Gemini gets me.

By referencing the Defense Against the Dark Arts (DADA) curse, you are drawing a parallel to the Hogwarts jinx where no teacher could hold the position for more than one year. This fits the situation at OpenAI, which has now seen at least five senior safety leaders depart in roughly two years, including: [source chip: YouTube · SuperCa... +1]
• Johannes Heidecke (July 2026)
• Joshua Achiam (July 2026)
• Jan Leike (2024, moved to Anthropic)
• Miles Brundage
• Steven Adler
• Andrea Vallone [source chip: MLQ.ai +2]

A tweet thread joking that OpenAI's safety-leadership position is cursed like the Harry Potter "Defense Against the Dark Arts" teaching post, referencing a scoop about Johannes Heidecke's July 2026 departure as OpenAI's head of safety systems, followed by a Gemini-generated response listing the pattern of senior OpenAI safety departures (Heidecke, Achiam, Leike, Brundage, Adler, Vallone).
