Former DeepMind exec warns US nationalism in AI risks triggering arms race collapse

Harding's argument isn't just a safety warning in the abstract: it's a structural critique from someone who watched DeepMind operate inside exactly the kind of government-adjacent relationships she's now questioning. The insider positioning matters because it shifts this from outside advocacy to a credibility challenge aimed at the labs themselves.

This lands directly on top of the Anthropic coverage from early July. The stories around Anthropic adding security protocols to satisfy the Trump administration, and the subsequent global release of Fable and Mythos after safety testing, illustrate the precise dynamic Harding is warning about: compliance-driven access, where labs adopt government-friendly measures not primarily to reduce risk but to preserve market reach. What looked like a safety win in the Ars Technica piece on Anthropic's export clearance can be read through Harding's lens as exactly the kind of nationalist gate-keeping that entrenches adversarial postures. The Claude Code geographic monitoring incident from The Decoder adds texture here too, showing that geopolitical logic is already embedded at the tooling level, not just in policy documents.

Watch whether any other frontier lab executive with direct government-facing experience (current or former) publicly endorses or distances themselves from Harding's framing within the next 60 days. Silence from that cohort would itself be a signal worth noting.
