Seriously. As a user I can count on zero hands the number of times I’ve said “Oh great, I’m sure glad this UI is animated!” - and likewise zero times have I missed it when animation isn’t used. Animation is a way to light small units of your users’ precious time on fire, for zero benefit.

As the other user alluded to, Animations are not actually there for people who are comfortable using a computer. The vast majority of users are borderlines in capable of using the internet these days. Animations are supposed to be there to really help guide these users into understanding what the scary machine is doing when they click it. Can they be overused, absolutely, but i think have an accordion fold out animated is a reasonable case. You gotta remember your average user isnt paying any fucking attention, so drawing their attention to important changes on screen is not only good but necessary. I'd prefer no animations ever, but i also dont own an iphone while the majority of the world either does or wants to.

That's the positive interpretation, but none of the discussions I've had with UI designers or managers have been about adding animation for accessibility, and the zeitgeist of the last decade has been that skeuomorphism (of which intuitive animations are a subset) is passé.

So far as I can tell, all that the stakeholders want from the UI, animations included, is pizzazz.

If it is for those people who barely grasp the slightest thing about what’s going on on-screen, I could grant them that, if they’d let me turn it off. In the days before jailbreak became basically impossible, setting the animation duration to zero was a blessed, incredibly satisfying thing. It’s exactly what I want. Just do the transition in zero seconds.

My iPhone 15 can’t even catch my first 1-2 keystrokes on the keyboard, multiple times a day, but boy howdy does it have the time and the cycles to animate that f*%ker into view. The disrespect for my time and my needs is so obvious.

Animations are also a way to explain causal relationships between interactions and their results, and to help build mental models of software behaviour.

Being related to neither software behavior nor the structure of the underlying problem, animations tend to obscure the causal relationships and make it harder for user to build a correct mental model.

I see where you're coming from: animations are overused and even when they make sense they are made too slow and flashy (because otherwise how would the implementors feel like they did something if it's barely noticeable?)

Animations are like bass in music: most people notice them only when they're missing or bad.
