PHYSIX OBSERVATION
The ban covers only civilian departments, which shows that Washington's concern about DeepSeek is more a political gesture than a technical assessment. Open-source models are already embedded in US corporate product chains, making a blanket blockade extremely hard to enforce. The real signal is this: AI competition is sliding from a technology race into geopolitical camps, and developers' technology choices will be forced to factor in compliance costs.
