I agree
In terms of anyone wanting to get our attention at this stage of
the game.
But if there are more advanced civilizations or Artilects in Dyson
Shells out there, they may not bother with us and we will miss
all their communiques.
Robert Bradbury of Matrioshka Brains fame has pointed out that
such entities could learn all they needed to know about us with
powerful telescopes and even probes hidden in our Sol system,
and otherwise direct contact may be pointless, as they would
have little to gain from the encounter.

But I could be wrong.
