At present the only difference is the human brain is far more malleable and adaptable than is a machine. Our most flexible AI is generally based on supervised learning. That still requires human interpretation and verification to work properly. I think you can also state that machines generally lack the ability to discern expansive context unless explicitly trained to do so. Granted, it will happen. True AI requires these things. At present all ML needs a push from a human to become more "intelligent."
