Humans can fail at some of these qualifications, often without guile: - being consistent and knowing their limitations - people do not universally demonstrate effective understanding and mental modeling.

I don't believe the "consciousness" qualification is at all appropriate, as I would argue that it is a projection of the human machine's experience onto an entirely different machine with a substantially different existential topology -- relationship to time and sensorium. I don't think artificial general intelligence is a binary label which is applied if a machine rigidly simulates human agency, memory, and sensing.
