Generation n-2: This is our save icon. It's for saving a file to a floppy disc.
Generation n-1: I don't use floppy discs anymore, I only save files to my hard drive, but I remember floppy discs, so the iconography still works for me.
Generation n: Why is that the save icon?
Generation n-1: Because people used to save files to floppy discs, then later to hard drives, but the icon stuck around. That's a 3 1/2 inch floppy disc, which actually isn't really floppy. There was a 5 1/4" disc which was floppy, but no one uses that as the save icon.
Generation n: Why not update the icon? How about something like one of these instead?
Generation n+1: What does it mean to save a file? Why do we even need that function. I just update my files in Google Docs or Quip, they are always up-to-date.
Generation n+2: What are files?
