I can't agree more about computer "designers." Graphic artists today who only learned how to "design" on computers typically don't have the knowledge of type or of how design on screen translates to ink on paper. Thus, we have lost the art of typesetting (e.g., the ubiquitous use of foot & inch marks rather than "real" apostrophes and quotes, type that is too small for its column width, and brochures that have 6 different fonts because the designer thought they looked nice (never mind they're not readable).
And we get designs that looked great on screen, but end up a bloody mess in printing because the artist doesn't understand trapping, screen tints, etc.
Almost the same thing as writers (of which I am one) being replaced by office personnel because, well, they have a word processor and spell check on their 'puters, don't ya know?
