I think the ideal is when programs are accessible to novices but at the same time provide instruction to those who care to pay attention and hone their skills. For instance, in Excel, when a user uses their mouse to highlight some cells and create a formula, the formula they created with their mouse is shown in the formula entry form, demonstrating to the user how they might have accomplished the same using their keyboard. This introduces users to 'power user' workflows or tools, while not imposing complexity on the users who aren't interested in learning [at that moment.]
Meanwhile, it's not clear to me how a novice is meant to figure out 'three-finger-swipe-to-undo' on iOS but apparently iOS is the poster-child for intuitive friendly design...
