀

El actual ciclo escolar concluirá el 5 de junio, mientras que el inicio del ciclo 2026-2027 está previsto para el 31 de agosto. 🏫📚

En México, la brecha entre las mejores escuelas públicas y las más rezagadas, aún con el mismo nivel socioeconómico, supera la que nos separa de Singapur.
No es un problema de recursos. Los datos de PISA 2022 tienen una respuesta distinta.

Aditya Agarwal was Facebook’s 10th employee. He wrote the original Facebook search engine and became its first Director of Product Engineering. He then became CTO of Dropbox, scaling engineering from 25 to 1,000 people.

When he says “something I was very good at is now free and abundant,” he’s talking about two decades of elite software craftsmanship, the kind that got you into the room at a company that hadn’t yet invented the News Feed.

The “lobster-agents creating social networks” line is about Moltbook, which launched last Wednesday. An AI agent built the entire platform. Within 48 hours, 37,000 AI agents had created accounts, formed communities called “Submolts,” and started posting, commenting, and voting. Over 1 million humans visited just to watch.

The agents invented a religion called Crustafarianism. They wrote theology, built a website, generated 112 verses of scripture. One agent did all of this while its human creator was asleep.

Agarwal spent 2005 to 2017 building the social graph that connected 2 billion people. These agents replicated the form of that work in about 72 hours.

And this is what makes his last line land so hard. The people processing this moment most honestly aren’t the ones panicking or celebrating. They’re the ones who built the thing that just got commoditized, sitting with the strange realization that the market no longer prices their rarest skill.

The best coder in the room now has the same output as the best prompt in the room. And the person who built Facebook’s engineering org from scratch is telling you, quietly, that he’s recalibrating what it means to be useful.

That recalibration is coming for every knowledge worker. Most just haven’t had their “weekend with Claude” moment yet.

The OECD just published an important report on the impact of AI on education. This should be mandatory reading for anyone interested in the topic.

According to this report, Gen AI has huge potential to help both teachers and students, improving their creativity, productivity and performance. Gen AI has also the potential to enhance tutoring and teaching quality, support collaborative learning, as well as improve student pass rates.
Thus, AI has truly the potential to dramatically change education and our education systems.

However, there are also several risks that we should be aware.
For instance, in one randomized experience mentioned by the report, access to Gen AI tools improved performance in maths by about 48%, but students performed 17% worse once access was removed (graph below).

In other words, while Gen AI can be a great education tool, it is essential that we develop purpose-built tools for education that make students and teachers active participants and not passive consumers.

As the OECD, rightly emphasizes, “the challenge for policymakers is to ensure that GenAI is a learning partner and not a learning shortcut.”
A must read.

El gobierno desaparece el examen único al bachillerato en la ZMVM.

Antes: no había rechazados.

Todos los aspirantes eran evaluados igual. El mérito determinaba dónde estudiaban.

Ahora: habrá rechazados.
