In this episode of the podcast, I talk to Thore Husfeldt about the impact of GPT on education. Thore is a Professor of Computer Science at the IT University of Copehagen, where he specialises in pretty technical algorithm-related research. He is also affiliated with Lund University in Sweden. Beyond his technical work, Thore is interested in ideas at the intersection of computer science, philosophy and educational theory. In our conversation, Thore outlines four models of what a university education is for, and considers how GPT disrupts these models. We then talk, in particular, about the 'signalling' theory of higher education and how technologies like GPT undercut the value of certain signals, and thereby undercut some forms of assessment. Since I am an educator, I really enjoyed this conversation, but I firmly believe there is much food for thought in it for everyone.
