The parent made a totally coherent commment that China closing off their open weight models would cede the frontier (and majority of AI users worldwide) to the USA. Nothing you said counters that point.
1. Selling access to the US? 2. Ship more and better software? 3. Talk about it publicly?
If you had a secret AI better than anything currently available the mere mention of this would crater the US tech investment sentiment.
They could even host these Chinese models through AWS and sell at-cost inference on Bedrock and obliterate the US model companies.
