An interesting concept that was discussed in this section was the concept of cytoplasm. Cytoplasm is what Hofstadter calls the place where "the building and dismantling of temporary, puzzle-specific structures take place". Numbo shares this cytoplasm with Jumbo. Hofstadter said the cytoplasm could be thought of as a "black board" or a "working memory", this sounds very intuitive to me. I would thinking it could also sort of be like a "mind" because all processes occur within it, just like everything humans percieve occurs within their mind.
Numbo is desgned to imitate human cognition during the solving of a Numble problem. It sounds like Numble does a pretty good job in replicating human cognition, it even makes mistakes like a human and will go in wrong directions. I admire Hofstadters pursuit of creating human-level cognition and the fact that he even accounts for the flaws that humans have when solving such problems. I never really thought of how hard it would be to create human-level cognition.
