Since his earliest books, Attali foresaw and announced signals of the future, albeit weak at the time, that later came true: In "La parole et l'outil" (1976), he announced and described the shift from an energy-based society to an information-based society. In "Bruits", in 1977, he announced what would later be the internet, YouTube, and the importance of musical practice; in "La nouvelle économie française", in 1978, he discussed the coming emergence of the personal computer, hyper-surveillance and self-surveillance. In "Les trois mondes", in 1980, he announced the shift of the centre of power around the Pacific. In "L'ordre Cannibale", in 1980, he announced the advent of a prosthetic society, now known as transhumanism. In "Histoires du temps", he announced the rapid pace of history and the growing immediacy of relationships. In "Amours", he announced the emergence of poly-romantic relationships. In "Au propre et au figuré", he announced the break-up of property and its use, and subsequently he invented the concept of the "nomadic object." In "Lignes d'horizons", in 1990, he predicted the relative decline of US power. In "Brève histoire de l'avenir", he announced a corporate power grab by health data and insurance companies. In "L'homme nomade", he described the great movement of populations whose sedentary life was only a temporary stage.
