@victorhck The save icon should be a diskette precisely because the people who grew up without ever using a diskette, now see it as the international symbol for "save file."

It's perfect iconography, unmarred by overly precise or vague metaphors. Today it literally just means "save file" and those old enough to remember using floppy disks can just enjoy the joke.

The down arrow tends to mean "download" which is appropriate if the file is being... downloaded. A floppy with a down arrow is an interesting compromise for "save." But it still suggests the data is changing devices.
