Good design is prescient of an audience, yes. Often, however, good design applies widely to audiences it was never intended for. For instance, OXO brand kitchen supplies were designed to be big and easy to handle for the arthritic. I own a lot of their supplies because they're sturdy and easy to handle. I never use it and think "Wow. I'm feeling arthritic today" Similarly, Apple. Designing to make computing cool and succeeding wildly probably means the design will apply to a large number of unintended audiences as well. If you wear a suit and are professional, a glowing apple is still going to look better than a clunky black box.
