Inside Anthropic's quest to instill morality into its models — 357-comment HN debate
NYT details Anthropic bringing religious scholars in to help encode values into Claude; the 144-point HN thread skews hard skeptical ('bubble-phase research'), but this values-tuning is the layer that decides how Claude agents behave on ambiguous requests.
