>not seeing ... finds the true optimal That kind of assumes there is an optimal. It seems quite likely not so - that there will always be room for improvement in AI like we don't have a true optimal chess or go programs. They just get better and go up a bit on the ELO scale over time. like https://huggingface.co/spaces/lmarena-ai/chatbot-arena https://huggingface.co/spaces/lmarena-ai/chatbot-arena has a score for chatbots - 1506 for Claude Fable 5 at the moment for example. I guess the test for RSI is if it can make the number go up. It'll probably go through phases of self improvement being a bit rubbish, self improvement combined with human help being best which is probably where we are now, and humans not needed perhaps in the future.
