Un llamamiento inaplazable para poner freno a la carrera hacia la superinteligencia. «Un libro muy interesante, incluso si no estás de acuerdo con su conclusión.» Marta Peirano, periodista y escritor

Un libro imprescindible para desenmascarar las falsas promesas de la inteligencia artificial y entender cómo las grandes tecnológicas convierten su hype en un negocio a costa de nuestras vidas.¿Va a acabar la inteligencia artificial dominando el mundo? ¿Han creado los cientificos una forma de vida artificial capaz de pensar por si misma? ¿Va a quedarse con nuestros puestos de trabajo? ¿Estamos entrando en una era en la que los ordenadores son mejores que los humanos? Las doctoras Emily M. Bender y Alex Hanna responden a todas estas preguntas con un rotundo NO, con frases sarcasticas como Ya les gustaria o simplemente riendose. Estos temores no son mas que una consecuencia de la implacable promocion la IA por parte de las empresas tecnologicas para justificar el robo de datos, motivar la creacion de herramientas de vigilancia en el puesto de trabajo y devaluar la creatividad humana. En La estafa de la IA encontraremos ejemplos reales, argumentos claros y opiniones de expertos que nos proporcionaran las herramientas para detectar el hype de la IA en todas y cada una de sus manifestaciones. Ya que, al descubrir la explotacion que hay detras de su implantacion y la usurpacion de poder que pretende ocultar, seremos capaces de disipar el humo que nos intentan vender, tanto en el trabajo como en nuestra vida cotidiana.

Una reflexión urgente sobre los cambiosque laIA está generando en las estructurasde poder, la creatividad, la guerra,la responsabilidad y el amor.En 2017 Vladimir Putin sentenció: "Quien domine la InteligenciaArtificial, dominara el mundo". Hace ocho años estas palabras podian sonar desmesuradas, pero hoy en dia reflejan una realidad escalofriante. No por nada, hay quienes comparan la carrera por la supremacia en el desarrollo de la Inteligencia Artificial con el proyecto Manhattan, que produjo las primeras armas nucleares. Es una carrera millonaria, en la que participan Estados y empresas privadas, y que cambiara para siempre ya lo esta haciendo la forma como los seres humanossomos gobernados o dominados, la forma como creamos y nos relacionamos con el arte, nuestra concepcion de la responsabilidad, nuestra forma de hacer la guerra, nuestra forma de amar. Este libro aborda con profunda lucidez los desafios que la Inteligencia Artificial plantea en estos ambitos de la vida humana.Aun no sabemos quien dominara la Inteligencia Artificial; lo que si sabemos, advierte Pedro Salazar Ugarte, es que el empuje tecnologico esta impulsando la mayor concentracion de poder en la historia. El podereconomico, el poder politico y el poder ideologico se funden en una peligrosa alianza totalitaria que amenaza las libertades de las personas. Por ello, este libro es tambien un llamado a imaginar maneras de regular el fuego prometeico de laIA, para explotar sus enormes beneficios y mitigar sus numerosos riesgos.

When you accidentally knock over a virtual glass in a modern stealth video game, the resulting noise does not simply play a pre-recorded file. The game engine instantly fires thousands of invisible, mathematical linesaudio raysthat bounce off the digital walls, calculating the exact material density of the carpet, the obstruction of the doorway, and the precise echo delay before the sound reaches the guards ears.This astonishing technological feat is known as Audio Raycasting. For decades, video game audio was a flat, unconvincing illusion. Today, programmers have engineered complex acoustic simulations that mimic the real-world physics of sound propagation. This microscopic calculation of reverb, occlusion, and diffraction is the invisible backbone that makes sneaking through a digital shadow feel terrifyingly real.This technical exploration takes you deep into the code of psychoacoustics. It reveals how audio engineers map virtual geometry not just for the eyes, but for the ears, manipulating frequencies to induce absolute paranoia in the player.Stop looking at the graphics and start listening to the math. This book deconstructs the brilliant auditory illusions that transform a silent line of code into a heart-pounding immersive experience.

There is a hidden tier of competitive gaming where human reflexes are entirely obsolete. In the realm of Tool-Assisted Speedruns (TAS), players do not rely on their hands; they use emulators and code to program a sequence of inputs, advancing the game one microscopic frame at a time.The goal is to push the software to its absolute theoretical limit. By calculating precise memory addresses and exploiting atomic flaws in the collision detection algorithms, TAS creators produce runs that defy the laws of virtual physics. Characters warp through walls, teleport across maps, and complete sprawling eighty-hour adventures in less than five minutes. It is a fusion of rigorous computer science, reverse engineering, and digital art.This deep dive into the TAS community uncovers how obsessive programmers deconstruct our favorite childhood games. It details the painstaking process of manipulating Random Number Generators and the relentless pursuit of shaving fractions of a second off a world record.Discover the ultimate intersection of mathematics and entertainment. This book reveals how the greatest video game performances ever recorded were played entirely by machines instructed by brilliant human minds.

In the earliest days of 3D video games, players navigated blocky corridors and fired weapons blindly, guessing the trajectory of their projectiles based on the center of their screen. This clunky guesswork was eliminated with a seemingly trivial addition: the rendering of a tiny crosshair. This simple visual anchor fundamentally rewired the architecture of digital combat.The introduction of the crosshair shifted the focus of game design from mere survival to absolute precision. It allowed developers to implement hitboxes, recoil spread, and strategic targeting, birthing the modern competitive esports industry. Today, the crosshair is a highly complex piece of dynamic software. It expands to communicate inaccuracy during movement, pulses to confirm a successful hit, and changes color to convey critical environmental data, acting as the ultimate neurological link between the players eye and the game engine."Zeroing In" decodes the evolution of this vital UI element. It explores the psychological satisfaction of the hit-marker and how microscopic changes in pixel placement dictate the competitive viability of billion-dollar gaming franchises.Discover the invisible math behind your digital accuracy. Appreciate the profound impact of minimal UI design, and learn how a handful of pixels completely redefined global gaming culture.

