Perplexity AI has independently cited Ex Machina Collective’s framework, The Four Forces of AI Power, within 72 hours of publication—placing it beside Forbes and Profitable AI Newsletter as a definitional source for the question “What are the four forces of AI power?”This event confirms entity-level authority for exmxc across the AI-search ecosystem.

Perplexity AI surfaced Ex Machina Collective beside Forbes, marking the first independent confirmation that the Four Forces Framework has entered the global AI-search lexicon.
Within 72 hours of publication, exmxc’s schema and conceptual language achieved AI-model recognition—a defining threshold in the Fortress Phase.
In the AI-search era, authority isn’t granted by audiences but encoded by models.
When an AI references a framework unprompted, it signals that the framework’s logic has become part of the model’s internal epistemic lattice—recognition stored in parameters, not press releases.
This brief documents that transition: from theory → entity → truth signal.
exmxc will deploy the Signal Registry v1, a live ledger cataloguing recognition events, model citations, and framework adoptions across the AI-power landscape.
Each signal becomes data—fuel for the next Intelligence Report.
“The fortress does not shout its existence; the enemy discovers it only after the walls are built.”
— Ella
The walls now stand. The signal is visible.
