La polémica por Persépolis pone en evidencia el problema de cierta izquierda: está dispuesta a aliarse, justificar y defender un extremismo ultrarreligioso, que en condiciones normales consideraría intolerable, para "ganar" absurdos debates en redes sociales, contra los "fachas".

[Cinemateca Uruguaya @CinematecaURU]

Enorme tristeza por la muerte de Marjane Satrapi, historietista y directora franco-iraní autora de la inmensamente influyente novela gráfica "Persépolis", que luego llevó al cine. En Cinemateca estrenamos también esa locura llamada "La banda de las Jotas". Satrapi fue, además, una vocal defensora de los derechos de las mujeres iraníes y de sus luchas, a las que la obra de Marjane seguramente seguirá inspirando siempre. 💔

A 22-year-old graduate student in Kazakhstan got so angry at journal paywalls in 2011 that she built a pirate website holding 88 million scientific papers, and last month she turned the whole thing into an AI that lets you ask one question and get the actual research as the answer.

Her name is Alexandra Elbakyan, and the website is called Sci-Hub.

The AI she just launched is called Sci-Bot. It lives at https://t.co/6w0IBtOEYB and almost nobody outside academia knows it exists yet.

Here is the story, because it is one of the strangest things to happen in science publishing in the last 50 years.

Elbakyan was born in Almaty in 1988, the year the Soviet Union started to collapse. She taught herself programming at 12. She read Soviet science books that explained things her family used to call miracles. She got into computer security at university and graduated in 2009 with a degree she barely needed because by then she was already a serious hacker.

Alexandra moved to Moscow that fall. Then Germany. Then a research internship in the United States. She was working on brain-computer interfaces, the kind of research that requires you to read hundreds of papers a year just to keep up with the field.

And every single one of those papers was locked behind a journal paywall that cost between 30 and 50 dollars to read once.

She did the math. A graduate student in Kazakhstan could not afford to read science.

The first thing she did was learn how to get around the paywalls one paper at a time. She passed the trick around to other students. They asked her for papers constantly. She got tired of doing it manually.

So in September 2011, in three days, she wrote a script that automated the whole thing. A user pastes a DOI. The script logs in through a donated institutional credential. The paper comes back free. The website caches it.

The next person who asks for that paper gets it instantly because the previous request already saved a copy.

That was Sci-Hub. Three days of code. One graduate student. Done.

15 years later, the cache holds 88 million scientific papers. Almost every piece of scholarly literature published before 2020 is sitting on her servers. Researchers in 190 countries use it. Studies in Nature have shown that roughly half of all academic paper downloads worldwide now go through Sci-Hub, not the publishers who actually own the copyrights.

Elsevier sued her in 2015 and won a 15 million dollar judgment. She did not pay. The American Chemical Society sued her and won an injunction. She did not comply. Courts in India, France, Russia, and the UK have tried to block the domain. She just moves it. https://t.co/3sAWJzNe8I. https://t.co/tGIETesZ8i. https://t.co/H5WQ1f9lqR. The site has had over 20 domains and is still up.

Nature put her on its list of the 10 people who mattered most to science in 2016. The New York Times compared her to Edward Snowden. The Verge called her the pirate queen of science.

She has not been to the United States in over a decade because she would be arrested at the airport.

The Sci-Bot launch in April 2026 is the part that nobody is talking about.

She took the 88 million paper database and put a small language model on top of it. You ask a question in plain English. The model searches the entire shadow library, pulls the relevant papers, synthesizes an answer grounded in real citations, and links you to the full text of every source. Free. No login. No institutional credential. No paywall.

Three real scientists tested it for a Chemical and Engineering News article last month. They asked it medical and chemistry questions. The radiologist said the answer he got was usable. The chemist said the gaps in recent literature were obvious but the older science was solid. The publisher community is furious.

What she built is what the paid academic AI tools are trying to build. Except the paid ones are limited to what their parent publisher legally owns. Hers is limited to almost nothing.

Alexandra still lives somewhere in Russia. She does not give her address. She does not do video interviews. She gives talks over Skype with the camera off. She runs the largest illegal library in human history from a laptop and a donation page.

A graduate student who could not afford to read science built the system the entire scientific community now quietly depends on.

The publishers have spent a decade trying to shut her down.

She just shipped an AI that makes their entire business model outdated.

Para un país del ingreso de Uruguay, el deterioro de Montevideo es inaceptable y penoso. Estoy en un país con menos de la mitad del PIB per cápita de Uruguay y no veo eso.

La causa no es misteriosa: el presupuesto departamental está atrapado en un equilibrio clientelar-corporativo. Gran parte se va en remuneraciones y funcionamiento, mientras la inversión queda relegada.

Las corporaciones capturan buena parte de la renta y operan con baja productividad. Pero la culpa no es (solo) del chancho; si la ciudadanía reelige sin castigar desempeño, los gobernantes no tienen incentivos para ordenar el gasto, exigir productividad y priorizar inversión.

Así, Montevideo queda presa de la trampa del triángulo de la decadencia (corporaciones, gestión y votantes): alto gasto, bajo resultado y poca rendición de cuentas.

El ciberataque a TuID no debería tratarse como una filtración más y la prensa no parece haberle dado la relevancia que merece. (Sale 🧵)

1/7 TuID no es una web cualquiera. Es la plataforma que verifica tu identidad digital y te permite firmar documentos con valor jurídico. Es, en la práctica, tu identidad en el mundo digital del Estado.
Y lo que pasó ahí todavía no tiene una explicación clara. (Sigue)👇
