Assuming a 1g-only constraint for healthy multigenerational life, how should regulators explicitly prioritize and sequence investments between (a) AG orbital habitats designed as long-term communities, (b) rotational lunar/Martian industrial outposts, and (c) hardened Earth-based refuges, if the optimization objective is to maximize species-level survival per dollar while keeping non-domination and environmental non-degradation above specified minimum thresholds?

Answer

Prioritize in three stages, keeping 1g-only biology, non-domination, and environmental non-degradation as hard constraints:

  1. Near term (0–20y): harden Earth first, prototype AG
  • Primary spend: (c) hardened Earth refuges
    • Distributed bunkers / resilient regions with 1g, strong biosecurity, air–water–food redundancy, and governance safeguards.
    • Rationale: cheapest survival-per-$, no gravity unknowns, fastest deployable.
  • Secondary: R&D and demos for (a)
    • Small AG testbeds (short-radius centrifuges on stations, partial AG modules) to derisk health, engineering, and cost.
    • Governance pilots for non-domination/non-degradation in orbit.
  • (b) Lunar/Martian: keep minimal
    • Small, tightly supervised rotational outposts for science and industrial prototyping only, strict caps on population and high-risk capabilities.
  1. Medium term (20–50y): shift marginal survival spend to AG orbitals
  • Once AG demo shows:
    • Near-Earth health outcomes at ~1g,
    • Robust radiation shielding and closed-loop life support,
    • Costs within a modest factor of Mars-city concepts, regulators should:
  • Make (a) AG orbital communities the main off-world survival investment
    • Build one or a few medium-scale, high-safety AG habitats in cis-lunar space as multigenerational communities.
    • Tie scaling to audited self-sustainment and non-domination scores; prohibit frontier AI/bio-heavy uses that raise risk-export.
  • Maintain (c) at high but tapering marginal growth
    • Continue upgrades to Earth refuges, but direct new frontier-survival funds mainly to orbitals once they are proven.
  • Keep (b) as capped industrial/service nodes
    • Use rotational Moon/Mars outposts to supply materials and experience for AG orbitals; no families, strict population and capability caps, strong environmental non-degradation rules.
  1. Long term (>50y): dual system with strong caps on surfaces
  • If AG orbitals are validated at scale:
    • Treat (a) as primary off-world settlement path for families and multigenerational life.
    • Treat (b) as small, specialized work-sites that support orbitals and science.
    • Maintain a diversified network of (c) Earth refuges as baseline and backup.
  • Global rules:
    • Reproduction and child-rearing only in 1g environments: Earth and AG orbitals.
    • Non-domination: use licensing tying population and autonomy to governance scores; stricter caps for distant surface outposts than for near-Earth orbitals.
    • Environmental non-degradation: strong limits on lunar/Martian industrial footprints, priority to in-space resource use that minimizes planetary damage.

Summary priority order under 1g-only:

  • Sequence: (c) Earth refuges → (a) AG orbital communities (once proven) → tightly capped (b) surface outposts mainly as industrial/scientific support.
  • At no stage do lunar/Martian surface sites become primary settlement venues for multigenerational life; they stay rotational and subordinated to Earth and AG-governance frameworks.
