There's a core problem this analysis overlooks: OpenAI and Anthropic don't have a moat. The Chinese labs are consistently able to replicate their LLM capabilities a few months after the fact, and then release open-weight models a few months later...
The only way for "Big AI" to become a thing is for them to establish a moat, and right now the only path to that appears to be achieving regulatory capture in the US, which is a fickle and unstable state of affairs.
That's why they're so keen to build out all these data centers; the massive capex is their only conceivable moat. Whether all those additional parameters actually make a competitive difference is still an open question.
If your government weaponize AI against you it doesn't matter if the AI is American, Chinese or Uzbek
