"In Relationships 5.0, Elyakim Kislev guides the reader on a journey through world historical contexts of technological evolution and the innovations that came from those historic situational necessities. This book provides an important perspective, predicting an uncertain future where we must carefully consider how we design and depend on AI. It helps us realize that AI is not just a tool created in response to our needs for survival or a desire for entertainment, but also a projection of our own humanity." -- Julie Carpenter, Research Fellow, Ethics and Emerging Sciences Group

"Relationships 5.0 is a timely and readable survey of what the latest technologies mean for sex and personal relationships. The author steps back from the headlines and takes us on an ambitious journey through human history to consider the really big, interesting questions about how our relationship to technology is changing, as well as our relationships with each other. If someone wants a Fodor's guide to the next fifty years of sex and love, this book may be it." -- Neil McArthur, Director, Center for Professional and Applied Ethics, University of Manitoba

"At last! A compelling book that takes a historical approach and discusses the challenging topic of emotional companionship, AI, VR and robots. This book is a must-have for anyone interested in relationships and, in particular, relationships with technologies." -- Wendy Moyle, Program Director, Menzies Health Institute Queensland, Griffith University

"Readers of this book will not only learn the very long history of technological influences on human relationships, including communities and families, but also several critical issues about bonds between humans and highly advanced technologies such as AI, VR, and robots in near future." -- Tatsuya Nomura, Professor, Faculty of Advanced Science and Technology, Ryukoku University
