Can a Machine Think?

Artificial intelligence is already all around us. It recommends videos, recognises faces, answers questions, creates pictures, translates languages and helps robots move through the physical world. But how can a machine learn? Does a chatbot understand what it says? Why can AI sound completely confident while giving an answer that is completely wrong? Can a Machine Think? takes curious young readers inside the extraordinary world of artificial intelligence. Beginning with the meaning of intelligence itself, it explains algorithms, training data, machine learning, neural networks, chatbots, image generation and robotics in clear and engaging language. Readers will discover how AI finds patterns that humans might miss, why recommendation systems influence what appears on their screens and how synthetic images, voices and deepfakes can make false events look real. They will also explore the difficult questions surrounding privacy, bias, creativity, employment and the possibility of machine consciousness. AI is neither magic nor an independent creature. It is a powerful collection of technologies designed, trained and controlled by people. Its systems can assist doctors, scientists, teachers and engineers, but they can also make mistakes, repeat unfair patterns and be used irresponsibly. Serious, exciting and evidence-based, this book shows young readers what artificial intelligence can do, what it cannot do and why human judgement remains essential. The most important question is not simply whether a machine can think-but whether people will think carefully enough about the machines they create.
