It looks to me like Andy and Michael are grasping at recreating with modern technology and tools what many (most? all?) indigenous cultures around the world used to ritually learn and memorize their culture's knowledge. Mnemonics, spaced repetition, graded initiation, orality, dance, and song were all used as a cohesive whole to do this.
The best introduction to many of these methods and their pedagogic uses is best described by Lynne Kelly's book Knowledge and Power in Prehistoric Societies: Orality, Memory, and the Transmission of Culture.
If they take her ideas as a basis and then layer on their own thinking, I think they'll get much further much quicker. Based on my reading of their work thus far, they're limiting themselves.
