A few of us, myself included, made audible "WTF?” noises.
CDN was a formalism (to be generous) invented by Roger Schank. My own impression was that it was handwavy nonsense with no explanatory or computational utility.
(Side note: I once talked myself out of a job with Schank's group at ILS by inadvertently trashing work done by one of Schank's collaborators, unaware that my interviewer was one of his PhD students. In hindsight, I dodged a major, major bullet).

Anyway, whether CDN was good or bad, the fact was that Minsky did NOT hold Schank in high regard (and vice-versa), so to hear Minsky saying that he thought CDN was a basic knowledge structure in the human brain was a little like hearing the Pope say that this Satan guy made some good points, actually. 5/
