Aliens' Perspective of Technosignatures from Earth
If an extra-terrestrial civilisation saw the Earth, what technosignatures could they pick up? What could they learn about life on our planet and human civilisation in particular? I'm discussing that with Dr Michael Garrett who is the Director of Jodrell Bank Centre for Astrophysics.

Now just for the fun of it, Imagine that someone out did see us but they are technologically no more advanced then we are and they speculate about how advanced we are in their now that is dependant on how far out they are. So if they are lets say 200 lightyears out and they detect a civilization (us) we would then be 200 years further. And then the next fun, they send us a message, or we find them and we becomes interstellar pen pals with a 200 years delivery time with our messages. Now that is a long time to wait for an answer so perhaps we would have a continues datastream going instead. Swapping technologies would be easy but probably not really meaningful due to the delays but there could be a cultural exchange. Shakespeare is timeless after all.
Does there come a time in a civilization's development when a decision is made to abandon looking for Technosignatures after a long period of disappointment?
I doubt it. There could be temporary halts to the search but whenever new technologies to perform the search comes online the hunt will begin again and there is the difference between bio signatures and techno signatures. Suddenly, someone invented something new that can be detected as a techno signature. Never give up the search.
