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?
Or pretty much anywhere in the manufacturing sector.
Plenty of products you use on a daily basis, especially processed foods, are being cranked out on equipment controlled by PLC’s from the 1980’s or earlier.
