I believe designers should eliminate the unnecessary. That means eliminating everything that is modish because this kind of thing is only short-lived.
Good design is making something intelligible and memorable. Great design is making something memorable and meaningful.
Quiet is better than loud.
All too much of the man-made is ugly, inefficient, depressing chaos.
Design should not dominate things, should not dominate people. It should help people. That's its role.
