Really, color is such a great way to convey information.
How many years have to elapse before that icon is rethought? When was the last time you personally held an actual floppy disk? How would you even fit a floppy disk into a phone (or website)?

The save icon may be anachronistic, but a hardware drive is still an accurate representation of what's happening. Today's phones are about as much about phoning as computers are about word processing.
I don't think any of that matters.
How many smartphones run on AA batteries [1]? How many people have ever configured anything involving gearing [2]?
Rethinking an icon feels like a contradiction. It doesn't matter what it's 'supposed' to be.
It's not a floppy disk, it's the save icon.
Personally I think that the floppy disk is a good icon precisely because it has ceased to be an everyday physical object. Today, the outline of a 3.5" disk simply means "save" -- there's no other valid association for this shape any more.
That is the original definition of an icon: an image that transcends its apparent meaning. Orthodox Christian icons were certainly representational, but the presence of holiness was communicated by a commonly understood system of signs that went beyond the level of appearances.
A more modern example of an icon in this sense could be Andy Warhol's images of Marilyn Monroe: calling them "silk-screened reproductions of the portrait of an actress" doesn't capture anything about their cultural meaning.
I can see the animation principles (for instance) being applied from a smartwatch, all the way through 4K displays.
Since most of the points aren't just "declared good" but come with justification, it would be trivial to try to rebuff them, rather than dismiss them with a general argument.
Edit: I'm talking about the spec rather than the actual icons. The icons themselves are scalable as well.
