Yes, that's true, but the style also changed so dramatically, not just means of production. e.g. machine production does not have to mean that overall building proportions became so weirdly unattractive as well. But really, just because it was _cheap_ an _easy_ for a machine, therefore it meant it was _aspirational_, _desirable_ for a human. That is the core shift, it was primarily ideological (and we rationalized this new mindset _after_ it already reified itself).
