We've been dark for thousands of years, and we've been emitting waves for just a few centuries. Who knows if we will switch to optical/quantum communications in a century or two, and we'll completely stop emitting radio waves, and then our "wave emitting" period will be just a blip in history.

especially since the waves travel at lightspeed so the first wave should be at a distance of 200 lightyear at most
