1 Bit-knowledge. Communication and memory in the machine age Edmondo Grassi “It is difficult to live among people because silence is so difficult” (F. Nietzsche, Thus Spoke Zarathustra) Introduction Access to the digital world without borders, the endless possibilities of connection, knowledge constantly online, human relationships defined by ticks of the fingertips on a screen are really elements of freedom? Or it is a sale of its closeness to enjoy steady and ephemeral visibility in a world devoid of tangibility? How this progress is influencing the person's mind and its memory? We are approaching the deconstruction of the border between real and virtual? There are two worlds, one natural, the other artificially created human being, in which we immerse ourselves more and more, almost with the same regularity and frequency, where, at least for now, is the only sleeping and dreaming space to halt the merger / clash. This duality is increasingly developing a necessary debate on the progress of digital device products and their distribution, which have radically changed our daily habits, our perception of body image, identity, private and of others, particularly with regard to the operations performed by our mind and the knowledge we have and from which we draw to create, produce and evolve: the modification of the act of remembering and the value of personal memory. The hypothesis of this paper, inserted in a first stage of studies of a wider research project, is to understand how the confluence of several phenomena of progress of digital technologies (augmented reality, robotics engineering, big data, Internet of Things) it has been imposed, silently and passively, as a new knowledge convergence basin, which from an actual production process is becoming increasingly virtual and digital; how the memory and language have always been represented fundamental elements of human and himself of his feelings, his most intimate and emotional, but they are facing the loss of their privacy, when exposed to each virtual space ; the importance of the relationship of the mind, conceived as a huge garage which keep what sets us apart as unique individuals, and from which to draw in the path of our existence, which defines our system of reason and the way we operate to study the and understand our reality, but we are replacing hardware or cloud memories, huge intangible containers for big data, to which we refer to task to record what we consider important, weakening, therefore, our brains. The field of investigation may be limited, in this case, in three technology-digital environments that are able to show invisible aspects, but under the gaze of all: - Digital communication by contemporary devices, social networks and big data, tools through which, our every pressure on the screen, each personal sharing, every thought, every image, memory or feeling that we store in the electronic and digital memories contribute the growth of information, big data, of each individual, showing transparently, without filters and exceptionality, fears, desires, fragility and violence: the intimacy, without anything that could differentiate it from ' else but the volume of stored data; - augmented reality, seen as a survey area in which to observe the process of hybridization between natural and synthetic, between the concreteness of the tangible and the volatility inherent in the digitalization of the world. We are immersed in a society where change, progress and knowledge have become synonymous, where our view of reality is
