We reached the point (some time ago) where the save icon being a floppy disk makes absolutely no sense to anyone born after a certain time. We could choose a more modern media format and use an icon of that instead, but we would run into the same problem once that media becomes obsolete.
What is a good icon for the function of saving something that can easily be understood by anyone regardless of language or the march of time?
Edit: I know it’s not really an answerable question and is hard but the question is what would you come up with if tasks to design an icon. Given the constraints of the question, what are your best shots at coming up with something that fills the requirements and why do you thing it would work?
For long term (1000 years) I think an open drawer is best especially with an arrow. It suggests putting something in, loading can be the inverse
So people used to store stuff in physical space like drawers? You mean if they needed something they had to physically go there and get it out of something else? Man, early humans were crazy.
