Imagine the poor bastards in the future trying to comprehended the floppy-disk "save" icon.

Those poor bastards are here now. I'm teaching my 7 year old all these strange words and icons. We carry so much historical garbage.

I remember seeing a post like a decade or more ago of someone asking why you click on a little TV to save documents.

Me too! I had assumed that 'radio button' was a bastardization of 'radial button', referring to the very shape which the author notes is conventionally used for them.
