...but interstellar communication is incredibly unlikely to succeed—they are far away, we don’t know in which direction, and required energy is incredibly large.
That is why we can target Andromeda—the distance is good enough so they didn’t arrive yet and we can focus on many stars simultaneously and hope that aliens have very large receivers - maybe Dyson sphere-size. Also the main point is to affect local superintelliegce expected utility.

I still don’t think that works out, given energy cost of transmission and distance.
