In the late Seventies-early Eighties of the 20th century, the diffusion of the PC marked a watershed between the strictly professional use of computers, and their diffusion to a huge public. It represented the democratization of a powerful and remarkable technology, a first stage in a never-ending and pervasive process of independence and freedom of the individuals. This revolution, however, placed in the historical perspective of the last century, proves to be a fundamental step (but still a single step) in the evolution of the users’ digital skills and in the transformation of their experience and life.
