Modern machines are so insanely fast, the UI should almost react before you do an action.

My 5900X machine with relatively slow RAM running CachyOS actually almost feels as instant as DOS machines with incredible low latency.

Instead, we get tons of layers of abstraction (Electron etc), combined with endpoint security software in the enterprise world that bring any machine to its knees by inspecting every I/O action.

Zed is an awesome editor where every interaction is just “snappy”.

I feel all the animations and transitions have been introduced to macOS just to paper over slowness. I’ve disabled them via the accessibility settings which helps in perceived snappiness a bit, but it also makes yank visible where performance is not up to par.
