This article gathers key voices—like Roon and Geoffrey Irving—arguing that unilateral AI pauses won’t work and that only a coordinated, industry-wide slowdown can meaningfully reduce risks. It then covers the “Pacing the Frontier” open letter, signed by leaders at OpenAI, Anthropic, DeepMind and others, laying out steps for labs to publicly commit to pausing if competitors do, lobby governments, and build trustless verification tools.

• Roon argues unilateral pauses are futile since talent/compute just shift to other labs, while Geoffrey Irving counters that vague "magic" arguments against coordinated slowdowns have collapsed and concrete global plans are needed.
• A concrete five-step playbook exists for labs to coordinate a pause: conditional public pledges, government lobbying, public outreach campaigns, internal verification task forces, and "merge-and-assist" compute/talent-sharing clauses.
• Over 1,000 employees across OpenAI, Anthropic, Meta and other frontier labs signed the "Pacing the Frontier" letter urging U.S.-led international governance to deliberately slow AI breakthroughs, with Dario Amodei signing late and Altman notably abstaining despite OpenAI's account retweeting it.
• Hassabis, Musk, and Zuckerberg have not publicly backed the letter, and some suspect OpenAI/Anthropic engineered it to appear grassroots—but it still marks a shift toward treating paced AI development as serious policy rather than fringe protest.
