We shall have so saved it, that the succeeding millions of free happy people, the world over, shall rise up, and call us blessed, to the latest generations.”

“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”

—Hannah Arendt (1906–1975)
