Lately...The Peter Principle has given way to the 'Dilbert Principle.' The basic concept of the Dilbert Principle is that the most ineffective workers are systematically moved to the place where they can do the least damage: management.

The computer may be incompetent in itself--that is, unable to do the work for which it was designed. This kind of incompetence can never be eliminated, because the Peter Principle applies in the plants where computers are designed and manufactured.
