It is my belief that AI will not be advanced under current theory. The goings on inside the brain do not translate to data and information moving around and being "stored" in different areas. A more metaphysical approach might unlock how it is done. Seems to me a chemical/electrical interaction takes place and creates "something" new. That is it did not exist before. Hence the "birth of an idea." This process is applied to all thought which is then physically organized by the brain for retrieval and modification. The entire mechanism is fueled and supported by the body. How would a machine understand wind on your face, hearing sounds in a forest or any other sensory inputs that create/ enhance or add to our intelligence/experience? The mind and body work together to create intelligence. Machine AI can't duplicate this process. It might take created information use it, store it or manipulate it but can't actually produce or create thought. The best we might hope for is a combination of an organic brain and a computer that the brain can use to enhance or speed up information already created. Actual creation of thought is a biological process not mechanical process. The term AI was created, now we are trying to fit research and theory to produce something to approximate what we think intelligence and real thought is in fact. Before you can duplicate something you should first completely understand what you are trying create. We don't seem to be close to taking the first step.
