I think merely one Voyager Record[0] is not enough. We need to be sending millions of these in all directions right throughout space, and spaced out over decade intervals. Then there's a greater possibility of discovery/contact. We already do this to some degree with the Arecibo message[1], but probes like Voyager are better IMHO.
