Wall-free office spaces did not quite work out as desired and therefore cubicles came into being.
The passage explains the original purpose behind the invention of open-plan offices and cubicles. It emphasizes that architects and designers created these spaces to break down social barriers by eliminating physical walls, thereby promoting freedom and flexibility. However, the passage reveals a shift in this utopian vision when companies adopted the design not for its democratic potential but to maximize worker density, effectively turning offices into "white-collar assembly lines." This led to the creation of cubicles in an effort to restore some individuality to the office environment.
