Not to quibble, but that was NOT an attempt to converse with ET. It was an attempt to legitimize the concept that intelligent extraterristials might exist in the eye of the scientific establishment. A very controversial idea back then. Dr. Sagan was using it as a publicity campaign to promote/legitimize SETI not to chit-chat with ET.
