The presentation argues that the design and system development approaches articulated through the Dialogue Seminar (“Dialogseminariet”), including their philosophical underpinnings, are only more relevant in today’s AI landscape. The Dialogue Seminar was a collaboration between the Royal Dramatic Theater, Center for Working Life and KTH Royal Institute of Technology, all in Sweden, from circa 1985 onwards (which can be broadly characterized as human-centered, participatory, and non-rationalist. It makes the argument that the specific manner in which the labor, knowledge, and skills of the human was articulated in relation to technology in general and AI in particular in the Dialogue Seminar holds the power to productively inform our current challenges in deciding what agency is, where it should lie, and why it matters. In making this argument, the presentation specifically turns to the concept of error. Errors and mistakes, it is argued, were employed by the Seminar – in lectures, syllabi, books, articles, conference proceedings – to demonstrate the unique nature of human capabilities; we fail, as it were, intelligently, as opposed to the rigidness of machines that err predictably, but also incoherently which is a testament to the profound difference in quality between ourselves and our tools. The talk shows that such “error studies” are highly useful in scrutinizing the alleged faculties and capacities of generative AI.
