To be deterministic a event must have a cause, but it is not necessary for Chris de Morsella to know that cause. However if no cause exists for Chris de Morsella to know then its random. > The brain is not a random state machine, > If it was the brain would be pretty damn useless except as a hardware random number generator, and I can buy one of those for $20. > it has a definite direction of flow and we experience a clear and > consistent outcome. > And that is why when somebody behaves oddly in a way we don't understand we say "why did you do that?", we demand to know the cause of their action. If they say "I did it for no reason" we tend to think they are a bit demented and their action UNREASONABLE. > > Watson was based on self learning algorithms > Yes, Watson was constructed in such a way that it was capable of extracting facts from its environment, and if its method for doing this were not deterministic what it would be extracting would not be facts but gibberish. > To characterize a self-learning machine that "learned" what associations > -- and what meta-associations as well -- because it is often on the meta > information that algorithms operate -- as an example of determinism is > really stretching it. > Exactly what is being stretched? For all the trillions of facts that Watson knew there was a reason it knew every one of them, even if it was too complex for 3 pounds of grey goo inside the head of a certain type of bipedal hominid to follow the very long logical train of thought. > Watson was so astoundingly successful on Jeopardy precisely - -I would > argue -- because it adopted a non-linear and non-directed approach. > OK, what's your point?

Turing proved almost 80 years ago that causality does not necessarily mean you can determine what it will do even in principle, much less in practice. In general if you want to know if a 100% deterministic Turing Machine will ever stop all you can do is watch it and see, and you might be watching quite literally forever. >>>>I never claimed we would someday understand how to make an AI more >>>> intelligent than ourselves, I only said that someday such an AI would get >>>> made. >>>> >>> >> > >>> And how are you sure it has not already been achieved. > > >> > >> Because computers don't rule the world.

So that I can thank you for educating me and correcting my error please tell me when I said you must understand something to use it, and more specifically please tell me when I said if humans don't understand how to make a AI then a AI will never get made.

Maybe its doing important stuff and you should just give it more time, and maybe its stuck in a infinite loop and you should reboot; even if you could look into the computer's chips and read their memory state in hexadecimal it probably wouldn't help you much in deciding on what to do. >> It is entirely possible that we will never understand the fine grained >> workings of the brain, but that won't matter because the computers will >> understand it. >> > > > And you sate this based on what assumptions? > The fact not assumption that the very fastest signals in the brain move at about 100 meters a second and many are far slower, and the fact not assumption that the speed of light is 300,000,000 meters a second.
