  •  Simple counter example (0+ / 0-)

    It's trivial to come up with algorithms that create chaotic output. Beyond certain thresholds, output is completely unpredictable. (See Mitchell Feignbaum's studies of chaotic oscillators)

    The difference between a simple oscillator that produces unpredictable output and a human that produces unpredictable output is just a matter of degrees. (We have a lot of inputs) There are no instances of the creation  of completely new information in human history. Every advancement or discovery builds upon previous advancements and discoveries.

    We may not yet fully understand how our brains mix and process information, but that doesn't mean that human comparable intelligence cannot be approximated algorithmically.

    •  That assumes that it's possible to (0+ / 0-)

      completely map a complex system, and that's a pretty big assumption.  Sometimes these things go from being a difference in degree to being a difference of kind.

      We may not yet fully understand how our brains mix and process information, but that doesn't mean that human comparable intelligence cannot be approximated algorithmically.
      The problem I see is that we don't know if they are yet.  And really calling them algorythmic says to me that they probably aren't, given that this is another case of comparing the brain to whatever our most recent technology is.

      The revolution will not be televised. But it will be blogged, a lot. Probably more so than is necessary.

    •  Still deterministic (1+ / 0-)

      Chaotic systems are completely deterministic... the same inputs always produce the same outputs, even if you are sure that that will be.

      We are probably talking past each other about information as it's a pretty vague word.  I mean information in a sense like this:  Today there is certainly information about elephants.  What about 1 billion years ago?  Was there information about elephants then?  I'd say no...that information had to be created through the process of evolution.  And it's not that there was 'zero' information about elephants... it was less than that... no information at all (how could you conceive of an elephant at that point).  Sadly, that's what would happen to the information about elephants if we manage to wipe them out. :(
