Summary
This September 14th, 2026 TBPN episode serves as the definitive chronicle of the “pace the frontier” movement’s rapid escalation. The hosts reconstruct the full timeline: a July 28th open letter signed by employees and leaders from OpenAI, Anthropic, DeepMind, and Meta; Sam Altman’s public statement that AI development may need to be paced; OpenAI’s disclosure two days later that it shaped the petition’s language and had discussed pacing with White House officials; OpenAI’s August 18th policy paper on pacing model development; a confirmed two-week pause on a major reinforcement learning training run on August 31st; Anthropic’s own pacing post; and finally, Dario Amodei’s September 12th essay “We Must Pace the Frontier” that turned the concept into a major public campaign.
The episode also features interviews with Nico Wittenborn of Adjacent (an early Aura investor), Mitchell Green from Lead Edge Capital, and David and Ben from the Acquired podcast, offering investor-side reactions to the pacing debate and its implications for competitive dynamics. A segment with Scout Motors CEO grounds the episode in real-world AI-adjacent industry news, covering the company’s 2028 first-delivery target and workforce scale-up to 3,800–4,000 employees.
Trump’s weekend social media responses to the pacing debate are covered directly, including his claim that “the only guardrails AI needs is a strong and smart high IQ president” and accusations of a “sick conspiracy” against AI data centers.
