AI (AGI) is here and it is already having an impact on education, and on society at large. In this100-page book, we explore in detail the capabilities and the weaknesses of AI as a language or writing assistant. We might think of AI as a tool now, but it will become an environment, an integral part of our studying and working life. The changes to educational institutions will be revolutionary, more transformative than the introduction of computers and the internet. To prepare for that, we need to understand what AI can and cannot do. We have to play our part as creative humans with our own identity and voice so that we can interact efficiently with AI assistants to become better and more productive writers. In the book, we also consider the ethical uses of AI and how we adapt, as teachers and students, to this new environment.
