Whether you’ve just heard the term “ChatGPT” for the first time or you’ve watched someone else use it and wondered how they make it look so easy—this is the book that finally puts the power of AI in your hands, without the jargon, without the overwhelm, and without needing a tech background. ChatGPT for Absolute Beginners is your friendly, no-nonsense introduction to one of the most powerful digital tools available today.

Have you ever talked to a voice assistant on your phone, seen a computer program beat a world champion at a game, or watched a car drive itself? These moments may feel like glimpses into a science fiction future, but they’re not fiction. They’re examples of Artificial Intelligence—AI—in action. While AI feels modern and futuristic, the journey that brought us to these wonders has unfolded for much longer than most people realise. AI may seem like a buzzword that exploded recently, but the core ideas behind it have fascinated thinkers for centuries.

Artificial intelligence is no longer confined to science fiction—it’s part of our everyday lives. From smartphone assistants and Netflix recommendations to medical diagnostics and fraud detection, AI is already transforming how we live, work, and connect. But what exactly is AI? How does it work? Can it think like us, or even replace us? And what does it mean for our future?

Artificial intelligence, or AI, is a phrase we hear so often that it can feel everywhere—on television, in news articles, buzzing in tech headlines, and even woven into the apps and devices we use daily. AI is now a regular part of modern life, from chatbots on customer service websites to intelligent assistants in your home. But what exactly is AI? Is it about creating super-intelligent robots like in science fiction movies? Does it mean computers that think just like humans? Or is it something much simpler—and far more useful?

Is the world around us real—or is it a construct, a mirage generated by a powerful and incomprehensibly advanced intelligence? This question, once confined to the pages of science fiction novels and speculative late-night discussions, has in recent years migrated into the heart of contemporary philosophical and scientific inquiry. The idea that our universe might be an elaborate simulation, running on an immense computational substrate, is no longer dismissed as a fringe hypothesis. Instead, it is now taken seriously by physicists, cosmologists, computer scientists, and philosophers alike.

What if everything you've ever known—every thought, every emotion, every moment—was part of a simulation? Once dismissed as science fiction, the Simulation Hypothesis has surged into mainstream discussion, embraced by philosophers, physicists, and tech visionaries alike. As computing power soars and virtual realities grow more immersive, the idea that our universe might itself be a simulation becomes less absurd—and more plausible. But if we are in a simulation, the next question is both thrilling and unsettling: Who—or what—is running it? And why?

Have you ever chatted with a computer that seemed to really get you? Asked it a question and, seconds later, it gave you an answer that was actually useful—or even surprisingly insightful? If you’ve had that experience recently, there’s a good chance you were talking to ChatGPT. It might feel a bit like science fiction—an artificial intelligence that can hold a conversation, write emails, draft stories, explain complex topics, and even tell you a joke or two. But ChatGPT isn’t a futuristic fantasy anymore.
