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

NoteThe source directly confirms that Zachary Robinson (referred to as 'Zach Robinson') was appointed as a founding trustee of the Anthropic Long-Term Benefit Trust as of September 2023. The claim's date (2023-09) matches the source publication date (Sep 19, 2023). However, there is a minor discrepancy in the additional context: the source identifies Robinson's title as 'Interim CEO of Effective Ventures US', not 'CEO of Centre for Effective Altruism'. This is a factual difference in the context provided, but the core claim about the appointment as founding trustee in 2023-09 is confirmed by the source.
