I was impressed by the scene in Apollo 13 where the astronauts request confirmation of their calculations and several people at Mission Control dive for their slide rules. For several months after that, my standard response to statements like "We must implement multi-processor object-oriented Java-based client-server technologies immediately!" was "You know, FORTRAN and slide rules put men on the moon and got them back safely multiple times." Tended to shut them up, at least for a moment.
