> Could you sit in front of Blender, Microsoft Office, GIMP or Photoshop without previous knowledge of them and do anything at all with them?

yes

they have menus, especially GIMP, the ugliest of them all, but menus are everywhere just a right click away

but anyway you are in a familiar zone: every software is made that way, except, of course, Apple.

the problem with Apple is that they are trying to make every software look like a calendar or contact list application.

that's a pretty low bar for a standard UI and frankly it means they consider their users mentally challenged.
