Anthropic Long-Term Benefit Trust — key-event: Zachary Robinson appointed founding trustee

NoteThe source directly confirms that Zachary Robinson (referred to as 'Zach Robinson' in the source) was appointed as a founding trustee of the Anthropic Long-Term Benefit Trust. The source document is dated September 19, 2023, which matches the 'as of 2023-09' timeframe in the claim. The source lists him among 'the initial Trustees' in the 'Meet the Initial Trustees' section. The additional context about him being CEO of Centre for Effective Altruism is not mentioned in the source (the source identifies him as 'Interim CEO of Effective Ventures US'), but this does not contradict the claim about his appointment as founding trustee—it is simply additional context not covered by this particular source.