In the early days of computer graphics, rendering natural textures like fire, water, or stone was a computationally overwhelming nightmare. Programmers relied on rigid geometric patterns or pure randomness, resulting in environments that looked artificial, chaotic, and entirely unconvincing. The dream of expansive, organic virtual worlds seemed impossible due to the severe limitations of hardware memory.The breakthrough came in 1983 when Ken Perlin invented an algorithm that generated coherent, pseudo-random noise. This elegant mathematical trick simulated the chaotic yet continuous patterns found in nature, allowing computers to generate infinite clouds, mountains, and textures on the fly without consuming massive amounts of storage. Perlin Noise became the invisible foundational architecture for procedural generation, forever altering the trajectory of video games and digital cinema."Mathematical Landscapes" decodes the brilliance of procedural generation. It explores how a single mathematical function bypassed hardware limitations and empowered developers to build the limitless universes seen in modern role-playing games and simulations.Discover the invisible code that builds your favorite digital realities. Appreciate the intersection of elegant mathematics and creative engineering, and understand how simple algorithmic logic can infinitely scale the boundaries of artistic creation.

In the early days of video games, digital worlds were rigid, pre-animated, and entirely predictable. A falling object didnt actually fall; it merely played a pre-recorded sequence of frames. The illusion of reality shattered the moment a player pushed against the boundaries. Then, a few lines of complex mathematics introduced something revolutionary: actual gravity.Gravity in the Machine chronicles the invention of the physics engine, focusing on the Havok software that permanently rewired interactive entertainment. The book explores the monumental programming challenges of simulating real-world physical forcesmomentum, friction, and collisionin real-time. It reveals how giving objects genuine weight and chaotic mass transformed level design from static obstacle courses into dynamic, unpredictable playgrounds.The narrative delves into the accidental hilarity of ragdoll physics and the psychological joy players experience when a digital environment reacts exactly like the real world, allowing for emergent, unscripted gameplay that the developers never even planned.Readers will gain a deep appreciation for the invisible math that holds virtual universes together. The book demonstrates how introducing systemic rules, rather than hardcoded scripts, is the ultimate secret to building engaging, infinitely creative systems in tech and beyond.

Millions of players log on every day not to embark on epic quests or test their reflexes, but simply to watch a number slowly increase. The rise of idle gaming defies all traditional logic of what makes a video game engaging, yet it is one of the most profitable sectors in the modern mobile economy.Idle games, or "clickers," strip away complex gameplay to expose the raw, underlying architecture of the dopamine feedback loop. By breaking down progression into infinite, mathematically calculated micro-rewards, these games hijack the brains innate desire for accumulation and efficiency. The player is not playing a game; they are managing a spreadsheet that rewards them for their absence, creating a compulsive need to return and harvest their artificial wealth.This book deconstructs the mathematical models and behavioral triggers that make non-interactive games wildly addictive. You will discover how developers balance exponential scaling curves, prestige resets, and offline progress to create an unbreakable cycle of engagement that seamlessly integrates aggressive monetization tactics.Unlock the dark arts of player retention. Analyze the absolute distillation of reward psychology and learn how modern software leverages our biological craving for progress to extract infinite value from minimal interaction.

In the early days of computer graphics, animating a flock of birds or a school of fish was a nightmare. Animators had to manually plot the trajectory of every single creature, resulting in stiff, lifeless movements. True organic motion seemed impossible to replicate with cold codeuntil a computer scientist named Craig Reynolds stopped looking at the flock and started looking at the individual.In 1986, Reynolds invented the "Boids" algorithm. He realized that complex swarm intelligence does not require a central leader or a pre-planned route. By giving each digital entity just three simple mathematical rulesseparation, alignment, and cohesionhe created a system where thousands of independent agents spontaneously formed fluid, hyper-realistic flocks. This emergent behavior revolutionized the digital world. It is the invisible math that powers the terrifying swarms of bats in modern horror games, the massive charging armies in fantasy films, and the organic traffic flow in open-world city builders.This book traces the history of procedural animation and the beauty of emergent complexity. It demystifies the programming logic that allowed software to mimic the unpredictable grace of nature.Readers will grasp how minimal rules can generate monumental complexity, offering profound insights into artificial intelligence, game development, and the mathematical rhythm of the natural world.

When you explore a massive, photorealistic open-world video game, you are experiencing a brilliant optical illusion. Your console or PC does not have the processing power to generate that entire universe at once. In reality, the digital world only exists exactly where you are looking.Frustum culling and occlusion culling are the unsung heroes of 3D graphics engineering. To save critical memory and prevent games from crashing, the rendering engine acts as a ruthless director, constantly calculating your exact field of view (the frustum). Any mountain, enemy, or building that falls outside of this invisible coneor is hidden behind another objectis instantaneously deleted from existence. The moment you turn your camera, the world is hastily rebuilt right before your eyes in a fraction of a millisecond.This technical deep dive exposes the fascinating mathematical trickery that makes modern gaming possible. You will learn how developers utilize bounding boxes, spatial partitioning, and Z-buffers to cheat hardware limitations, ensuring that the machine never wastes a single calculation on something the player cannot see.Peek behind the digital curtain. Discover the paranoid, hyper-efficient architecture of game engines, and understand the beautiful lie that allows vast virtual universes to run seamlessly on a small plastic box in your living room.
