IMO animation is only useful in certain cases like notifications and smooth scrolling. If the user is the one initiating an interaction though, there's usually no need to animate anything (opening a menu, for example) because he/she is already expecting something to happen Edit: s/animation/transitions/g

Just as an example, if I were to trigger Mission Control [1] in macOS without animations, it would be pretty jarring. In this case, I control the speed of animation with the speed of my mouse gesture, and it's quick enough not to get in my way, but animated enough so that I have a sense of continuity between my full screen web browser and the view of all windows on that desktop.
In contrast, the default minimize/restore animations in macOS are too long and cutesy for me.
