I was going to ignore this as a troll comment because computer memory has its antecedents in human memory but the commenter is right - the combination of memory and cache to talk about human memory seems misleading.

I kind of like the association since it speaks to how text collected while browsing the web can be used to generate new text, which is similar, at least metaphorically, to how human memory is reconstructive and transformative, not perfect recall. https://en.wikipedia.org/wiki/Reconstructive_memory
