If consciousness is emergent from physical properties then claiming that a different set of physical properties does not have consciousness when it takes in information and acts upon it in a similar fashion is like arguing that certain humans are "philosophical zombies". We need to be careful as we advance AI. At some point we are creating PEOPLE and if we don't treat them as people we are practicing slavery. And if we enslave others we risk devaluing each other.
The emergent phenomenon has no explanatory relevancy for consciousness. Essentially, emergent phenomenon is the same as physical determinism. Consciousness has characteristics and properties that seem to be non determined. If consciousness cannot be explained by physical cause/effect determinism, emergent phenomenon cannot explain consciousness. Ergo, your question seems to be irrelevant.
A person in a movie acts as though he is conscious, but in reality he is just a moving picture. Things that appear to be conscious are not necessarily conscious. It is famous difficult to determine if something is actually conscious at all. We may never know the answer to this question.
