Doing a quick survey of the apps on my machine, it seems like most have just forgone the button altogether. For those that still have the button, the floppy icon seems to still be there.
Yeah, purely from memory here but it's not that the save icon went out of fashion, but the concept of an icon bar or ribbon has gone; Microsoft's current UI standard for their native apps still has a ribbon IIRC, but I feel like that's one of the last vestiges. Using real world analogies went out the window after skeuomorphic design was no longer a thing too.
Oddly enough, for me I had trouble adjusting to the 'folder' icon (or referring to folders as folders), we grew up with the term "directory" and I never had an association with anything physical with that.
