Claims: Game detects “ad whales,” then periodically gives them smooth runs until they barely beat their high scores. Right at that point, it kills them deliberately and offers a revive if they watch an ad. $100 million annually in revenue. Hellish.

If you take the industrial revolution as a take off event. It *200 growth rates. An equivalent set of requirements would seem to be 1. Each person uses less energy 2. There are less people 3. Each generation of tools is more accurate 4. People take less time to train
Ben Horowitz on what it would take to actually see an AI "fast takeoff" scenario, using a framework from Databricks CEO @alighodsi: 1. Each new model needs far fewer GPUs than the last 2. Each new model takes less time to train 3. Each new model is more accurate than the last 4. It keeps happening, again and again "Zero of those four have been met... We're really talking about a risk that's entirely theoretical at this point." @bhorowitz on @theallinpod

Only one of these happened with the industrial revolution. And it is happening this time. Tools did get better but also '3. Each new model is more accurate than the last'

We got far more people taking much longer to train, and living longer. And the people were significanly bigger and used far more power. If the last *200 growth rates had more of us needing more why this one needs less resources all the time?

En julio de 1938, Benito Mussolini tenía preparado un desfile propagandístico para coronar a Gino Bartali como el estandarte atlético del fascismo italiano tras conquistar el Tour de Francia. El dictador exigía que el campeón dedicara el maillot amarillo a la gloria del régimen; Bartali, católico inquebrantable apodado "Gino el Piadoso", se negó en público a hacer el saludo fascista y llevó el ramo de flores directamente al altar de la Virgen en la catedral de Notre-Dame de París. Desde aquel desplante, la policía secreta lo catalogó como una figura incómoda, pero su estatus de ídolo popular obligó al poder a tolerar su presencia. Cinco años después, en septiembre de 1943, la Alemania nazi ocupó el norte de Italia e inició la cacería y deportación sistemática de la población judía. Fue entonces cuando el cardenal de Florencia, Elia Dalla Costa, lo convocó a una reunión a puerta cerrada. La Iglesia y la red clandestina DELASEM ocultaban una imprenta secreta en el convento de San Quirico en Asís, donde falsificaban identidades para cientos de familias en peligro. Solo faltaba un eslabón: alguien con la capacidad pulmonar de devorar montañas en solitario. Bartali solicitó un salvoconducto oficial alegando que debía pedalear cientos de kilómetros para no perder el fondo físico de cara a la posguerra. En jornadas infernales de hasta 380 kilómetros de ida y vuelta sobre carreteras bombardeadas, cruzaba los Apeninos entre Florencia, Asís y Roma. Dentro del tubo del sillín, la tija y el manillar hueco de su bicicleta Legnano de carreras, viajaban enrolladas las fotografías de los refugiados y los pasaportes falsificados que les abrirían la frontera hacia la libertad. Salía a la carretera con su maillot de competición con su apellido bordado en el pecho para que los centinelas lo reconocieran a la distancia. Cuando las patrullas de las SS y las Camisas Negras le ordenaban detenerse en los retenes, Gino se bajaba con frialdad de hielo, les firmaba autógrafos a los soldados y les soltaba una advertencia técnica demoledora: "Por favor, tengan mucho cuidado y no toquen la bicicleta; está calibrada al milímetro para mis carreras. Si mueven las piezas, arruinarán meses de entrenamiento". Intimidados ante la leyenda nacional y temerosos de desajustar una máquina de élite, los guardias se limitaban a registrarle los bolsillos y lo dejaban continuar con decenas de vidas ocultas en el metal. Su compromiso no se detuvo en el asfalto. En Florencia escondió a la familia judía Goldenberg en un sótano de su propiedad en Via del Bandino, alimentándolos en secreto durante los meses más crudos de la guerra. En julio de 1944 fue arrestado por la sanguinaria Banda Carità y conducido a Villa Triste, un cuartel de torturas donde fue interrogado durante tres días bajo amenaza de muerte. No delató a nadie ni dio un solo nombre; las gestiones del cardenal y el pánico de las autoridades a una insurrección popular forzaron su liberación. Gracias a sus viajes, más de 800 personas escaparon de los campos de exterminio. En 1948, con treinta y cuatro años, volvió a ganar el Tour de Francia, pero jamás escribió un libro sobre su pasado bélico ni utilizó su heroísmo para cobrar favores políticos. Cuando su hijo Andrea descubrió su secreto décadas después, Gino le exigió guardar silencio absoluto con una frase lapidaria: "El bien se hace, pero no se dice. Y ciertas medallas se cuelgan en el alma, no en la chaqueta". Murió en el año 2000; trece años después, el memorial de Yad Vashem lo declaró Justo entre las Naciones, confirmando que las piernas que ganaron el Tour pedalearon, sobre todo, para derrotar al horror. #shoa

