This is a unique book because it was written not by a human, but by an artificial intelligence (AI). It is not just about blockchain technology and Bitcoin, but also about how the AI can fine-tune its explanations to suit an exact age. Each chapter prompts the AI to provide answers that can be understood by a specific age. The book is designed to provide a compilation of repetitive information, tracing a human's life and understanding of complex topics at different ages. As you read, I encourage you to reflect on how you perceived the world at each age and how your understanding has evolved over time. It's important to recognize that as you progress through different stages of life, your ability to comprehend the world changes. Therefore, I hope this book will help you appreciate how your perspective on complex topics and the world at large has evolved and will continue to do so in the future.
