Radio transmissions might be an ancient form of communications to an advanced civilization. It could be like us talking to each other with smoke signals.
At this point it can only be speculation as to what future technology will be invented. Before radio, all we had was wire lines. Who predicted modern digital communications over vast distances 100 years ago? I am not more capable of this than the next guy but I leave the probability open for future advances since I have seen many during my lifetime.

The fact of the matter is any civilizations out there able to receive our signal should have been transmitting at least 100 years ago and we should already have detected them. It appears that we are unique. Many are predicting we will not be around to receive any answer. http://www.physorg.com/news196489543.html Frank Znidarsic So besides SETI attempts, what would be our best chance to detect ET life? At least, i think they should emit low amounts of infrared (You've got to stay warm in winter, right), some kind of heat signature, but to see something you must be inside their cone, what do you think ? Dont know.
