The core problem is that until you can define something precisely there is no way you can build that thing. This is the fundamental concept in designing anything artificial at all. By precisely I mean defined formally using mathematics. The problem with all the "words" that are associated with intelligence is that they are very very vague. So the question, as of now is not can we create real AI but it is more of can be even define, precisely, what we mean by real AI? What does self recognition or learning even mean?
