And while I agree that ornamentation is very likely lost to cost savings, the switch to glass walls is also just a huge improvement for people inside the building.
Having worked in an all-glass tower and also a "normal" office building, my personal experience is that the natural light that giant windows let in and the external views that they afford are both phenomenal improvements to the atmosphere. It's really a much more pleasant environment to work in. The only catch is that the interior or window treatment design needs to consider glare from sunlight directly hitting computer screens and/or eyes.
So, sure, maybe something something costs, but people also pay attention to environmental ergonomics now in ways that they never used to.
