Let's be honest, if Voyager is ever intercepted by another spacecraft then that other craft is likely to contain... us! We know where it is, and the chances of anyone/anything else out there bumping into it must be tiny. Surely the chances are that we'll go and hunt it down for posterity once we've sussed proper interstellar travel?
(Aside from that: the sheer thought that the Voyagers still work, and are so far away, just boggles the mind. I can't comprehend either the distance or the coolness of the humans that made them and keep them going. Outstanding.).
