NoteThe source text provided is an excerpt from Anthropic's public website homepage featuring news, product announcements, and company information. It contains no personnel records, staff listings, or any mention of Holden Karnofsky. While the source is from Anthropic's domain, it does not address the specific claim about this individual's employment, role, or start date. To verify this personnel record, a source that actually lists staff members or contains biographical information would be required. The absence of information in this particular source does not contradict the claim—it simply does not address it.
