From the investigation
The family connection
Dario and Daniela Amodei are siblings and Anthropic co-founders. Holden Karnofsky calls Daniela his wife; that makes him Dario's brother-in-law. Karnofsky was Open Philanthropy's CEO before stepping down in 2023 and later appears on an Anthropic risk-report byline . These are public family and career facts, not proof of METR control or an undisclosed transfer. TIME · Holden interview, p. 28 · Open Philanthropy leadership account .
Read the research & sources ↗EA and TESCREAL
Open Philanthropy's own account places Karnofsky in an effective-altruist institution. Gebru and Torres's TESCREAL paper groups transhumanism, Extropianism, singularitarianism, cosmism, Rationalism, effective altruism and longtermism into a critical historical argument. It is not a membership list. A 2024 TIME profile reported Anthropic saying neither Amodei sibling personally identified as EA, while acknowledging sympathy for some ideas. Documented relationships and policy proposals can be examined without converting an ideological label into proof of a coordinated bloc.
