From the early 20th century, flying car has become the symbol of a certain idea of the future, stimulating both science-fiction and technological experimentation. Despite its symbolic value, fueled by fiction, futurism, or cinematography, it has never become part of our lives, not because its technology is too advanced for our current knowledge, but because its costs (in terms of production, consumption, and adaptability) would not outweigh the benefits it would bring to us. The flying car serves as a reason to reflect on how symbolic imagination conditions the way we attempt to construct and imagine our future, often in a dysfunctional, naive, or unproductive manner. The technological flop of flying cars seems to resurface today in the stubborn attempts to reproduce robots with anthropomorphic features. Cyborgs, equipped with legs and arms, are not as functional as mechanical and hydraulic pumps, and the human’s physical structure is certainly not considered by scientists to be the most functional one existing. So why do we persist in trying to build them? Are we driven by the need for the post-human to resemble us? Do we have an unconscious fear of being replaced and therefore objectify ourselves? Or do we simply want to play at being God? By blending the philosophical reflection and semiotic perspective on technology with concrete case studies and analyses of their technical characteristics, this contribute critically inquire on the means by which the efficiency and meaningfulness of these technologies is achieved.
