Even sending over a probe at 30% the speed of light would take 400 years, plus another 120 to hear back from it. No matter how interesting, for our human society it would be really hard to raise significant funds for a project that will only pay off in over 500 years, if at all. If they have similar lifespans, such a project might be similarly hard to get off the ground for their society.

That leaves radio communication, but the latest intel they have on us left earth around 1900. At that point we wouldn't have been able to receive anything from them. It's probably questionable if we would have picked something up had they sent a radio signal our way a week ago. Right now SETI might have a radio antenna pointed their way, but that won't last indefinitely, and these events are a bit hard to time from 120 lightyears away.
