Though I agree that skeuomorphs are generally concrete rather than abstract representations, ignoring the obsolescence aspect means that almost any design element that looks like a concrete object (however stylized it may be) would then be a skeuomorph, right?

Your camera app icon that looks like a camera lens - skeuomorph? I’d say no because cameras still have lenses.

When you use your camera app and your phone speaker plays a sound that mimics an SLR shutter clicking even though your phone’s camera doesn’t use a shutter curtain - skeuomorph? Yes, it mimics something familiar from a previous design no longer necessary in the current design.

I am a bit of a word nerd and recognize that words can change in meaning over time, but I’ve always understood skeuomorph to be in line with my usage. Can anyone point me to an alternate definition?

I asked this question on this post on a different instance, but would there be issues being that the code compares a float to integer zero “0”?

Honest question - what about these are skeuomorphic? I mean, I know that the Save button icon being a floppy disk is skeuomorphic because we don’t save our files on floppies anymore, but what about these are no longer necessary to the concept?

Here’s a fun CGP Grey video on the matter: https://youtu.be/pUF5esTscZI?si=9czdx4u8jWruZoui
