@joannejang The existence of dedicated steering roles for capability restriction shows how deeply safety concerns are baked into frontier model deployment at scale.

@joannejang Wonder if it's just overzealous guardrails rather than actual sabotage.

@joannejang It takes a person with a very particular set of skills, honed over a lifetime possibly with three-letter agency experience

@joannejang I wonder how "Head of Sabotage" looks on a resume? Maybe "Customer Dissatisfaction Lead" looks better?
