To begin with, what to call a new productive class? We have already mentioned a few names - the "knowledge worker" or "knowledgeable employee" Peter Drucker , "the creative class" Richard Florida , my own clumsy "Demiurge". What to choose? At the time, a Danish-Dutch researcher Johan Huizinga  published a book Homo Ludens, in which he proposed to use this name instead of the Homo Sapiens proving that the game is a key attribute of the human being, laid down on the level of instincts. Later in the story Strugatsky "The Time Wanderers" describes a new breed of people, which is derived from evolved Homo Sapiens. They are called Homo Ludens, which means "man playing" . Or just lyudeny. Although Huizinga theory and amusing, unfortunately, the majority of homo sapiens as soon as it becomes older, not up to the games. They even learn once, you need to produce food for the family. But a new class will have to learn all his life, and as a proven crowd of researchers, training - is the main feature of the game. So that they too will have to play life. Therefore, further in this book we have this new "creative" class and will be called - lyudeny.
