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?

The truth is, AI isn’t just about robots, science fiction, or futuristic fantasies. It’s about machines—computers, software, systems—that can perform tasks we usually associate with human intelligence. These tasks include recognising your voice when you talk to your phone, recommending a movie you might like, spotting patterns in data, or even diagnosing diseases from medical images. And while the technology behind it is complex, the concept at its heart is surprisingly straightforward: AI is about teaching machines to do bright things.

And here’s the good news: understanding AI doesn’t require a background in coding, engineering, or data science. It doesn’t even require you to be a tech-savvy person. All it takes is a bit of curiosity and a willingness to explore. In this book, we’ll do exactly that. Together, we’ll take a jargon-free journey into the world of artificial intelligence—what it is, how it works, and why it matters.

One of the biggest challenges with AI is that it often sounds more complicated than it is. That’s partly because the field contains buzzwords: machine learning, neural networks, deep learning, and natural language processing.
