Import AI 473: RAND's US superintelligence strategy, human brain tissue in mice, and machine hermeneutics

RAND published a paper arguing the US should adopt a "Freedom of Action" strategy to preserve options on the uncertain path to superintelligence, built on four pillars including a human-AI ecosystem and an AI-security architecture. The paper lays out seven archetypal strategies across coexistence, denial, and acceleration, and identifies five key uncertainties such as danger proximity and coexistence feasibility. Separately, researchers grew chunks of human-like brain tissue inside baby mice with depleted mouse brains.
