Benjamin Mann is a co-founder of Anthropic, an AI startup dedicated to building aligned, safety-first AI systems. Prior to Anthropic, Ben was one of the architects of GPT-3 at OpenAI. He left OpenAI driven by the mission to ensure that AI benefits humanity. In this episode, Ben opens up about the accelerating progress in AI and the urgent need to steer it responsibly.

In this conversation, we discuss:

  1. The inside story of leaving OpenAI with the entire safety team to start Anthropic

  2. How Meta’s $100M offers reveal the true market price of top AI talent

  3. Why AI progress is still accelerating (not plateauing), and how most people misjudge the exponential

  4. Ben’s “economic Turing test” for knowing when we’ve achieved AGI—and why it’s likely coming by 2027-2028

  5. Why he believes 20% unemployment is inevitable

  6. The AI nightmare scenarios that concern him most—and how he believes we can still avoid them

  7. How focusing on AI safety created Claude’s beloved personality

  8. What three skills he’s teaching his kids instead of traditional academics
