Every AI lab thinks it's the responsible one, and safety researcher Ryan Greenblatt says that's what keeps the arms race going

Redwood Research's chief scientist Ryan Greenblatt warns that current AI development trajectories carry a 50-60 percent risk of AI takeover, attributing the danger to competitive dynamics between major labs like Anthropic and OpenAI that prevent safety measures from being implemented. He argues the industry is moving faster than historical precedent would support for such existential risks and advocates for international agreements to slow the race.

Why it matters: As AI systems become more capable, understanding whether competitive pressures are preventing adequate safety measures is crucial for policymakers deciding whether to regulate or restrict AI development.
