Toby Ord — Notable For: The Precipice; existential risk quantification; effective altruism

NoteAll three elements of the claim are supported by the source text: (1) 'The Precipice' is explicitly mentioned as his book; (2) effective altruism is confirmed through his co-founding of Giving What We Can and the 'wider effective altruism movement'; (3) existential risk quantification is confirmed through his research on long-term risks to humanity and the book's focus on these topics. The source is current and directly about Toby Ord. The claim's 'as of 2026-03' date is reasonable given the source's content remains accurate.
