Historically, design as a priority worsened UI for average and new users, and Apple has prioritized a feeling of elegance over ease of use.

Liquid glass puts UI second (feature cues) in favor of UX (interesting experience), harkening back to skeuomorphism but misprioritizing UI. I appreciated in Jobs's time how skeuomorphism was used to reveal more features, and give new users simple cues.

Now there is this idea that there is a higher percentage of advanced users, but since now there are MORE users (anyone with a screen), and continual change, I think there is still a large percentage of less advanced users "harmed" by prioritizing UX over UI.
