An interesting point about the radio visibility of our civilization is that it was incredibly short lived. Sure, we have some unique items that may be visible if specifically searched, such as radiation or organic chemical signatures/ratios. But the whole thing about blasting space with radio and TV signals? Basically just a 100 year stint. Current devices are much more focused, so there’s less spill, and by going digital, identifiable waveforms are much rarer. We went form nothing, to being the social media addict of the solar system, to blending back into the static in a matter of a century.
