using memex possibly replaces memory with Google effect (knowing where to look for information vs knowing the information)
using spaced repetition might be a solution to this, but I'm curious if the better solution would be just dropping memex and spaced repetition altogether, to force myself to remember things
this feels loosely related to extended mind and memex with the idea that our external thinking tools are somehow encoded within us, and evolve with us, but watch out since each extension is an amputation
