Yep - and that is exactly the point with the arguments around the floppy icon. It doesn’t really matter how it was derived, what physical tech it represents or how outdated that tech now is.
The point is - people associate the floppy icon with the save function because it is so widely used in that capacity.
Many icons are pretty arbitrary when you get down to it. They have just been adopted to have a certain meaning and we continue to use them to this day.
Who decided a cross X should mean close window - but it does and now most programs with windows based interfaces utilise it (including Blender) because everybody understands that what it means.
We could of course decide that the cross isn’t the best representation of the close action and implement something else instead - but to what end? Who would it benefit?
Yes changing the floppy icon to something else isn’t a big deal in the grand scheme and people would get used to it - but why go out of the way specifically to make Blender different to 90%+ of sofware in existence.
I thought the idea was to make Blender more accessible and mainstream - but stuff like this simply makes it appear more niche and inaccessible than it should.
