Ok. Today we have multi-Ghz processors, with multiple cores at that.
Photons travel about 1 foot per nanosecond ... so the CPU can executes MANY instructions between the time photons leave your screen, and the time they reach your eyes.
Now, on Windows start Word (on a Mac start Writer) ... come on ... I'll wait.
Still with me? Don't blame the SSD and reload it again from the cache.
Weep.
Not sure where you're getting at. MS Word, full load to ready state after macOS reboot takes ~ 2 seconds on my M1 mac. If I close and re-open it (so it's on fs cache) is takes about ~1 second.
You, and sibling comment author just never experienced the truly responsive ui.
It is one where reaction is under a single frame from action. EDIT: and frame is 1/60s, that is 16.(6)ms. I feel bad feeling I have to mention this basic fact.
This was possible on 1980s hardware. I witnessed that, I used that. Why is it not possible now?
Base model M4 Mac Mini -- takes 2 seconds to load Word (and ready to type) without it being cached. Less than 1 second if I quit it completely, and launch again, which I assume is because it's cached in RAM.
