The key technologies of the 20th century - ammonia synthesis, the atomic bomb, punch-tag machining and the computer program ELIZA - have shaped the world today with their solutions and problems. The exhibition shows through the stories of their four protagonists - Fritz Haber, Robert Oppenheimer, Thomas J. Watson and Joseph Weizenbaum - that the rapid development of so-called artificial intelligence raises urgent questions that resonate with the problems of previous technologies. The exhibition presents facts, contemporary and contemporary opinions and historical documents together with artworks by the exhibition's author Jaroslav Anděl. The central thesis of the exhibition is that power and technology are intertwined. It is possible to learn from the stories of four powerful technologies and their protagonists if we are not to repeat their tragic course. They show that decisions about the development and use of technology can have far-reaching consequences that are not necessarily always positive. This means that we should not only try to anticipate what these decisions may bring us, but also ask who is making the decisions, who they represent and who they are accountable to.
