Britain's sovereign AI moment: the procurement choice. One inventor, thirty one filings, and the architectural alternative the country has already filed.
The patents are filed. The trade mark is registered. The substrate is built. The question is no longer whether Britain can build sovereign AI; it is whether Britain will procure the sovereign AI it already has.
