Ted Chan's largest work to date is to a certain extent devoted to the search for ways to create AI (Artificial Intelligence) - Artificial Intelligence. But, probably, to an even greater extent it is dedicated to people working with AI carriers, digitants - digital entities who, dressed in cute avatars, develop and learn on special “planets” platforms, where they can, having mastered human speech, communicate as if they were their creators, and with each other. The author, who himself works in the computer industry, accurately and often ruthlessly depicts the problems that exist in it, technical (such as incompatibility of platforms, which the average user faces today), and human: the emergence of new - albeit virtual creatures (digitants) entails problems of an ethical nature. Many, having bought funny pets, begin to understand that there is plenty of hassle with them (training, the need to play together) and... often put them to sleep. That is, they simply turn it off, convincing themselves that they are doing this for a while. The developers, having endowed the digitants with a robotic body, that is, by loading the AI digitants into the robot body, thereby introduce them into our real world, which entails a whole series discoveries and problems, including such as the proposal to use "embodied" digitants as sexual partners. Conflicts that arise between people - even loving people - arise because Antoine de Saint-Exupéry so clearly expressed: “You are forever in responsible for everyone he has tamed.” This short story by Chan raises an unusually large range of problems: conceptual (the author’s approach to the problem of AI is both original and deep), technological, ethical. This book is as much about digital entities as it is about us.
