I think the ultimate value is in them staying the same: iow, they are learned.
I like the style of this one, and as "save" it's generally ok ("save as" is even great once you know save, though not sure about languages not using ellipsis).
I presume the floppy icon is comparable: Visually distinguished from all other icons, so a good icon even if the shape lost its actual meaning
For the save icon I agree. This "new" icon has to be learned just like the floppy disk already has to be. Nothing about it intuitively tells me what it means. It actually looks similar to the log-in glyphicon that for example bootstrap is using: https://getbootstrap.com/docs/3.3/components/
There is nothing wrong with the floppy and no, people are not too stupid to learn that it means save.
Taken to an extreme icons can morph from hieroglyphic symbols to alphabetic characters to the point where it can be hard to see what the original object modeled was.
