"The Last AI Built by Humans" (arXiv:2609.11873, 33 authors) reviews 72 companies and teams and finds AI already executes and selects improvements. The paper introduces the Headroom-Closed Index to expose gaps in current LLMs, lays out a five-stage RSI roadmap (execution, strategy, experience-acquisition and environment-adaptation autonomy up to recursive meta-improvement), analyzes RSI requirements across scientific discovery, embodied intelligence and software engineering, and identifies key challenges to genuine recursive self-improvement.
