In the intricate complex of historical processes in the second half of the 20th century, one of the most crucial is the scientific-technological revolution. It is going on in socialist and capitalist countries and is beginning to take hold in the countries of the Third World; it is thus acquiring a global character. The scientific-technological revolution itself is a profound, qualitative revolution in the forces of production — in this lies its importance. It offers possibilities for a radical transformation of the methods of production, creating advanced instruments of production, incorporating new principles, advanced materials, it brings new industries to life and makes possible a previously unheard of increase in efficiency in all aspects of production.

The current revolution in technology signifies a profound transformation both in the instruments and other technical means of labour and in the methods of managing and organising the process of production and even in the objects of labour. Consequently, it is necessary to think of the technological revolution in the broadest sense of the term — as a revolution in the very elements of the productive forces.

The revolution in science is a dialectical negation of all the previous and essentially mechanistic views of the world. The process of revolutionary transformation encompasses almost all the natural sciences. Their paradigms, i.e., the established, basic premises, canons and conceptions that yesterday seemed certain today reveal their shortcomings and limitations and are being rapidly replaced with new paradigms.

One of the most important results of Marxist research on the problem of the technological revolution is the conclusion that it is impossible to restrict the modern technological revolution to scientific or technological progress. To the extent that science becomes a productive force, the universal education of people, the development of the creative forces of every man, becomes a crucial parameter in the development of the material base of civilisation and all the more becomes an inseparable component and an independent factor in the growth of the forces of production.
