That's one of the most interesting and depressing parts of post-WW2 architecture (it's present in certain "high culture" architecture before, but not as ubiquitous). It seems narcissistic, entirely focused on what the architect thought would look cool, and completely detached from the individuals who would actually be using the space.
There's a Ludwig Mies van der Rohe building near hear, and the usage of space is simply terrible. It's only a few stories tall, and you have to either wait a long time for the slow and unpleasant elevators to arrive, or rummage around several sets of doors behind them to find the hidden stairs. There's another "urban renewal project" nearby designed by I.M. Pei, and it's a huge deadzone in the middle of a bustling area. It feels almost like finding a dead city from a Lovecraft story - you have these empty huge expanses of concrete that seem much too large for humans. Places where people would congregate, like retail, is deliberately placed underground and away from the road, making the whole area feel abandoned.
Say what you will about modern architecture, but I find it much more pleasant than the stuff that was coming out post-war.
