Naturally, many people have asked why I resigned. In the wake of many recent safety-related resignations at OpenAI, some have wondered whether my own resignation was safety-related.
It was not. The main reason I resigned is that it became increasingly complicated over time for me to simultaneously be (a) an AI governance grantmaker at Open Philanthropy (my day job), where we support a wide variety of organizations including some who work on US AI policy, and (b) a Board member at a US-based frontier AI company (though I’ve never held any Anthropic equity).
I wish Anthropic the best of luck in its mission, and I continue to think Anthropic’s leadership team takes the challenges of AI safety, security, and public benefit very seriously.
