> You obviously know how the UI state changed because you're the one who requested the change.

We must be using different devices because mine often fail to register my intent and in that case the failure to animate is often the only signal I have (that doesn't take more than a few seconds to register)

I use keyboard and mouse. Unlike touchscreens, these always work reliably.

And if you're using animations as indications of correctly functioning hardware, why not just use useful work as the indication instead?

Useful work takes longer to do than the animation that indicates the work has been queued.

		None of the animations described in the article are of this type. Opening a text input area or changing desktop should be instant on all modern hardware. If you genuinely have something that can't be accomplished within one frame it's acceptable to display a progress bar, but I don't consider progress bars to be a "UI animations".
