This lecture was given on March 12, 2018, at the Graduate Center of The City University of New York, during a session of the New York City Category Theory Seminar directed by Pr Noson S. Yanofsky, whom I warmly thank for the invitation.
The reception of the participants was great, I keep a very good memory of this meeting !
N.B. : the last part of the lecture, about dynamics and interactivity, is extracted from a presentation given at the NIST (Gaithersburg, MD) on March 15, 2018, during a workshop on Applied Theory Category organized by Spencer Breiner.
Here are the slides (be patient, the slides may take a little time to load...) :
