I wouldn't compare Vista to the Liquid Glass UI, that is more akin to the Aqua style interface from years ago. The blur and transparency of Liquid Glass is just the latest trend in UI that is also found in the latest version of Android 16. The only difference there is that they call it Material Design 3.
These trends come and go where we previously saw the skeuomorphic design, followed by the Flat UI. Based on past UI designs, you can expect the next one in about 5 years and you will find some users that don't like that one when it comes out and will say they preferred Liquid Glass. Expect further refinements with updates during that time and feel free to use the Feedback link to let Apple know how you feel.
