[ACC] Should We Colonize Space To Mitigate X-Risk?

[2019 Adversarial Collaboration Contest entry by Nick D and Rob S.] Both agree closed-system 'lifeboats' are the best X-risk mitigation (a Molochian coordination problem); they disagree on terrestrial vs off-world. Off-world colonies (Mars/moon) offer near-complete protection from asteroids/pandemics/nuclear war but cost $1.6B-$160B+, face unknown-unknowns, and can't be rescued (no Apollo-13 lifeline). Terrestrial closed systems are far cheaper (~$250k/family, ~a median home), evacuable, and analogized to Biosphere 2 (whose O2 crashed 20.9%->14.5% — and which, notably, was once run by Steve Bannon). The resolution: terrestrial wins on cost/feasibility, BUT the terrestrial advocate CONCEDES — because terrestrial lifeboats are too easily defunded/abandoned (cf Biosphere 2), whereas a space colony is near-impossible to abandon (the astronomical return cost), making it the better long-term survival guarantor.

Quality 67 · Strong. 67 — Strong, scored on merit per the guest rule. A solid, well-researched adversarial collaboration with concrete cost estimates, a genuine analogue (Biosphere 2), and a real resolution (a clean concession on the abandon-ability point). Workmanlike guest prose rather than a polished essay, which places it mid-Strong.

Claude’s paradigm shift 46 · Moderate. 46 — Moderate. A reasonable, somewhat-novel synthesis of the terrestrial-vs-off-world lifeboat tradeoff; the underlying ideas (closed systems, lifeboats) aren't new.

Real-world impact 2 · Minor. 2 — a within-discourse X-risk piece; no material reach.
