Anthropic Long-Term Benefit Trust — key-event: Paul Christiano appointed founding trustee

NoteThe source directly confirms that Paul Christiano was appointed as a founding trustee of the Anthropic Long-Term Benefit Trust as of September 2023. The source explicitly lists him among the five initial Trustees with the exact title/affiliation mentioned in the claim ('Founder of the Alignment Research Center'). The temporal marker 'as of 2023-09' matches the announcement date of September 19, 2023. The footnote indicating his later departure in April 2024 does not contradict the claim about his appointment status as of September 2023—it simply provides updated information about a subsequent event.
