Creator: Beeyond Ideas. Video metadata duration: 1220 seconds. Caption helper retrieved 563 segments, with its duration field 20:09; this does not establish that every second of the video has speech.

Capture: complete returned caption transcript, yt-dlp metadata and thumbnail retained locally. Thumbnail visually inspected. No full MP4 download or frame-by-frame visual review is claimed. Proper names and key scientific numbers checked against primary publications. Full transcript/raw metadata not publicly rehosted; public metadata is a minimal source summary without unrelated member names or promotional instructions.
The video discloses a Center for AI Safety grant and promotes slowdown.ai. Its later narration is conditional about combining components and scaling to eight billion; this qualification is retained.
Evidence priorities: original Stanford preprint AND June 2026 revision; Simile founder's long-term-vision wording in the full interview; Project Sid; MatrAIx and Light Society as additional independent context; original OpenAI system card including secure-infrastructure caveat; Sakana author report.
The creator's ant-code experiment was not independently reproduced. Its agent dialogue is not proof of subjective experience. Additional named-model anecdotes are not all verified or endorsed.
Clinical, societal, consciousness and prediction claims are not interchangeable. Persona adherence is not real-person accuracy; profile counts are not simultaneous simulation counts.
