I'm old enough that the first computer I used was an IBM PC. Running PC DOS. Granted, I was very young and only remember it because of the little turtle in Logo. Then it was Apple IIs. Then Windows. I actually used Linux in the 90's. I remember Windows 8, but mainly because of the complainers. I was Linux full time by then anyway.

But I do happen to enjoy having extraneous menus hidden. Why are they cluttering my screen and workspace when I'm using keyboard shortcuts anyway? I want to see my actual work, not some menu I don't need and will never click on...

Using a mouse to click on a bunch of tiny menus littered all over the place is horrible for productivity and screams "boomer"...

Oh! then you've lived well through all these design fads of the last decades. Let me assure you, a bad designer is going to do a bad job whether you give them a desktop-first framework or not, that's the kind of desktop interfaces you might be thinking of. But a mobile-first framework will always render poor results on desktop, regardless (and in spite) of the skill and knowledge of the designer.

I cannot say this based on evidence, but I'll say anyways based on subjective common sense, that the Start Menu of Windows 95, 98, XP, and 7 were all immensely better than the Start ..."screen" thing of Windows 8.
