Physicist Brian Cox describes consciousness as the most complex emergent phenomenon we know — something deeply mysterious, yet rooted in the fundamental laws of physics. In principle, if the brain obeys physical laws, a sufficiently powerful computer could model every neuron, every signal, and every interaction. But here’s the unresolved question: we still don’t know how consciousness actually emerges from brain activity. This is where AI and AGI change the conversation. Even if a machine perfec
