This book, GPT-4 Speaks Out... On Global Warming, Climate Change & Itself, continues the dialogue between the author and GPT-4, in the set GPT-4 Speaks Out... which seeks to introduce the reader to summaries of the foremost Global Catastrophic Risks. Perhaps because of Greta Thunberg's spirited personal public campaign, many more people are aware of the problem of climate change, but this book aims to introduce various different questions on the subject, with the intent that it will enable diplomats, politicians and the public to have further insights into how to deal with it all. In particular, the author's introduction is repeated in all of this set of books, not only because of its educational importance to enable the necessary transformation to happen, but also because repetition is an important way to shift beliefs. Please keep reading it all: it may just change your life and the world. The questioning dialogue with GPT-4 continues to be a delight for the author; it wanders intuitively, rather than logically, around the subject of Global Catatrophic Risks and ends up examining GPT-4 on its own views of its own self-awareness and consciousness. One key aim of this book is to introduce readers to this extraordinarily powerful artificial intelligence and what it can do, in its both smartness and its errors, so that the reader can gain a deep glimpse into the rapid developments of AI racing towards a new future.
