Seminar on Applied Category Theory

On Tuesday June 6, 2023, David Corfield ran a one-day Seminar on Applied Category Theory. He started with a quick introduction to applied category theory for philosophers! Then Toby St Clere Smith spoke about categorical cybernetics and the Bayesian brain. Then I gave a gentle introduction to applied category theory—more about the history of the subject, what people are trying to do, and my own personal involvement than any actual math.
