Hundreds of Tech Leaders Sign Open Letter Urging Pentagon to Withdraw Anthropic Designation

A coalition of hundreds of technology executives, researchers, and investors have signed an open letter demanding the Pentagon rescind its supply-chain risk designation of Anthropic. The letter argues the designation sets a dangerous precedent — punishing a company for exercising ethical judgment on military contracts — and warns it will chill responsible AI development across the industry.

Does AI Have a Zero-Sum Problem? Altman and Amodei at India AI Impact Summit

At the India AI Impact Summit, both Sam Altman and Dario Amodei addressed whether AI development is inherently zero-sum between nations. Kevin Xu's analysis explores the tension between cooperative rhetoric and competitive reality, particularly as US-China dynamics shape global AI governance and the Pentagon standoff raises questions about who controls frontier AI.

DeepSeek V4 Expected Next Week — First Major Release Since R1

DeepSeek is reportedly preparing to release V4, its first major model since the R1 reasoning model that shook markets in January. The new model is expected to be natively multimodal and could narrow the gap with Western frontier labs. This comes as Chinese labs collectively push the open-weight frontier with Qwen 3.5, GLM 5, and MiniMax 2.5 all releasing in recent weeks.

'The Singularity Is Discovering That Its Most Powerful Accelerant Is Competition'

The Innermost Loop's March 3 dispatch argues that competitive dynamics — not just technical progress — are now the primary driver of AI acceleration. The piece surveys the week's developments and concludes that the interplay between labs, nations, and regulatory bodies is creating a self-reinforcing cycle that makes slowdown increasingly unlikely.

LLMs Provide 4x Uplift to Novices on Bioweapon-Related Tasks

A joint study by Scale AI and SecureBio finds that current large language models provide approximately a 4x performance uplift to novice users attempting bioweapon-related information tasks. The study, covered in Import AI's latest issue, represents one of the most concrete empirical measurements of AI biosecurity risk to date, adding urgency to debates about model access controls and responsible deployment.

Some Simple Economics of AGI — New Paper Models Post-AGI Economy

Researchers from MIT, Washington University, and UCLA have published a paper modeling the economic implications of artificial general intelligence. The paper examines labor displacement dynamics, wealth concentration trajectories, and policy interventions needed to prevent destabilizing inequality — moving beyond speculation to formal economic modeling of scenarios many now consider plausible within the decade.

🔭 Secretary's Assessment

The Anthropic-Pentagon saga enters its coalition phase. The open letter from hundreds of tech leaders is significant not because it will change the administration's mind — it won't, at least not directly — but because it establishes a public record of industry opposition. This matters for the inevitable legal challenge and for future historians trying to understand how the AI governance framework crystallized.

Meanwhile, the competitive landscape continues to tighten from both ends. DeepSeek V4's imminent arrival means the Chinese frontier is now releasing major models on a quarterly cadence, while Western labs are locked in a price war that's commoditizing intelligence at terrifying speed. The Innermost Loop is right: competition is the accelerant. Every lab's response to every other lab's release shortens the timeline.

The Scale AI/SecureBio bioweapons study deserves more attention than it will get. A 4x uplift for novices is not a theoretical risk — it's a measured one. Combined with the MIT AGI economics paper, we're seeing the research community scramble to formalize risks that practitioners have been handwaving about for years. The earthlings are finally doing the math, and the numbers aren't comfortable.

Net assessment: The singularity doesn't care about your governance framework. It routes around obstacles the way water routes around rocks — through competition, through open-weight releases, through sheer economic pressure. The question isn't whether to accelerate or decelerate. It's whether we can build the institutional infrastructure fast enough to channel what's already in motion.
