If you could prove not that one particular "simple" system is
Turing-complete, but that huge classes of simple systems are, *that*
would be an interesting result.
(Presumably such a result would include deciding exactly when a simple
system is or isn't Turing-complete.)
I still wouldn't describe it as a "new kind of science". Indeed, from
what I can gather, NKS isn't some sweeping new paradigm. It's just a new
and unusual way of looking at and thinking about things. That's not to
say there aren't interesting things to be learned from this point of
view, but it hardly rocked my world.
Fractal geometry already tells us that simple rules can generate complex
behaviour. Chaos theory already tells us that deterministic, simple
systems can still be highly unpredictable. NKS doesn't seem to add very
much. There's a few small, specific things which are interesting, but
it's not nearly as radical as people are saying.
But then again, isn't this the same Mr Wolfram who claims that
Mathematica fundamentally transforms the way computer mathematics
happens? Or that Wolfram Alpha is going to revolutionise the human race?
Sure, Mathematica is a great piece of software, but I guess we should
take anything Mr Wolfram says with a pinch of salt...
