I won't argue with your city of the past argument as I'm not sure I'd term it as the dominant architecture of a city of the future, but I think it definitely has a place. I would argue against Brutalism expressing domination over people - I've always seen it more as expressing function in form, which would be the opposite. Given it's close ties to Soviet architecture I can see how a lot of the buildings built in the style would have literally been used for the oppression of individual will, however.
Also, with regards to it's opinion in the UK and worldwide, Brutalism is experiencing something of a revival:
