AI progress continues to accelerate and the stakes are getting higher, so I’ve changed my role at @AnthropicAI to spend more time creating information for the world about the challenges of powerful AI.

Personal news: I've joined Anthropic to work on Claude Design. Very excited to be here and to learn from all the incredible talent!
