I think the closest we will come is detecting radio signals from another species. But like obviously 2 way communication would be almost impossible due to sheer distance.
Sadly the universe is filled with enough random radio radiation that its unlikely any coherent signal is going to travel more than a few light years. With our current technology there could be an identical version of earth around the nearest star and we probably couldn’t detect it.
The signal isn’t destroy though. So one could argue that isolating it in the noise is doable with enough math.
Obviously the real limit is still distance since we’d need a radio dish like the size of earths orbit or something to pick up a signal from 200LY away.
This is the correct answer.

Probably with virtual telescopes, smaller receivers arrayed throughout the entire solar system, like EHT but biiiiiiiigger
