RAND lays out 7 superintelligence strategies for the US; core advice is spend now to keep options open

RAND published a long paper mapping seven US strategies for superintelligence across three families—coexistence, denial, acceleration—and concludes the best near-term move is a “Freedom of Action” approach: spend money now on safety tools, monitoring, regulatory expertise, and societal readiness to preserve options. Five key uncertainties drive the analysis: danger proximity, coexistence feasibility, restraint feasibility, decisive strategic advantage, and suppression feasibility. Jack Clark notes the current US posture looks like pure acceleration—pressing the gas without seatbelts. The issue also covers a study where human cortical organoids were transplanted into newborn mice with depleted brains; these xenocortical mice showed intermediate behavior between normal and brain-damaged mice and could serve as platforms for studying human brain disorders.
