Another level of objection to the use of computers is in the area of experts. People are sure the machine can never compete, ignoring all the advantages the machines have (see end of Chapter 1). These are: economics, speed, accuracy, reliability, rapidity of control, freedom from boredom, bandwidth in and out, ease of retraining, hostile environments, and personnel problems. They always seem to cling to their supposed superiority rather than try to find places where machines can improve matters!
