What do you mean? In this model "memory" (as in, the ability to remember things you have learned, seen, thought, or otherwise experienced) is emergent from the ability to form new pattern recognizers... The ability to form new pattern recognizers is not itself built on this "memory".

Do you mean that you are questioning the ability to form new pattern detectors? Do you think that isn't done, or do you just think the mechanism behind how that happens is inadequately explained?
