in a way there are two conversations happening here. eisenman has never made what i would call architecture. he makes giant "modern art." this helps resolve the curiosity that no one really likes giant ugly buildings (eg the parisian domino building) but they've won out. there's a prevailing idea that we need giant works of modern art in cities, either for individuality or whatever else.
as someone on the ssc subreddit pointed out, it's all very well to fundamentally hate piss christ, because you don't have to think about it. but if you drive by soldier field on the way to work every day... (and in case anyone thinks giant functional stadia can't be attractive, at least concede that minute maid, fenway, etc do a better job of fitting in)
interesting links. i think a lot of postwar architecture boils down to an ego trip.
