It's a weird turn of event that OS X stayed a much more classic os than what Windows 8 was becoming. I remember that for a long time OS X was wasting less screen estate than Windows 8 and all that mix that was Windows 10.

But since Big Sure it means that it got even worse than what It was with the first version of OS X. I remember how crazy it was it setup a mac emulator, set it's resolution to my mac's resolution, full screen mode, and see how much space you could have with classic Mac OS, it's just crazy and everything remains legible.

Suddenly the windows desktop metaphor makes more sense because you can actually have many windows next to each other. OS X has almost always tried to diverge from than, that lead to great things like exposé, spaces and then mission control but it looks like they never considered to reduce elements size.
