Well, that's why there is a lot of complaints.

The main selling point of a macbook is not a UI with transparency. It's hardware stuff (like ARM processors, battery life, aluminum frames, etc..) and a decent, stable, unix-ish software environment. No one is using macOS for the visual effects, so it is annoying that Apple is revamping the UI everyone is used to in order to add more visual effects.

Seems nuts to me, but I'll be curious to see how this all pans out.
