>im not a UX expert by any means but my first impression at WWDC seeing liquid glass was "holy shit, they pulled that off? i know apple would never compromise on legibility, so... how? there are so many situations where this won't work, and they can't exactly control the content that the buttons are overlaid on top of"

That's what I mean, even if worded badly. Someone probably managed the glass distortion effects as an experiment, or demoed a transparent redesign of a small portion of the UI, and it looked awesome. I think it's cool that they can green light weird ideas, otherwise there's stagnation. But it is obvious that there were fundamental unresolved issues, and yet something in the process pushed the idea forward anyway.

It signals something very wrong in company structure. If you can't trust the process to drop what doesn't work, then trying new things is risky. And as you say, it's an experiment that feels so unlike apple, to disregard polish and accessibility that way.
