I postulate that a technical civilization would only stick with radio for approximately 100-200 years before moving to something better -- and something that we probably don't even know how to listen to
That seems extremely optimistic to me. The effects of electromagnetism have been observed by humans for thousands of years. It seems unlikely that we'll discover something capable of interstellar communication apparently without having a hint of that something currently, when we've had millennia of hints in the electromagnetism case.
P.S. I should mention that, if you think faster-than-light communication will be discovered, that would require such a radically different understanding of our universe as to be astonishing. In the framework of special relativity FTL communication enables one to break causality by communicating with the past. An example is the tachyonic antitelephone, which gives rise to a paradox:
The paradoxes of backward-in-time communication are well known. Suppose A and B enter into the following agreement: A will send a message at three o'clock if and only if he does not receive one at one o'clock. B sends a message to reach A at one o'clock immediately on receiving one from A at two o'clock. Then the exchange of messages will take place if and only if it does not take place. This is a genuine paradox, a causal contradiction.
This is why no physicists I know or am aware of really believed in the recent FTL neutrino experiment.
P.P.S. Also, your use of "postulate" should probably have been "hypothesize". A postulate is a basis for reasoning, like the principle of relativity. Your usage isn't technically incorrect, but your statement is clearly a guess rather than a fundamental principle of the universe.
