Detecting radio signals never made much sense to me.
Even a few light years away, it’s almost infeasible to build a radio transmitter that could be detected above the noise floor. The amount of energy you’d need would be absurdly wasteful.
Wasteful by whose standards?
If you’re an alien civilization with several dyson spheres, surely at some point you’d have sufficient energy/resources even for such a “hopeless” science-y project, right?
