David Manheim @ Association for Long Term Existence and Resilience (ALTER)

NoteWhile the source confirms David Manheim's association with ALTER (he is listed as a contributor and authored multiple organizational updates), it does not explicitly state his title or role as 'Executive Director'. The source discusses the organization and its funding, and shows Manheim as an active member/author, but the specific claim about his executive director position is not directly addressed in the provided excerpt. This is unverifiable from the given source text alone.
