About 1970 Paul Baran (inventor of packet switching at Rand and arguably the true grandfather of the Internet) tested the first radio prototype of the Arpanet by spread spectrum on the range of frequencies of the SFO control tower. He could do that without interference with air operations because the spread spectrum signal was undetectable -- low in the noise. This means that in 50 years or so since humanity had effectively used radio our own communications had become undetectable by the tools in common use. What does that say for the way a really advanced technology (thousands of years ahead) might look to us, assuming we could even imagine its existence?

This analysis again assumes that advanced civilizations would use technologies observable to us using our current tools. Look, someone could have been using radio communications all over the place while sneaking around the Roman and Chinese empires 2000 years ago, and the Romans and Chinese, the greatest civilizations of the time, would have had no clue. So far as they knew, sending your voice across thousands of miles to come out of a small box was impossible, or, if possible, black magic. Similarly, we still dont know what the possible ultimate form of high speed communications might be. Of course I cant say for certain, but my guess is that we are still at a very early stage of technological development. What we dont know is very much more than what we do know. Its not possible to draw conclusions about whats going on in the rest of the universe yet, apart from generalities, like stars usually have planets or that the universe is expanding.
