I work in UI in enterprise, where slight color shade differences between releases can cause uproar. I cannot imagine the thought process behind liquid glass in any sense.

OSX's Aqua was also an insanely bold UI with a lot of gimmicks, but was still usable for the most part. I'm so very curious about the internal discussions around this.

It was a different time, too. I remember being starstruck after seeing the UI. Windows looked overwhelmingly grey in comparison.
