AI is a misnomer, the topic isn't about fake intelligence, it never is, we already write applications that emulate intelligent decision making. Machine intelligence is the more accurate term, and the only way we would measure a created intelligence would be against our own, it's all we can compare against (we could posit and associate intelligence levels with say, other mammals but we haven't fully reverse engineered any other creature's brain anymore than we have our own; at least as far as I know). It's very conceivable that at some point in time we successfully reverse engineer the human brain and build a construct which emulates that.
As it stands the human brain is very powerful and capable, and for the most part everything it is collectively conscious of compares against it poorly. The biggest thing that people see in a Machine's is total recall and speed, which is rare or unknown amongst humans. Evidence is starting to point to human brains as having an intentionally cloudy area for memory to be lost, for reasons that supersede the value of total recall, like for example mental health.
The fact is the intelligence that most people, laymen or otherwise are discussing is not a procedural routine. It's structuring is similarly dependent on the structuring of our own intelligence, while its also conceivable that we could blindly create an foreign intelligence nothing like human intelligence, its more likely that we would at least at first use the blue prints of our own design in constructing this intelligence, and thus that intelligence could very likely be based on similar conditions like emotions, the same as humans.
