It depends. Ux is related to user's background. In 21th century you are unable to use the first calculators because you have no reference to the https://fr.m.wikipedia.org/wiki/Boulier
Same with displaying a "hard drive" icon. No baby would understand as he would never see it.
So the UX question is :
- what is the knowlege of the target user?
- target that knowledge.
Same choosing the appropriate language to speak to anybody.
@tuxicoman yes. Exactly right, and once one successfully knows what the knowledge of the target user is, a successful UI will usually not _require_ additional explanation for those users (good documentation would still be a best practice but not required for user to be able to begin using it).
