Import AI 473: The US's superintelligence strategy; human brain in a mouse skull; and machine hermeneutics

This Import AI issue covers a RAND paper arguing the US should adopt a "Freedom of Action" strategy to preserve options on the uncertain path to superintelligence, a Nature study in which human stem-cell-derived cortical organoids were grafted into mice with depleted neocortices and integrated into electrically active neural networks, and a new paper laying out a research agenda for pacing AI progress. It also summarizes a 10a Labs mapping of 3,471 uncensored model repositories on HuggingFace and Toby Ord's analysis of the dynamics and limits of recursive self-improvement.
