Vannevar Bush's key stroke of genius was identifying that historical systems use rigid alphabetical or numerical indexing (like the Dewey Decimal System), but the human brain works through associative connections based on personalized experience, not alphabetization.

Evidence Quote

historically, we use alphabetical or numerical indexes. Think of a library's Dewey Decimal System or just a dictionary. Right, which is incredibly rigid. Like, if I want to learn about apples, I look under A. But, my brain doesn't naturally move from apples to apricots just because they share a starting letter... The human mind works by association, not by alphabetization.