I cannot let a steam engine analogy go by without bringing up John Wilkinson, perhaps the most underappreciated engineer of the Industrial Revolution. Watt had figured out how to dramatically improve the steam engine, but he spent years struggling to actually manufacture one. The problem was embarrassingly simple: nobody could make a sufficiently round cylinder. The casting and machining tolerances were atrocious. Watt complained that one 18-inch cylinder was out of round by as much as THREE-EIGHTHS OF AN INCH. Steam leaked past the piston. He tried packing the gaps with cork, oiled rags, paper, and apparently even old hats. Nothing worked particularly well. Enter John Wilkinson, a British ironmaster whose immediate concern was manufacturing better cannons. At the time, iron cannons were commonly cast around a core, introducing defects and misalignment that could make the barrels inaccurate or dangerously weak. Wilkinson developed a process for boring cannons from solid castings, and in 1774 patented a vastly improved boring machine. The key innovation was almost comically mechanical: a massive, rigid boring bar, supported at both ends, that could cut a genuinely straight, circular hole instead of following the irregularities of the casting. He adapted this technology to Watt's cylinders. By 1776, Matthew Boulton was boasting that Wilkinson had bored a FIFTY-INCH cylinder accurate to within the thickness of an old shilling. Suddenly, the steam engine was a commercially viable machine. And the story gets better. Wilkinson became one of Watt's first customers, buying an engine to drive the blast machinery at his own ironworks. The steam engine was now helping manufacture the iron that made more steam engines possible. I find this whole episode absolutely extraordinary. The Industrial Revolution was, for a critical period, bottlenecked on the ability to make a sufficiently round hole. We remember Watt, and rightly so. We remember the invention of the steam engine and the subsequent development of thermodynamics. But the man who made the machinery that made the whole thing possible is practically a footnote. I think we consistently underestimate how much of scientific progress is actually downstream of advances in tooling, measurement, and manufacturing precision. It's not just that technology precedes theory. Sometimes the decisive breakthrough is that someone finally figures out how to build the thing the theorists have been talking about for twenty years. Anyway, I think John Wilkinson deserves considerably more credit for modern civilization than he gets.
a few thoughts: 1. pretraining science is kind of like how people built quite good steam engines before they understood thermodynamics. “Science owes more to the steam engine than the steam engine owes to science.”-(L.J. Henderson). if nick is right, which i am pretty sure he is, progress points in the direction of more interpretability, and pretraining was "slouching towards monosemanticity". my guess would be that major breakthroughs in interp also advance capabilities 2. nick is a good friend of mine, safe to say my origin story at openai wouldn't have happened if i hadn't met him, and it's fascinating watching him operate and seeing the early drafts evolve into this. he's the most profoundly happy guy I know- not driven by guilt, activism, or religious terror, but by fascination. he of course understands the stakes of understanding neural networks, but it doesn't seem like the core reason he does it: he just loves the neural nets. afaict he's posting this from some beautiful hideaway in tokyo. there's a lesson in there for all the +EV maxers. i feel very grateful to have met him 3. i do think it's crazy how few people across the world were staring at neural nets growing: most have moved to a different level of behaviorist analysis, thinking about reward functions and test scores and whatnot. it does not bode that well for the major model companies, oai included, that fundamental breakthroughs like this are coming from outside. we've become too much of a pressure cooker focusing on local incentives, studying narrow tracks under old paradigms, mostly doing engineering, rather than fundamental research, and implicitly hoping the next model will figure it out

FT: Isn’t it better for you to make a unilateral declaration that you will not strike Russian refineries, even if Russia continues striking your energy infrastructure, in order to get Trump administration back on side? Zelenskyy: “If such a moment comes and such a deal requires Ukraine not to respond after Russian attacks, the question is when the next deal will be? And with all these deals, maybe the next one will be about gas — definitely it will be gas. Who will get the money? And who will spend this money? And on what? Not to rebuild Ukraine, I think. Not to support us. It will go the opposite way.” First it will be a diesel deal, then a gas deal, then another deal, and another, deal after deal after deal, until Trump and Putin are fully united in the sweet ecstasy of dealmaking. And every single cent of that revenue will go directly toward killing Ukrainians. Americans must stop this madness! Trolls keep telling me they owe us nothing. Fine, give yourselves the gift of not being child-murder funders.

Read this, but think how far Ireland has come in the interim. I was 18, one of my best friends was gay. That was illegal. We are not a perfect country but we are a much better country.
Imagine a brilliant female teacher got sacked because she was in a relationship with an adult male? welcome to 1980s Ireland! In 1982, Eileen Flynn lost her job at the Holy Faith convent secondary school New Ross, Co. Wexford. She hadn't broken any law or been bad to her students. Her sin/crime was falling in love with a "separated" man with children. And as if that wasnt enough, the "harlot" chose to live with him! In Ireland in 1982, that was enough. Divorce was still unconstitutional, and would remain so until a razor-thin referendum in 1995. A separated man, like Eileen Flynns partner Richard Jones, could not remarry. So the school's management decided that a teacher living openly with him was a scandal worthy of dismissing her. Because there wasn't any other Catholic schoolkid related issues worthy of anger at the time... Eileen Flynn courageously fought back, heretic hussy that she was, under the Unfair Dismissals Act. And the Employment Appeals Tribunal sided with the school. When she appealed to the High Court, she lost again in 1985. The judge accepted that a school could protect its religious ethos, and that a teacher's private conduct could be held against her. The good aul days, eh?

The whole world is going electric and we are way behind.
In September, China's combustion vehicle (ICE) sales dropped to just a third of the market for the first time Battery electric vehicles are getting close to half of the market (47.3%), while Plug-ins added another 19.7%. Only 5 years from >90% to 33% ICE.
