Actually it was really The Human Use of Human Beings published two years after Cybernetics which was wildly popular, Wiener having rewritten his argument for a 'general audience' - sans all that calculus.

The books anyone invested in intellectual development needed /to show/ they had a copy of, rather than one they exactly made it through cover to cover.
