    discovered by our technology for centuries, probably 10's of millennia, because they waste most of their communication energy spilling it out into space.

    On the other hand, if they should discover cell phones and TCP/IP within say one lifetime of broadcast, they may efficient enough that their signals don't leave their planets at any rate detectable much beyond their own systems.

    In that case we'd only have maybe a century out of several billion years, per star system, to discover an intelligent species between when it went audible and when it went quiet again.

    I think on average there shouldn't be any intelligent life we can discover, that use technology we understand, found by technology we have.

    Now on the other hand if they remain spacefaring capable for say thousands of years, they may discover physics that allow them to discover and visit us incognito, with only occasional fleeting traces dismissed as superstition and hallucination.

    If they should discover some hypothetical Third Motivation that would cause them to regard us other than as prey or resources, we wouldn't know why to look for them nor how to interact with them even if we should discover them.
