Anyway, it's not the point. You're always free to disable animations if you think they're making you slow. I think too many people in the discussions about UIs are confusing quirks of particular interfaces with first principles, and are extrapolating specific experiences to the whole field.
Sadly less and less true nowadays. I always try to turn off any animations. On Android the settings is not respected, not even by Google owns app. On KDE itseld, it respects it pretty well, but applications don't always do, and not consistently. Firefox has its own animation settind on Android, linux, and windows (never tried on mac), and firefox doesn't even respect it in some case when scrolling even though i turned off everything.
I hate animations. I want everything instant, my time is precious, my ability to suffer shit moving all over the place is limited.
That's an irrelevant comparison. If you booked a long flight, would you accept somebody pointlessly delaying it for an hour just because that's short compared to the duration? The correct amount of avoidable latency is zero, regardless of how much unavoidable latency there is.
It's also false; I have a good mouse, good mouse skills, and my taskbar sits against the edge of the screen giving it effectively infinite height (see Fitt's law). I can hit taskbar targets in around 300ms.
