This paper investigates the influence of scientific and sci–fi narratives when constructing the meaning of hybrid realities, meant as spaces where human–machine interaction is not only a technical matter, but also a cultural and semiotic apparatus. Drawing on a theoretical framework that bridges classical semiotic traditions with contemporary sociosemiotic ones, and with sociological perspectives on symbolic interaction, this paper explores discourses engendered by science — from Turing’s AI to contemporary chatbots — and sci–fi — especially films like Her, Automata, and Ghost in the Shell. The analysis reveals to what extent these discourses contribute to shaping collective imaginaries which range from fascination to apprehension, highlighting the function of narratives as a means of veridiction and ideologisation of technology. As such, science and sci–fi do not merely describe or imagine human–machine interaction but rather concur in constructing the interpretative frameworks within which this interaction is perceived, discussed, and practised. Hybrid realities thus emerge not as given realities, but as discursive effects that define the shared experience of technology and orient the social and cultural practices related to artificial intelligence.
