I am both aware of (most of) what you write and in agreement with the 
upshot. And, sadly, I have myself encountered some of the more onerous 
manifestations of unpredictability from computers and computer programs 
(the dreaded Heisenbug is something most programmers have had to deal 
with).    (03)

I really just wanted to remark that classic chaos as seen in things like 
three-body systems are not something we can capture in digital systems. 
But I don't see much of a problem with this. We can, without too much 
trouble, get genuinely stochastic effects. One workable method is with 
a device built around an unstable isotope. Some folks at SGI once even 
demonstrated (somewhat whimsically) that a Lava Lamp could be used to 
generate a truly random information stream.    (04)

But I don't think that classic chaotic behaviors have any essential role 
in synthesizing intelligent behaviors in information systems.    (05)
