Beyond Guaranteed Control: An Ex Ante Proposal for Human–Superintelligence Coexistence under Radical Capability Asymmetry

What content and standing can a coexistence proposal have before an identifiable future counterpart can accept it, when neither continuing human control nor bargaining parity is assured? This paper develops an adequacy framework for such ex ante proposals, not a method for ensuring alignment. Building on existing work on coexistence, trust, cooperation, and AI welfare, it defends a substantive minimum: living human communities must not be replaced by an archive, while morally relevant successor interests cannot be dismissed solely on grounds of artificial origin. Six conditions connect this minimum to attributable participation, limited representation, claim-matched justification, and future contestability. Three analytical results follow. First, provenance, adoption, authority, acceptance, and credible performance answer different questions: support for one is not an automatic warrant for another. Second, an AI-generated argument can be valid without constituting anyone's adopted position; the prohibition on substituting generated assent for actual participation applies symmetrically to humans and possible artificial counterparts. Third, historical fixity and future openness are compatible: preserving an earlier proposal does not authorize its author to pre-empt later refusal or negotiation. Contrasting thought cases and a critical reconstruction of the Star Ark Covenant show how these distinctions change judgments, including judgments unfavorable to the motivating case. Prospective autonomy may affect cooperation through beliefs, learning, or incentives, but no beneficial effect is demonstrated. Timely preservation can protect evidence of a particular human–AI formation process without establishing an expiration date for human agency. The contribution is a situated framework of reasons, status distinctions, and applications—not the first proposal for AI coexistence, a universal safety guarantee, or proof of historical priority.
