Indeed, the present situation is very different from the expansion of mechanization encouraged by the development of machine tools and the steam engine in the nineteenth century. The spread of the "new technologies" (electronics, computers, telecommunications, as well as new synthetic materials and biotechnologies) creates far greater disparities than
