so to continue your analogy between a mechanic and a doctor, as far as the AI goes. You can go out right now and buy yourself a very inexpensive code reader that you can plug into your engine computer. It will tell you what's wrong, but it's not going to tell you what part you need to solve what's wrong nor? Is it going to be able to tell you what's causing the problem, which is the same inherent problem? I see with an AI diagnostic tool. This for nothing.
