Agree with tentenko and Dark Lord. AI is just a program, where we define their intelligence. Some industry tend to overuse the word "intelligence" in their product. Like, this equipment is intelligence, it has self-diagnosis system, linked with world wide web, automatic send a email to your account on any information that you want, got this sensor, that sensor. Just plug and play. Very intelligence... Ya, I have heard that many many times.

But the fundamental of this intelligence is just a special program. But for real AI, it is suppose to have self-programming ability, where it can learn new skills (basically the program, rewrite a new program on itself).

Implementation on robotics, like humanoid is still too far-fetching. When the programmer (human) is still unable to program a humanoid that can mimic human movement, like of a soccer player, how are they suppose to write a program, that can self-program on this movement?

About human brain, I think I read, or watch, in ripley before, where a man lost half of his brain due to serious accident. Yet after he recover, he didn't lost his ability to think or move around. So, can we say that we only use 50% of our brain? Maybe our brain has redundancy also... like a back-up or something...
