This conversation has me thinking of Rucky Rucker's "FreeWare" [1] and the
movie "Contact" [2]

If information begin propagation through space in a wave that does not cost
energy to maintain, if/when a civilization capable of detecting and decoding
that message acts upon it - there exists some  likelihood that there is some
compatibility to make interaction possible.

This likelihood is pretty small though.  Consider the EM radiation from
radio/TV/phones/satellite/wifi/etc - now imagine what creative leaps it
would take to make one of those devices meaningfully detect let alone decode
a signal intended for a different device.  (your best chance is to make a TV
play the audio from a radio signal, but your radio is nearly useless
understanding packet-encoded data in the wifi frequency)  Given the
increased challenge of spread-spectrum communications, you can imagine how
much "data" may be completely undetected in "white noise" (earthly or CMB)
