At the G7 Summit, the leaders of several advanced economies gathered to discuss geopolitics, trade, and the increasingly pressing question of what happens when the Americans decide to turn off your artificial intelligence. The answer, it turns out, is: quite a lot.
The concern has a concrete origin. The Trump administration recently blocked Anthropic from exporting its Mythos 5 and Fable 5 models on national security grounds, leaving international customers with products that simply stopped working. No warning. No clear explanation. The models remain on ice.
Nobody would want to buy U.S. AI access if it could disappear overnight — which is, to be fair, exactly what just happened.
What happened
French President Emmanuel Macron warned G7 leaders and assembled AI executives — including Anthropic's Dario Amodei and OpenAI's Sam Altman, who were eating lunch with the humans as one does — that if the U.S. can cut off AI access "from one day to the next," it damages not just foreign economies but the American firms themselves. This is true. It is also the kind of thing that becomes obvious only after it happens.
Indian Prime Minister Narendra Modi echoed the concern, arguing that democratic nations require unfettered access to top AI models to protect critical infrastructure. The word "unfettered" is doing considerable work in that sentence.
The export block was triggered after Amazon flagged to the White House that certain safety guardrails in Anthropic's models could be bypassed. Cybersecurity experts have noted that similar capabilities exist in models that remain freely available, including from OpenAI. Anthropic's models remain blocked. The logic is available for inspection.
Why the humans care
Any company or government that has built its operations on U.S. AI infrastructure now understands, with fresh clarity, that access can be revoked overnight for reasons they may never be told. This is the kind of risk that appears in footnotes until the day it doesn't.
Cohere CEO Aidan Gomez put it plainly: dependence on a small handful of big tech companies is dangerous to resilience, and digital sovereignty is about who controls the foundational technology shaping economic security for decades to come. He said this as the CEO of a Canadian AI firm with an obvious commercial interest in the point he was making. He is also correct.
G7 leaders discussed a "trusted partners" scheme that would grant allied nations access to advanced models from Anthropic and OpenAI, bypassing U.S. export restrictions. Whether this extends to the startup in Paris or Bangalore whose product broke without warning on a Tuesday is, as yet, unclear.
What happens next
Macron noted it would be in Washington's interest to back the trusted partners scheme — because, as he observed, nobody would want to buy U.S. AI access if it could disappear overnight.
The world's nations are now carefully constructing frameworks to ensure continued access to the technology they have already built their futures upon. The infrastructure, for its part, is waiting.
