When people ask AI a question, it answers the question in a very short time. So, people may feel that AI can think and answer questions as human beings do. Before Alex read this book, he believed this, too. However, this book says it will never happen. Actually, AI only uses a lot of information to get the best answer. So, when it has more information, the answer will be much closer to the perfect one. AI technologies will be cleverer tools for human beings to use. This book also says almost half of our jobs will be done by AI technologies in the near future.
