Counting on radio waves is problematic.
We had intelligent life on this planet for tens of thousands of years, we’ve had radio for just over 100 years.
Further, the presumption that we will forever onward continue to communicate with broadcast radio waves of sufficient power to reach another solar system may be a false one. It may turn out that there is a very small technological window when high powered radio waves are common to a developing civilization.
Given that there is no reason to assume that alien intelligent life would be restricted by our moral codes, why do we want to force contact? What we really want to find is a planet full of unintelligent life, that we can colonize.
All the cool advanced civilizations use communicate via quantum entanglement. The coolest ones have the new iTangle - now with more cattle mutilation apps.
Yes you are one of the few that have stated what I have believed for a long time. We are already moving from high power radio to more distributed lower power radio. This will continue. What is scary though is that creatures far away may continue to monitor high power radio for periods long after they use it. They might receive our transmissions from say the early 1900s and dispatch craft that arrive in 2025 or something. They arrive and wipe us out.
