Stanisław Lem is mostly known as a sci-fi writer and not widely perceived as a visionary of the cyber age, despite the fact that he foresaw the future of information technology better than most scientific experts. Indeed, his visions of future information- based societies have proved to be remarkably accurate. Lem’s stories fuse together elements of fantasy, philosophy, and science, but what we can really learn from them is the nature of humanity, technology, and philosophy, as well as the values of technological prophecies. Moreover, Lem gave birth to, without naming it as such, the concept of philosophy in technology, which is a perspective on technology and philosophy that explores the deep implicit philosophical foundations of technology and humanity.
