Do you have a link to support that claim?http://www.cs.stir.ac.uk/~lss/NNIntro/InvSlides.html
That site is old, and of course does not cover recent discoveries in how plasticity works, for example, but the basic idea is similar.
I am a programmer by trade and am not unfamiliar with AI structures. : )
Elliquiy is not a decision structure. It is more of a data base that is storing 87 threads, even then when a user calls up the forum it is loaded line by line, one at a time untill everything is ready to be displayed.
Even on a single processor system, there are multiple logical units capable of handling instructions, the order of which is sometimes changed on the fly by the processor itself in order to improve pipelining - out of order execution. You may recall - back when it mattered - discussions about branch prediction, I'm not sure why you would not call those things a 'decision'. They are certainly more complex than the electrochemical summation that occurs in an individual cell of our brains. It's just that there are quite a few cells in the human brain to begin with.
Likewise, in order to support doing 87 things at once, elements need to decide what share of the processor they receive, how much memory they need to be allocated, disk and network access. Queries cannot be allowed to block each other, for example, otherwise everyone here would be at the mercy of smf's rather goofy database design. Some people are forced to wait several seconds when they first log in - but that does not block your access, for example.
The decisions are mechanical, even if sometimes randomness actually drives those decisions - certain elements of TCP require such, for example. But they are still decisions, and your own decisions and thought processes are basically an immense cascading series of summations.
